What projects are you working on?
Where are you struggling?
What software are you using?

I just started learning CAD on Inventor Pro and I now cry myself to bed every night, when does it end ?

Fusion360 is better and has EXACTLY the same learning curve but better support and more tutorials and online videos.

I learned using Autodesk Inventor.
Learning curve is STEEP, and I used to write CAD software, worked for and with engineers and know how to design for CNC.
Inventor does a 'few' more things than Fusion360 but F360 is DEFINITELY the better way to go.
What are you struggling with?
>>
>>800681
Looks like it could be milled but would sure waste a lot of a block to machine away.
3d printed in plastic would be my choice.

It's for arthritis. Having fewer "keys" will lessen finger movement dramatically. With practice, typing speed will increase for the same reason. The learning curve will be massive I agree.

I uploaded the grip to be printed with ~2mm thickness and no internal structure at all and the cheapest option that wouldn't melt inside a car was PA12 Nylon at ~€100, per grip - without any internal structure it would absolutely need. I won't pay $200 for two plastic parts so I'll most likely have to create a mold, laminate the outer surface with fiberglass and then use casting resin for inner structures. I haven't calculated exactly how expensive that'd be but I figure the material for one grip would then come in at around 25-35€.

If I 3d print an axel & rod what size should the rod be compared to the axel if I want it to be a snug fit? 1mm less diameter? or...?
>>
>>804538
Same size on axel and hole. Sand the axel until it fits. This will guarantee the hole not being too big.

Electric actuator from the 80s that I worked on last year. Sadly it was never finished. Too much electronics and don't have the rest of the drawings for it. This is in Inventor btw.

I also worked briefly in SW last year and picked up this year. Some exercise with a bit of basic rendering which I want to explore more.

Job searching sucks these days and I wish I could come up with some good ideas to put in my portfolio. When I see other people's work on YT and grabcad I feel like a loser who is never gonna make it.

I have a Nikon D3300 I use to take photos (although really any camera will do as long as it can take a series of photos in rapid succession), then I process the images using Meshroom.

For this scan in particular I took 200 photos, pic related is one of them.
The secret to the surface quality is the white stuff. It's corn starch mixed with water, I use a sponge to tap it onto the surface for detailed, high contrast patterns which Meshroom can pick up later. It's cheap, doesn't hurt or interact with car paint or other surfaces and you can wash it off with some water when you're done.
>>
>>808204
Shit, you drive like that bro?
>>
>>809694
Not sure what you mean - I remove the starch with some water after scanning.

You can use talcum powder for that. Apply it with a fine sponge. Cleans off better.

I used that when I was doing actual model building (before digital) and we prepared miniatures for filming on motion control rigs. The miniatures were taken from our shop to Image G in Valencia CA for filming. We dulled them down with talcum powder for pulling mattes against red backgrounds. Helped with spill and reflections.

Making extrudes is a bit like saying you’re painting when you’re coloring with crayons. People aren’t paying for Catia and NX licenses to do basic extrusions and revolves. Real CAD that you need real tools for is surfacing, which involves creating a book of sections and a ton of development.

Fusion360 or give up and blow away.
Been using AutoDesk products for years, but moved from Inventor after years and found Fusion360 simpler but lacking a few 'minor' yet HUGE things I still miss; like being able to reference values that are the results of calculations and in-design geometry rather than things I could know beforehand.
Although in Fusion360 the CAM tools seem to do the job.
>Everything free is useless; everything useful is expensive
Welcome to the real world.
>struggling?
Nope.
Just completed an interesting project that was supposed to be 'a one-week job just out of curiosity' that took me 6 months.

>what do?
I design things that get made in a 9-figure plant and have to work or I owe someone my house, one of my daughters and a kidney.
So far, things I have designed have worked... apart from that ONE time one didn't and luckily someone else got blamed for it and fired and two years later took a golf club to his wife's face.
No stress.
NONE AT ALL!
NO STRESS HERE!

The balls in ALL such bearings can be pressed in.
It's the cage that holds them in and the cage is supposed to hold itself in.

Can any Solidworksbros help me out?
I was given a file I should do some work on.
All the "parts" in it are features, with these blue icons I've not seen before.
When I try to edit any of them, it just tells me to locate the original file for the feature.
Can I somehow just force SW to turn them into editable workable bodies?

it's a step file. When opening the file does it ask you to run diagnostics and feature recognition afterwards like pic. related? After clicking yes, you should be able to edit the part like you do normally.

Yeah, it does ask.
However the mess I was given has overlapping solids, causing featureworks to not do much.

this is perfectly machinable, you just would about 5 setup operations, and a v block.
I could make OP's print in a day on a prototrak.
the only part that looks remotely challenging is this recessed slot, but I could get at it easy enough with a slitting saw.

I appreciate your suggestion, but it's insufficient for photogrammetry. You don't just need a matte surface, you need a high contrast non-repeating pattern to get good surfaces. Starch is $2/kg, a kg lasts forever.

This is one of those cute things they use to teach students.
Just as a though experiment, if I was making this in reality I’d break it into three pieces, so you’d wind up with a piece of flat bar as the base with some countersunk holes for screws, then the other two pieces are that big chamfered chunk on the end and the vertical part on the other. Drill and tap some holes and this is really easy to manufacture. Not sure how many places are selling 20mm thick material though but hey that’s a question for steel sales not for me.
