I have created multi solids within this part projecting geometry off the derived part from the frame assembly.
If I change the frame generator sketch parameters, then open the dervied part. It updates fine and the multi solids stretch out as required.
My problem starts when i close both files and then reopen. Then change the frame generator sketch then open the derived part. Some plate profiles become sick. I need to edit the extrusions for the sketches to update.
