Chris, Awesome, thanks for the post! As for dimensioning, do you mean that it's hard to tell how big something in when reading your code? To understand better, is it because 1) You didn't break it out into logical modules, and would like to see better practices in breaking out modules? 2) You want to query a module for its dimensions, and don't know how? 3) You want to be able to see the dimensions in the drawing itself, and don't know how? Thanks!
