I'm trying to edit this assembly so I can have it in different different positions in different workstations. I've created a new configuration, but when I change an angular mating condition to relocate the arm, it affects all of my configurations. I don't know what I'm doing wrong. I'm using an Solidworks 2017, SP5 on an HP ZBook 15 G3 with 32 GB RAM, and Windows 7 Enterprise. The assembly is attached.
