Preface: Haven’t really seen any threads about this so I figured I may as well start one. Also, I’m well aware of the Vex CAD discord server , but not all forum users or competitors are actively on discord. When I first started CAD, I didn’t know where to begin. I kind of just used the inspect tool …

Preface; I am an Inventor user, I acknowledge the benefits to Fusion(and others) but prefer Inventor for Vex assemblies and design. I do use Fusion for 3D printing and to share stuff with my team though. For the intricate assemblies that you mentioned, its completely different. What Boots and other…

[image] Max_Johnson03: As to designing a competition robot I was referring to designing a robot from the ground up, I think CADing an already built robot is pretty intuitive. I agree with your general process though –– normally starting from the chassis up makes the most sense. The precision …

the great thing about CAD is that you don’t necessarily need to start from the ground up. you can figure out important geometry, and worry about how you’re going to make your build fit the geometry afterward, not the other way around, and I find this leads to a more efficient and better performing b…

To add to this, I like to design around the scoring elements directly. For example, change up intakes could (and should) be designed around the extreme points of the goal zone. This will allow to have maximum torque at the high contact points on the goals and overall allow for a more efficient syst…

Typically I figure out motor distribution and subsystems before I even start cadding. Then I figure out the limits and most effective way to do each one in a file. Then start throwing everything into a main file and adjusting things to fit.

In regards to CAD techniques, it really just becomes more apparent as you start to design more often. Understanding what the game requires out of a robot and what your goals are in a match can greatly help understand what you want to do with your design. [image] Max_Johnson03: For the intricate…

[image] vexreally: something that can help is creating a semi-complete mockup through CAD, physically building it as a prototype, and playing around with it to understand how different manipulations can change the outcome. I really like this idea. Tapping into different learning centers of th…

friendly reminder to fully constrain your c channel’s FEA study

[image] Ethan5956F: friendly reminder to fully constrain your c channel’s FEA study Ethan, it needs to be all one part to have structural analysis done…

you can do FEA on assemblies…? besides what i was implying was that you should conduct a study on each hole c channel to find what the optimal length is for the forces described lmao

I think this belongs in this thread as well.
