I have a weldment part with 4 configurations, each with several parts that may or may not be in the other configurations. When I try to make a drawing of my parts I put in a weldment cutlist like normal, and finish my first drawing. I make a new sheet to put another configuration on and my new cutlist still shows the information on the first configuration. When I try to fix it to make the cutlist reflect the correct configuration my first cutlist changes and my number ballons go all crazy. How do I put multiple sheets on a drawing, each with different configurations of a weldment part, and make my cutlists reflect the configuration that each sheet represents without conflicting each other?
