Curtain Wall Grid

Hi @eirannejad thanks a lot for sending the stuff through! It works great when revit/rhino units are set to feet, but once I change the revit/rhino units to mm or meters, I am not able to generate any gridlines (first python component gives null values). Am I missing something really obvious here? I have jumped into the coding world just recently, so apologies for asking silly questions. Thanks again. Dan
