DS Explorer V12.0.1
My design has several NPN power transistors in the TO3 package. For these I created custom components using NPNTRAN and TO3 package from the the DS libraries. I specified the package connections as "3,4" for the schematic collector pin.
This causes a DRC NC error because I cannot route a board track between pads 3 and 4 on a 2 layer board with a conductive aluminium heatsink covering the top layer.
I belatedly read the manual, edit the custom component, and change the "3,4" to "3+4" to signify "internally connected".
No matter what I do - update package, update component, forward design changes - I cannot force this change through to the PCB design. I still get NC errors from a DRC check.
How do I force the "internally connected" specification to actually work?
