Not sure if its a bug or I'm doing something wrong, but I have created a component with a PCB symbol that contains an odd shaped pad. That shape is on the copper layer and associated with a small pad (for the connection point). Now, if I do a GenCAD export, I don't get the copper shape in my .cad file ! I only get the pad and padstack information for the small pad. I'm currently using v19.0.4. Any clues ? anyone ...
