Let's say I have a beam part I want to use in multiple assemblies. I want to use the same file for all of its instances in the assemblies, but don't want to make a million-and-one configurations for every possible length I may want to use. Is there a way to create a part such that when it is part of an assembly, its length can be changed to whatever value I want without it altering the length of all other instances of the part in the assembly or having to save multiple copies?
