Hallo, i want to sort the standard parts in my Model with an tcl script. So I want to mirror all standard parts into a Assembly with the Name "300". Further i need sub assemblies for all Screws, Nuts and Washers. For example the structure looks like this: 300 (standard parts) -301 (screws) -303 (nuts) -305 (washer) Furthermore the Comp should exist in the root assembly and in the new assembly. Could anybody help me with this Problem?
