Answered: [VEX U] College 3D parts?

[anon50541363]

Hello Karthik,

I would like a clarification on the following from the VEX U rules. In the additional materials section of the manual the new 3D printed part rule has an ambiguity:

Two 3D printed parts, each less than 3” x 3” x 3”

A. Can I assume that this means that a “part” must be contiguous, that is one unit.

B. Does this also mean that assemblies that “trap” loosely-coupled (that is technically NOT contiguous, only pinned) parts are considered more than one part?

For example, this thing…

… can be 3D printed as one unit, but infact is made of multiple sub-parts.

C. According to the college VEX U rules, would this qualify as one “part” or four?

This is what I need to know. Thank you! -Cody

It would qualify as four parts, or however many parts make up that object.
