Robot Design/Modeling Software (CAD)

Is there a free vex robot designer for the computer? I am trying to think out ideas and my drawing skills are not great.

well, there’s Autodesk Inventor, you can use that to make a 3D assembly out of vex parts, its really useful and easy to use once you get the hang of it. and it is free for students and competitors.

I’d reccomend Autodesk Inventor. Students or anyone who claims they are a student can get it for free


I have tried Autodesk Inventor and it runs WAY too slow on my computer.

I have the same issue, so I run 3D Builder which is significantly lighter on the system. I made my own library for it which is linked here:


Fusion 360 is less resource hungry than Inventor, perhaps give that a whirl.


Thank You @vexreally for sending me those parts and suggesting 3D builder. I would have never thought that would work. Thank you.

If your school offers solidworks licenses, that’s what I use.

Dassault also offers free Solidworks licenses to VRC teams through their sponsorship program:

I personally use inventor but I know teams that use sketch up. Our school district has it downloaded on all of our computers but I think it is free. Its definitely not as good as inventor. Below is a video of another team that is using it.

The best free option for vex is robot mesh it is a free online coding IDE and 3D modeling software for Vex. The only complaint I have is that it is hard to navigate and change perspective and from my experience with it you cannot constrain parts.
