    Importing Gerbers into ADIX

    Hey guys, I am trying to import my PCB design into Zeland for the purpose of patch antenna design. This process seems to take forever (never ending). Is this because my design is too complex i.e., it has too many vertices? Does it usually take long to import something? To give you guys an idea...
