I'm working on fully configurable assembly, where most of the dimensions will derive from 3 basic global variables: width, height and depth. The assembly is made out off 3 different extrusions. Global variables are incorporated in top level assembly. Originally each extrusion was a single part with multiple configurations. For the purpose of this exercise I had to save each "cut" as separate part, since global variables refer to dimension name, rather than specific configuration. Here comes a question: how do I link same profiles so that in BOM it shows overall length of extrusion to be used, and in cut list shows each of the separate lengths?
