Stacking Triangles

Hello, first off thank you for your time. I have a class assignment to design a mechanism to stack triangles using a drawing program called “PTC”. Right now i’m looking into it and trying it out trying to get use to this program first, i also have some classmates who are excellent with PTC, but i was wondering if any of you could give me your ideas, drawings, etc on this topic for me. Thank you much again

Are you talking about 3d triangles like the tetras? It was the 2005 game of FRC. Try searching CD-Media for robots from 2005.
