I am working in an assembly. I will give an example of what I'm trying to do. Basically I have a cabinet faceframe, and I want to draw a door that is in context with the frame so it will update with it. I can easily get this done, but I also want the door to be able to use a hinge mate to open it up. I can't seem to get this to work. I have brought in a hinge and used the hinge mate successfully, so that is not the issue. The problem is my part is made in context so it doesn't want to move. I have tried doing a sketch inside the assembly, then making the sketch for the door just be equal size to that sketch. This does allow me to move the door as I want, but when I try to update something then it really blows up.
