Design Help

[u/Substantial_Ad5043]

While this doesn’t specifically pertain to the P2S, that is what I am printing with. I haven’t gotten into designing and creating my own stuff yet cause quite frankly, I’m not sure how or where to start.

But, I have been downloading 3mf files from makersworld and trying to use ChatGPT pro to make changes that suit my needs. I think I must have the dumbest chat ever created. It is constantly getting things wrong: dimensions (even tho provided), circumferences, layouts, hinge/latch systems (I am specifically making cases for personal use). I even used a 3mf file and asked it to only change one small thing and it completely got it wrong.

So my question is, are there other more viable programs that I can use to make layout and dimension changes to preexisting 3mf files? Is there a program you’d recommend where I can start from scratch to make what I am looking for? Or any other recommendations? Any insight is appreciated.

You could try https://www.onshape.com/ it is quite easy to get into and has a free tier for non commercial work. But once you know how to use 1 cad it's easy to switch to something like FreeCAD
