Hi, I'm trying to decide the best way to design an asembly. The thing is the parts in this assembly are fabricated parts (different parts joined by welding). So for drawing purposes I've started designing each fabricated part as an assembly. Then make a super assembly with the small ones. Here comes my problem. There're some dimensions of one fabricated part (wich is an assembly for SW) that must be related with dimensions in other fabricated part (also a SW assembly). Then SW says "This part have operations defined in the context of other assembly. You can edit the part but you can't create external references to the components of the assebly".
