This will unfortunately take a medium effort, and I want to make greater strides with the rounding errors in official primitives first, since that is a more pressing issue.

Can you explain a little more about how one can find these errors? If it is "simple" math is it not able to be done pragmatically with a script of some kind? 

I am way new to the LDraw community and the part creation but I would like to give back and contribute. I have made a decent amount of side income from making and selling instructions using LDraw tools. If my giving back can be doing the boring stuff so you can get on with your list of awesome stuff then so be it.
