Hello Old Grey,
I understand. May be from a systematic point of view the perfboard/stripboard rather belongs into the PCB view.
However, I like that photo realistic appearance in the BB view. It's ideal for compiling instructables which is my intention.
O.k. for the moment I can live with the current workarounds. Thanks so far. In case of potential further findings/developments I will mention them in that thread.
Best Regards
Albert
