I want to faff about and make sci-fi prop concepts for fun, should I use moi or fusion? Is that plasticity3d a meme or worth looking at as well?
Rhino is based
>>899949I tried both for concepting and found fusion 360 to be significantly faster and more freeform, fusion 360 is the only time in CAD I've felt like I could make stuff as fast as poly modelling. If you already know 3d you can open up F360, watch a senechal timelapse and be up and making stuff in damn near 15 minutes.The pricing and weird necessary cloud integration is the only drawback.
What is the difference between AutoCAD and Fusion360?
>>899937>1k for a rhino keyLOLdo they really expect people not to just pirate this shit
>>900009I don't know but I tried inventor and it was a pile of shit while fusion 360 is smooth as butter so I assume every concept artist who is better than me uses f360 or Moi for a reason
>>900055...how is the remesher of fusion to create .obj meshes from the nurbs objects?
Will learning CAD really help me get a job easier than learning Maya?
>>899937Working on a hood for my car. Will be 3D printed in pieces, glued together, sanded, and used to make a mold for a vacuum injected CF hood.
need link for Catia P3 V5-6R2019 with SP6
>>900209Wouldn't it be better to model it as subdiv and then convert it to NURBS later?
>>900285sounds strange, but with subdivs it's a lot harder to get clean reflection lines while keeping your model structure simple. I've been doing subdivision modeling for 10 years now and when I tried it with another 3D scan I was only able to get this surface quality by using horrendous shrink wrap modifier stacks that made the model really hard to work on.
>>900051Why are you crying about the price of Rhino, idiot? Autodesk charge $3k a year for a lot of their software.
>>900324>>900051Rhino is the cheapest professional CAD/CAID program out there and the license is perpetual, so once you pay- you never have to do it again.
>>900205I'm not sure, but Maya has very good NURBS tools.
>>900339Retard
Need good CATIA course/tutorial that has decent introduction for beginners. Already worked previously in SolidWorks, Inventor and Fusion 360.
>>900423>RetardI'm not retarded. Maya's NURBS tools are excellent for ARTISTIC purposes. Not nearly precise enough for CAID, though. Good enough for entertainment and animators. Maya's NURBS tools are pretty much the same exact NURBS tools as in Alias/Studio, minus the precision and surface evaluation tools.
>>900526ok now compare that to anything made in fusion 360
>>900009AutoCAD is a 2D drafting program, with some 3D capabilities, while Fusion is a 3D Cad program
>>900644what's the difference between autocat and blender?
>>900526>Cad thread>Maya nurbs tools same as alias>Apart from precision>Cad thread>Apart from precision>Cad thread>I'm not retarded.
Use TAB and SHIFT+TAB to hide/unhide parts in a SOLIDWORKS assembly.
>>900526Absolute king retard.
>>900209I had an sw20 with a solar v6 someone plopped into it. car was a nightmare, no AC, no speedometer, no tach, no abs, had an exhaust so loud when I bought it that my left ear was going deaf on the ride home, ran rich no matter what I did for some reason, but what do you expect for $1500? I miss that car all the time.
>>900884That's a damn shame Anon, sorry to hear it's been totaled.Mine's a Spyder, bought it for $2.5k with failing precats then put in a new engine for $500. It's been running for 2 years now, I'm never going to sell it, it's too much fun.
>>900982it's not totalled lol, just was tired of having to fix things constantly and sold it to some dude in texas for $3500
>>900989ah then I misunderstood, to me it looked like "with a solar v6 (and then) someone plopped into it"but yeah, constantly having to fix shit is draining motivation fast.
>>900998also it was a solara v6, typo on my part. it's was a really jank job but damn was it a blast to drive when it was running
>>900717>>900746I'm not retarded. I'm giving people options. I'm sure there are lots of people who want to use NURBS that already know Maya.
I've got a new job and the company uses HiCad. Terrible. Only now do I appreciate how nice using Creo was.
Can I somehow keep my unpirated version of Inventor once my license expires? Or will it get bricked?I have student's license until november and Im wondering if I can keep using it later.
Redpill me on the best way to learn CAD on my own.
>>902639MoI 3D, $295FreeCAD is free but the UI is complete cancerRhino3D has more features than MoI but costs $1k
>>902639OpenSCAD, unironicallyKeep the cheat sheet open, learn the syntax first, look at the example models from top to bottomDon't immediately buy $300 software, don't use FreeCAD until you have at least 5 years experience in CAD (this is for your own sake, you will quit if you try to start with FreeCAD)
where do i get a job?
>>902640Moi has a long 3 month trial and is easy to learn. If you want to pirate it, get the full trial version off the official site, and the cracked beta version off Persia. The .dll packed with the beta can be used to crack the latest trial version.Personally, I do not have experience in other CAD programs, but I really like modeling in Moi as compared to Blender. For hard surface stuff, it is better than Blender + Boxcutter.
>>904029Can CAD Software be used for game models?
>>904080Yeah, as long as you don't need to deform them, which you generally don't.
I want to design autocannons as a hobby, though my background is in compsci. I want to use FreeCAD. Where should I start? What should my workflow be like? Thank you!
>>904080As a highpoly for sure, it's even a good base for handmade lowpoly topology. I wouldn't import it directly as a lowpoly unless the geometry is very simple and doesn't feature many patches.
>>904080>>904097I started out using blender years ago and ended up working on mostly architectural and industrial subjects because that's what I enjoy modelling. I am working on a project that is a game with lots of these subjects (pic related).I get satisfaction from arranging the polygons into the required shapes but this task is often very tedious and I wonder if I am being retarded by not taking the time to learn CAD, you know, something designed for exactly what I am doing in blender. One thing that gives me pause is I have imported CAD models into blender for 3d-printing related operations and I've noticed the geometry or UV layout is not optimal for my purposes at all. For example in the pic I posted it is basically many cylinders and spheres of varying diameter joined together at right angles. At perpendicular intersections I try to "collapse" the circular cross section into a square or rectangle in order to keep the vertex count as low as possible, and just for general ease in texturing, smooth normals, and so on. The CAD models seem to have an automatic geometry that is just 'whatever fits' and I'd have to do a lot of that work over again.So yeah idk. It's something I've been wondering about for a long time, it could be a huge time-saver, but I won't know unless I actually try it out and see how it fits into my current workflow. If I have to remake each CAD object in Blender I'd say it's not worth it, I can already get pretty good high-poly bakes from my modifier stack.
>>904302>The CAD models seem to have an automatic geometry that is just 'whatever fits' and I'd have to do a lot of that work over againThat's true, but with e.g. Rhino flowing surfaces with great reflections come so much easier than they do in Blender because you can first figure out the shape, then export to Blender and just snap your verts to the imported surface while you figure out your topology. In a sense, it's not doing the same work twice but doing 60% of the work twice and getting a 200% quality model.
>>904308You make a good point, I hadn't considered it that way before. I do feel limited by the available techniques in blender and this prevents me from making some things just because it is too tedious. For example the hemispherical protrusions inside the end caps of the model in the pic I posted before took something like an hour to get right. That feels too long for such a simple detail. If I was less motivated that day I'd have skipped that detail and the model would be less interesting. I've heard CAD programs described as "parametric" - my understanding is this means you are able to easily adjust parts of the model (diameter of holes, etc) without totally messing up the overall geometry. To go back to the hemispherical protrusions, I just noticed today they are slightly too large, and would prevent the removal several of the tubes in the center of the model. As the tube removal is an essential function of that device it is unacceptable and I consider that a violation of suspension of disbelief (very autistic, but I can't help it). This is a major headache to fix in blender and probably would take an hour or two of work. So if the parametric nature of CAD means what I think it does, it is clearly worth the time for that scenario. I'm definitely willing to try Rhino, they have a trial I could use.
>>900209basedWhat car?
>>899937Holy shit, just what I needed. I've been using blender+freecad, freecad naming problem and UI drive me crazy, I just downloaded solidedge community edition, and noticed you can also get solidworks for markers for $99/yr,anyone have experience with the latter two? I'm mainly making mounts/brackets/3D printed stuff. I liked inventor when I had access to it, but don't anymore.I just want parametric 3D CAD with a nice UI really. I don't need advanced features like simulation or weldments
>>901028When this many people call you retarded, you might want to reflect a little on your life.
Question from a complete noob who only gets the idea of drawing sketches and extruding them here and there.How to make something like the plastic seat in pic related?The front looks like a curved plane but the back side has these extrusions...
I need a 3D-CAD program that lets me design some crazy ass gadgets with bearings, magnets, coils and lets me simulate them.I'd really like "AutoDesk inventor", but that shits expensive.I'm not a student, nor work anywhere CAD is done.Is torrenting a cracked version ever malware free?Is using a keygen foolproof?I do admit I totally loved FreeCAD, but it don't physics simulate a moving generator model.
Why does /3/ hate Solidworks?
>>905806Expensive as hell.Great program, but unless you have access to it from school or work then you're not going to spend 1k a year to use it. I used Solidworks and Catia in school and they were nice.I guess you could get the cheap ass version for like 100 a year but that seems like a waste since fusion is free and does similar things if you're a hobbyist.

>>905374Make a curved plane and add extrusions to it,a lot of software has pattern modifiers for things like that
>>906029Cute rat/dog.
>>906184
>>906184Sorry, forgot to write that it’s supposed to be mesonyx >>906190Still, thanks!
>>906042>Make a curved planeThat's the question. How do I make curved plane when I can only draw a 2D sketch?
>>906307Draw a curve on one axis, and another curve on a different axis, then sweep the first curve along the path of the second.
>>904823MR2 Sypder
>>902639Pirate autodesk inventor. I dont like using inventor, but thats how I learned CAD in highschool. Now I only use openscad and cadquery cause i dont have to interact with people who use proprietary bullshit software. Granted i dont 3d model for school or work.
OpenSCAD and Solvespace. Solvespace has a good file format, OpenSCAD is code. Solvespace is now integrated into Blender, so it makes even more sense to learn it. OpenSCAD can be used for bionic 3D modelling as well (picrel), just different, but then combined with precise parts. Same should work with Blender and Solvespace code now, but with OpenSCAD everything is code.
What do you think of my idea? Took me about 10 minutes to put together and is currently in the early design phase. It helps with keeping the car dry when driving under rainy conditions.
>>907198openscad is a great way to flex your engineering degree.>>907333anon this is genius, you need to make a thread for this right now. I'm serious.
>>907338>openscad is a great way to flex your engineering degree.Is it though? I only learned openscad and cadquery after college cause all professors taught and used solidworks and matlab.
>>907437lol because it's awful for real world use, purely a dick measuring tool
Do you need to be autistic to get into CAD?
>>907578No, I'm only quite low on the scale. It's rather about technical parts (which need to be more precise). Also, about being able to change one value and other things change in relation to that. In case of OpenSCAD this can be done in text, so you could have another program change the file. Might get useful for combining models with machine learning. >>907338Nice, I might use these.>>907437The educational system tends to train people directly for jobs, not necessarily the best tools or if they're great then they're expensive.
>>907478Hmm idk about that. Maybe openscad is a bit cumbersome but cadquery seemsway better than solidworks and inventor. Like if you are a business that needs 3d modelling work its way better to manage your projects on github and have have all your designs be parametric. Also you dont get locked into an out dated version of software or a subscription service.Openscad and cadquery may make more sense in business pipelines than in a hobbyists skillset.
>>907991I think there's some truth to this, but there's also a lot of problems that would make it undesirable. For starters SCAD is a programming language, so your engineers need to know how to code and use git. You would basically be hiring engineers who are also programmers instead of purchasing a license for enterprise CAD software.On top of that SCAD is a functional programming language, so even if your engineers have some programming experience (probably matlab? idk) there will be differences in how the language works, immutability for example.Even then there are more fundamental issues, some simple operations on complex objects in SCAD are much more time consuming and prone to error. Fillet on a convex 3d shape, for example.Never used cadquery but I'm pretty sure most of these points you can substitute SCAD for cadquery/python.It's kinda a pipe dream I think, there probably aren't any businesses that use OpenSCAD on larger scales, maybe in a prototyping lab or something.
>>907578Come to think of it, wasn’t Chris Chan studying drafting at one point?
>>908209>studying draftinghe probably thought it was drawing.
how do you create a cad model w/ opengl or are there any C libraries?
>>908143>Never used cadquery but I'm pretty sure most of these points you can substitute SCAD for cadquery/python.Cadquery is way better than openscad with respect to making fillets and chamfers, there are even constraints (wtill wip though), and cadquery is OOP instead of functional.
Is there any reason to learn drafting by hand anymore? Like drawing your designs without using CAD?
>>908209He was, one of the Sonichu comic villains was a version of his CADD teacher at the college
Revit is bestRevit is best!!Freecad CRINGE.
>>908975Having basic drawing skills to sketch ideas to people is convenient. Otherwise, no.
Thoughts on moi?
Does anyone here have experience with TurboCAD? Picrel is what my work uses, but it's kind of obscure so googling a specific issue I'm having is hit or miss.I'm looking for good ways to learn the more advanced tools other than experimentation and reading all of the documentation which isn't that great anyway.
Forgive my brainlet moment, I don't usually model with surfaces. Does anyone know what the proper method in solidworks would be to fill this top face. it's a compound curve in real life so I can't just extrude the surface and the boundary surface tool just shits itself before I can even try it.
>>909748I got it working. The key was not to try and patch the whole face but to do it in two steps. I also closed the boundaries so they were closed.
>>908975It came in handy the other day when I had to draft a sink from a paper template. There are digitizing tools available, but ours was down that day. So I pulled out a ruler and pen and got to work figuring out the arc angles, lengths, etc by drawing straight lines. No need to be an expert, but the ability to understand how to get arc measurements from straight lines is helpful in a pinch.
Using CAD for cosplay instead of typical modelling makes integrating with electronics so much easier
Okay guys I have some questions, and I hope I can get some help. I am using FreeCAD to modify existing STL files, and I am trying to modify a object, and this will turn into two posts.First one, in picrelated, I and holding shift and leftclicking to select these, how can I autoselect that model there? This is a .step file, and there isn't any parts its merged together.
>>911017Second question is, how can I go about changing the model in pic related?My goal is to get the slot in the upper green square moved up by 2.2mm, I was thinking of cutting it in the bottom green square move it up 2.2mm and then fill the gap between the walls, but I am not sure..
What has the closest workflow to CATIA?Can't fucking stand Fusion360 and FreeCAD is too fucking obtuse. Mostly need something that works well with reference points/planes etc.>>908975Mostly to collect some rough sketches of your idea in front of you, as it's faster to do that compared to driving down all the details in CAD.And sometimes it's just easier to draw something simple rather than trying to autism it in CAD, especially if you're making something by hand.I would almost be better off doing a design I'm stuck on in Lego and paper instead of trying to fight some CAD shit that won't let me adjust placement simply.>>911017Selecting things is very finicky in freecad. There should be a way to at least filter what you're selecting.I have a way I'd position a drawing to just remake it if it's simple enough, but I haven't found a way to do it in freeCAD.>>911019This is mostly a negative/positive add/subtract ordeal, assuming you don't have access to the tree of operations and this is an imported solid.You make a positive solid around the slot you want to move and use the current model to subtract the excess. This leaves you with a negative that you can move around. Fill in the old cavity, then subtract the negative you just made where you want it relocated.That's the 'easiest' without just moving vertices themselves, which you shouldn't do for a parametric model.If freecad doesn't enjoy that, like it just wants to cut faces instead of cutting solids, you might have to remake the entire thing. Doesn't look like a complicated part at least.
>>911041you haven't tried rhino?
>>911045No, was looking into it but the gallery is full of rendered examples of mesh work, so it threw me off a bit.I'll have to line up some ideas to push through the trial perioid. Certainly cheaper than CATIA would charge, if they even bother responding to an inquiry, but a bit steep to dive into.
Why don't chuds use Blender as it can be a CAD program aswell?
>>911056Because they aren't retarded like you.
>Selecting things is very finicky in freecad.

Doesn't look like a complicated part at least.What I ended up doing was creat a block 1mm high and made the length and width big enough to cut it, and I used "compound explode" so I can have them as two separate pieces. After that I moved the bottom part 2.2mm down, and used idk exactly but it was described as "create a ruled surface from either two edges or two wires" so inside was still hollow, and I wasn't sure how to fill it, I started messing with boolean operations like fusion, or union, idk if they worked, I opened it up microsofts program 3d builder to use its tool fix and was able to import into superslicer to 3d print. I hope I can learn more and don't have to jump through these hoops like I did on this one.
Rate my mouse setup bros. I primarily work with large assemblies in Solidworks. I can do almost everything with my right hand.
One million years learning solidwork surfaces.
Does anyone know of sites I can get practice drawings from to model after? I'm talking about similar to studycadcam.
>>906657Do you find openscad time efficient? Is it slower than say inventor for basic shit?
>>913384https://au1lib.org/book/3062867/f513d7
>>899937anyone know where can i find a copy of vectorworks for a cheaper price or for free?It doesn't seem reasonable to go and start another useless course, or to wait until i get an employer who is willing to wait while i learn it thoroughly enough to be comfortable.
Anyone use moi?
How is the production process after the parts are created in the software?How do you turn these pieces into real objects?Are files sent to CNC machines?
>>913723Some companies take the 3D files, some companies want additional technical drawings.You can have parts CNC machined, 3D printed, get parts laser cut and bent out of metal sheets, etc.
>>900526>good enough for entertainment :)))))Kill yourself, all 3D art should be mathematically perfect and use real curves. go ahead and tell me otherwise jewish wagecuck nigger. keep making your hard-edged fake bullshit for daddy's sheckles.
>>913723I own my own CNC machine and do all of my own design and CNC programming. For reference, everything I tell you is done using solidworks, camworks and executed on a SIEG KX3 milling machine.1. You design the part in solidworks.2. You move over to the camworks plugin for SW. This allows you to define the stock, fixture, ect.3. In camworks you will create an operations tree to define the milling (or/and turning operations) that you will use to take the piece of stock to the finished part.4. Once you complete your operations programming, you will export Gcode for your specific machine using a postprocessor which you select through camworks and is either defined by you, or provided by your machine manufacturer.5. You take your stock and place it in the machine, touch off your relevant zeros and then start your program.
>>913723>export .3MF >print on 3D printer :DDD

FreeCAD is only free if your time is worth nothing
Is blender decent for cad stuff? Im already familiar with it but I can just pirate solidworks and use a vm if its no good.
>>916709as someone who has just recently got into CAD, i first tried blender with cad sketcher and it wasn't intuitive at all, if you're already pretty familiar with CAD you can give it a shot but imo solidworks is way better
Noob question here, is there an easy way to import models from Fusion 360 to blender where the components/bodies in Fusion are individual objects in Blender?I can import the design but the entire model is one single object. My workaround is to import each individual object, since their position is exported too, then all I have to do is import them all, but sometimes it's too time-consuming if a design has dozens of bodies.
Which do you prefer, Inventor or Fusion?
Is modern Alias any good? Or is the name the only connection it has to the oldfag version of Alias that ran on IRIX?
What are the main CAM programs people use for Solidworks? Excluding integrated plugins
>>918483I use Mastercam and before that Solidcam. If you have a new version of SW, then the included Solidworks Cam is very good.
>>918483Sorry my tiny brain didn't read, "excluding integrated plugins". I think the previous owner of my mill used lazycam, but I can't remember.
Can I commission someone to model some gun furniture for me? I want to turn my Mateba Grifone into pic related
>>920375bruh you're missing the metal barrel furniture which acts as the most important structural part for the foregrip. would be cheaper to get some c-clamps and just 3d print that sumbiatch some clothing
>>918447Tools are modern and updated but interface is from 80s.
I wanted to get into 3d printing mechanical parts, which CAD software should I use (pirate)?I'm experienced with blender but I guess that's not the best choice for this job.I tried freecad but the experience was terrible, are all CAD programs like this?
Does anyone have experience using salome ? I'm torn between fusion360 and salome and need some input to make up my mind.
>>920589No the silver portion of the gun is where you actually attach furniture. It has 3 holes that you screw in. Pic related is what it looks like with normal furniture.If you’re talking about the actual barrel shroud, I would have to get someone to machine a longer one for me. While that’s possible it would be incredibly expensive and I don’t care that much
How long would it take to get into this kind of work? Like an entry level position?
>>913384here's a quick exercise for anyone that wants some practice.
>>899937Just getting into cad/fusion360 for 3d printing. I'm trying to design a series of itx/atx boards that can be printed in pieces and feature mounting points for sbc mount plates and hdd's/sdd's.Current approach with channels to slid the plates into isn't working very well, even tweaking for tolerance.Any advice/tutorials for designing 3d printable latching mechanisms? I want to try a different approach, but have no clue how to design connectors.
Bump
Is there a proper way to simulate hydraulic cylinder forces in solidworks simulation? Basically I need a pair of equal opposing forces acting on arbitrary, non-fixed faces, that are always aligned with each other even when the model deforms. The latter is why just a pair of forces along the selected direction don't seem to work quite right (they misalign when the model deforms and this induces extra moments that shouldn't be there). Spring connector doesn't work on arbitrary faces. Adding the actual cylinder into the model increases complexity and solution time, as well as amount of things that could go wrong. Is there any other way that I missed?
>>904383>my understanding is this means you are able to easily adjust parts of the model (diameter of holes, etc) without totally messing up the overall geometrythat's exactly what "parametric" is supposed to deliver and it does deliver 90% or so. There still are edge cases where Rhino will e.g. fail do do a boolean properly (mostly if "non-clean" surfaces or curves are exactly on top of each other and similar edge cases), but Rhino has Grasshopper which is used by architects to do, among other things, eaxactly what you're envisioning.And if you want to start a bit on the easy side outside of Grasshopper, Rhino has a "History" functionality, where you e.g. "record" extruding a surface along a spline into a tube with a profile, and whenever you change the spline the tube will adapt as long as the "history" has been recorded.I myself haven't really used Grasshopper so far because I'm using Rhino for car panel surfacing ( >>900303 ), these kinds of surfaces don't reall benefit from that style of modeling.

Where did it all go wrong for Fusion?
>>926173What happened now?
What's the difference between CAD software and Blender, Max, Maya etc.?
>>926359Blender,Max,Maya are mostly used for VFX or game work. It's usually less work to model something with these but the models aren't 100% accurate.Rhino, Solidworks etc are used mostly for designing products, i.e. something that has to be manufactured, has to adhere to strict tolerances, perfect surface reflections etc.
>>922706should be possible, i'd rather use multi body physics software like adams or recurdyn
how did people design shit before computers? i am legitimately curious. i am a machinist by trade so i can read a print, but actually MAKING a print and knowing how everything moves together seems ridiculously complex. i really want to design my own 2 stroke motor and 3d print it, even if it's not technically usable i want to go through the long and painful process that is figuring out how to make one. the problem is that i'm a retarded freecad main and it doesn't let me move and model shit. so i want to either do it manually on paper or something else
How the hell do I cut this?I've spent hours trying every combination of reference geometry and chamfer and it's just not working.
>>929638fusiontard here. id break it down into 3 separate parts, the middle, left, and right. id make a plane with 2 of those axes and then a drawing, then make the shape I wanna cut then extrude it out, repeat for the 2 other sections
>>929640oh and if extrude doesnt work because desired shape is not perpendicular, use sweep instead
>>929640That's actually how I got started here, I think. It didn't do the entire job, though. So I went a bit further.I got one side 70% of the way there. Tomorrow I'll try to do the other side by building up instead of cutting.>>929031Drafting used to be its entire own career. You'd have engineers and technicians/machinists/mechanics like you do today, but the engineers often also had drafters working under them on big tables, using all the old-timey equipment like compasses and slide rules, just to convert rough sketches and ideas from the engineers into proper spec drawings.
>>929641>oh and if extrude doesnt work because desired shape is not perpendicular, use sweep insteadDamn, I completely forgot that was an option! Thanks, anon.
>>929643you're welcome :)been using fusion as both a tool for work and for my own personal projects I hate parameterization, freeforming everything is so much more fun
Anyone know any free CAD software that would let me import an image to trace? Or how to do that in SolidWorks?

>>929638>make surface>cut with surface>remove uneeded bodies
>>929690You can copy-paste an image into solidworks. It would then do its worst to make sure you know it doesn't like it, but it can be done and even used in practice.

how much does a cad job pay?
>>930752>Unstable>Bloated>Horrendously overpriced and arbitrarily difficult to buy if you're not a corporation buying 100+ licenses at a time>Company loves to acquire competitors and then destroy their features rather than go through the trouble of integrating them into the rest of the bloated messWhen you can get it for "free" via a university or workplace and you're not working on anything too complex, it's great. But it's hideously painful trying to get it as an individual user, and it sucks to use on larger projects.
we do a little 3d printing
Is there any suite that supports multicore rigid body simulation? Bonus points for accurate friction and material adherence. Solidworks can suck me off, I've been looking at NX Siemens, but I can't find any documentation. I'm sick of sitting on powerful hardware but limited by retard practices. >inb4 mate chain design

Hello 3 anons, I have ~7 years of experience using Solidworks ""professionally"" and before that I was a machinist.I work with a shitload of newer coworkers who have no idea what they're doing in SW and I wanted to make videos to teach them how to make things the right way.Instead of making videos internally, like a good wagie, do you guys think it would be worth to make a youtube channel for soliworks tutorials/tips as a native english speaker?Is there anyone for Soldworks thats similar to what DefaultCube is for Blender? I don't watch tutorials so I have no ideaI lurk on /3/ because I want to learn blender and want to give back some of stuff I learned through you anons
>>933719As you know, doing CAD work heavily depends on what exactly you're doing CAD work for. Setting up a drawing for metal cutting and bending is vastly different from modeling a CNC milling part, which itself is different from 3D printing parts, pressed parts, etc. Then you have the diffrent kinds of surface quality - in automotive you'll be working with surface continuities of G2 and up while continuity is G1 at best for e.g. invisible non-critical mechanical parts. For structurally important pieces you might need G2 due to better load distributaion, etc. So, before you start modeling you already have to have the manufacturing process in mind, that's why I think it's very hard to make "one size fits all" tutorials since people use CAD software so differently.
Does anyone if it's possible to get a cracked copy of Moi 3D? I'd like to incorporate it into something I'm working on but I don't want to be limited by the trial duration. Tried looking for a torrent or something, but couldn't spot something that looked legit.
I need to use this faggot ass software for a final jewelry assignment, does someone have a safe torrent? Every single one I found on cgpeers are filled with virus reports, never seen that shit before. I'm not trusting none of that nor I want to install the evaluation only to waste time cleaning the installation for my system if I ever need it again.
Bros, does anyone know how to make a repeating pattern like this in Fusion 360? I know how to do it manually but there must be an easier way. I'm trying to figure out the buttpad raised ridges.

Solidworks/revit designers and other CAD jobs could be automated in the future by AI? Like in 10 more years?Dont want to put so much work on something that could be automated.
>>908143Why do they need to learn git? They can use something else if that’s easier, or not use version control at all.
>>911940whats going on with the left ?
>>918447Autodesk Alias and ICEM surf is what you use for late stage modelling in the car industry. Early stage polygons has become popular since a few years but Alias is also used early, Icem no one except some frenchies. For design that is. Engineers use Catia afaik
>>935564>cadlets struggle with simple shit like thisoh nononono cadbros this cant be happening...
>>918155Inventor, because you can actually pirate it as it's a standalone software, compared to the online-only cloud based Fusion360.But if you're willing to pay $60/month, then you can go with Fusion.
>>937424when i was in the industry 5 years ago or so it was pretty 50/50 between catia and alias depending on the house. chrysler preferred catia, i think more for the collaborative file sharing system, secure cloud storage for security reasons, and non destructive history for iterative changes. alias had a reputation of being the faster and more freeform modeler, but as it had destructive modeling with poor history (at least in the version i used), every time a designer wanted even just small or iterative changes you had to rebuild all of the surfaces.
I'm looking for drawings of parts/assemblies that are leaning towards medium complexity, as I would like to practice my modeling. Something like picrel is too easy, and I really dislike the style of dimensioning, which seems to be common on these types of drawings for some reason. Any links or repositories would be appreciated, thanks.
i'm trying to improve my surface modeling skill in solidworks, any tips ? i'm not good when it come to complex models where a shape need multiple functions, I don't know where to start and how to do it.any course in pdf form would be more than welcome too.

Hey /cad/, I'm wondering if anyone here has recommendations on a trackball for Catia. I've noticed lately that my wrist is getting sore from flicking the cursor to the bottom right corner of the screen to work in the popup context menu and want to try a trackball out. My work is ITAR restricted so I'm unable to install any software for function buttons. Due to how the Catia views are controlled, I'm not sure how usable a finger operated trackball would be with the middle mouse button. Does anyone here have experience with trackballs and catia?
>>934271bro you virus shit just blocks craks
>>899937Testing, I want to know if my fellow engineerbros are doing fine
>>930929Bit of a late comment. I recently stopped my yearly subs as I am (supposed to be) moving from freelancing into a wagey role. Account manager at local reseller was a bit PO and tried to use the monthly "development" penalty, which has to be made up before you get back on subs, to force my hand.Grumbled a bit when I pointed out that there are other systems out there that do just as good a job, with the advantage that they are still being actively developed, unlike SW where it would appear our subs are going towards a cloudy system no-one really wants...
>>939012I experimented with using trackballs before, but not on CAD software, and all I can say is that it needs getting used to, and it doesn't magically fix your "wrist problems". Definitely worth taking a shot though, although I'm not sure if Catia even supports trackballs
>>939012maybe a vertical type mousei never ried but seems mor anatomica
>>904080Yes, but they don't animate the model. So it works for static objects like trashcans, weapons, etc. or for the character models before animation is added. You just export into the appropriate format that your game uses which is usually 3ds or obj or stl in the case of 3d printing or you can use file type converters. Most 3d model formats are pretty similar and most file types can be converted by most programs out there.
>>904383Trick: make cylinder. use center of flat part of the side of the cylinder to make a sphere. Boolean them together. Now you have pill shaped cylinder. Use that pill shape to boolean cutting into any object to make your arches. You're welcome. Or draw shape with splines and revolve to create 3d shape and use it the shape way.
>>905374To make the back part I'd make a box with about five segments and pull the polygons backwards a bit to make it curved and the bottom ones up to make the arch and the top corners down to make those curved and then make a cylinder and clone it across to make one row and then clone them down to make another row as needed and group them and boolean them to cut the shape out of the back to make the holes.
>>935715It's good. One thing it's especially good at is making threads. That's really hard in rhinoceros.
>>900720cute pic
All I'm trying to do is make a rectangle in FreeCAD and I'm getting filtered so fucking hard.I can't see or edit the values of any of the constraints, and if I try to make new constraints I never get asked to input a value (despite having it enabled in the settings) so I'm stuck. I've looked around and read the 70 page PDF on Sketcher mode but no solution. A fucking rectangle.
are CSWA or CSWP certifications worth it?Im thinking about finding a job out of my country, nobody here seems to care about design certifications, but on most job listings in Australia and Canada that seems like a minimum requirement.I have a portfolio of my designs and a lot of years of experience in solidworks , my original plan was maybe learn Creo or Fusion, but some of my coworkers said certifications are more worth it. I dont mind spending money but i dont want to waste my time lol.
>>944209Bong here, using Solidworks since 98+. Never known anyone outside of a VAR that had either.Do a lot of surfacing of consumer products and clients / potential employers want to see what you can do, not what certs you have.Not sure about more trad engineering. Last time anyone questioned my skils, they looked at my Pro/E, Solidworks and Rhino work, sat me down in front of a copy of Mechanical Desktop (a while ago!) and made me model a bent sheet metal bracket without using any sheet metal features. Cheeky twat (coincidentally an Ozzy).
THIS IS A PUBLIC SERVICE ANNOUNCEMENT.If you're using solidworks, be sure to enable dynamic reference visualization.It allows you to see a selected feature's parent/child dependency in the history tree.You're welcome.
>>944459Of course. And also Show flat tree view is very useful when you need to find a specific sketch amongst thousand of features. And when the order of sketches is weirdly done.
>>944459Minor problem. Have this turned on in a model of reasonable complexity (say 1000 features+ in some castings and interestingly surfaced power tools I've worked on) absolutely destroys the performance / responsiveness of the program as you casually drag the mouse over the tree and it searches every bastard feature in the tree.Same sort of shit with instant3d. Oops accidentally dragged a sketch entity at the top of the tree and fucked the model, irreversibly trashing splines... also bloody irritating with dynamic highlighting on.
>>899937Rhino is a nice AutoCad knockoff, priced better for students, who don’t know they can get AutoCad for free. Static modelers are cool if you like spending your time in 30 years ago.If you’re not in Inventor Pro or Solidworks you’re wasting your time and limiting your designs.
>>944483Haven't used Inventor since V9 but Solidworks surfacing is a PITA and limited unless you add Xnurbs. Some stuff (surfacing) Rhino is much better at if old-school clunky. Aaand you can muck around with Grasshopper.Did an NX trial a little while back. That's where my money would go if I was to continue doing demanding surfacing. It's also a bit clunky compared to SW but the surfacing is better. We might yet get it but that's for more 'engineeringy" stuff.It's a shame DS have stifled the development of Solidworks to protect Catia.
>>918155Inventor, because it actually supports complex assembly operations and PDM unlike Fischerprice360

I am retarded, can anyone point me in the right direction? Im trying to understand how to model curtain walls in solidworks without prior 3d software experience. Playing around with weldments but it seems that im not approaching this thing right. What im trying to achieve for starters is a model with all correct lenghts and machinings for each profile
>>945883Not sure that your data is private on a non-commercial account. Otherwise, probably fine.
>>946240Unless there's some more specialized solition I'm not aware of, using weldments is certainly the correct approach. Use corner settings and trim/extend tool to join all the profiles properly (though it might be a bit of a pain with complex profiles like yours), then you can generate weldments table that would list all the pieces and their lengths you will need. Non-weldment parts can also be included, but they won't have their dimensions automatically filled.Very convenient to make a numbered part list and an assembly drawing with all the parts numbered. Dont forget to put numbers on the actual physical parts after you cut them and you can basically turn your brain off for assembly.
Should I power through the autism that is FreeCAD to make enclosures and basic 3D printable parts? I've made a few but I'm not very good at it (they were simple cuboid enclosures so they work well enough)I am an EE by trade so enclosures are only meant to hide the electronics inside
>>914042>>good enough for entertainment :)))))>Kill yourself, all 3D art should be mathematically perfect and use real curves. go ahead and tell me otherwise jewish wagecuck nigger. keep making your hard-edged fake bullshit for daddy's sheckles.Alias sucks.It's user interface is GARBAGE!

>>899937Pro Tip for anyone in university:Get yourself a rhino student license it costs around 100-150bucks. You will be able to keep.it for a lifetime and upgrade it for a fee to the next version Incase you wish to. (For the most part not necessary especially if you get rhino 7 right now). The great thing about the student license is that McNeel let's you keep using it after university. While I used a cracked rhino version during uni I decided in my last year for that reason, it has really paid off so far

>>955622I dont have SW at the moment because I graduated and the student license expired, but here's what I did:Sketch1: Placed on the front plane, I created the side profile of the part so I could reference it to place planes and so I wouldn't need to dimension some things later on.Plane1: Referenced Sketch1 to create a plane perpendicular to the front plane and along the top surface of the bottom plateBoss-Extrude1: Profile of the bottom plate including holes, placed on Plane1 and extruded downwards (SW is smart enough to know that circles inside a sketch = holes in an extrusion) Uses Sketch1 for the limits of the extrude.Plane2: Reference Sketch1 to create a plane perpendicular to the front plane and parallel to the top plane at the top of the part.Boss-Extrude2: Placed on Plane2, extrudes the top profile of the cylinder, including the full width of the side lobes, down to the surface of the bottom plate, (again, the center hole is included in the sketch and the extrude feature is given the top face of Boss-Extrude1 as the stopping condition)Cut-Extrude1: Cut downwards from Plane2 to create the new flats on the lobes, (Cut extrude can have multiple independent profiles to cut with in the same base sketch, same as boss extrude)Plane3: References Sketch1 to create a plane parallel to the top plane, centered in the keyway of whatever you want to call that horizontal feature.Boss-Extrude3: Uses Plane3 to create the profile of the horizontal feature, again including the hole. Extrude limits are set as mid-plane and reference Sketch1Cut-Extrude3: Uses front plane, cuts the keyway on the horizontal feature as well as cutting all of the horizontal holes on the cylinder. Uses through-all as the end conditionBoss-Extrude4: Uses front plane, gussets, multiple profiles in the same sketch
I am super new. Is there a way to "copy" a constraint? Or "reuse" a constaint?Say I want to copy that 5mm constraint to that point of line. How do I do that?But it would be better if I change that original 5mm constraint, I want the point at top to be updated as well. Is there a way to share/reuse a constraint for something else?As I am typing this, I noticed I could add a 0mm constraint from top point to bottom point. So they are always on same X line. Is that the way to do this?
>>957201Not sure program but could you put a central construction line and mirror or constrain symmetrically to it? Black lines in pic rel means its fully constrained, would be purple if not

So, i got an old centroid controlled mill working at the shop and have free reign over it. People are already wanting parts made, i'm used to QCAD for plasma cutting and such as well as 3d printing. After trying freecad and getting filtered i'm trying out fusion 360.I'm making a flange somewhat similar to this. I have the basics done, but i need to add 3 bolt holes similar to pic related. I used the circular pattern tool to get them spaced how i need them from one another, but i need to offset these holes outward from their point of origin. Then add extra material to accomodate them. Any tips?t. 3d cadlet
>>957820Nevermind, figured it out. Had to make an offset for my original bolt hole, apply a circular pattern modifier to it, and extrude the offsets.
Any of you guys work at firm doing CAD professionally?I fucked up and got a CAD degree and now the only place I can live is in a shithole city.
