Every time I try to change the settings for a particular part of the cabinet I then lose the part editor cuts for the left and right panels. It even lost the kd/rta holes as well as drawer slide associations and hinge holes. I had to wait to cut the hutch curve in the left and right partitions until everything else was done. In order to get the hole associations back, I went and reapplied the hole associations to get them back.
Something seems really wrong with this cabinet, but I can't figure it out.
I have an assembly that does the same thing. If I select one of the cabinets in the assembly and open construction settings then exit, I lose all the part editor cuts.
Mine are on an assembly I brought forward from version 5 and that may be the problem.
I am going to redo the part editor cuts in Version 5 and see if they stick.
