Hi there,  
so i’m fairly new to Dynamo for Civil 3d. I’ve already tried it in Revit before. So i created a very simple comand, that’s supposed to create circles based on the points read from an excel table. it seems to work in the dynamo space but when i try the dynamo player to actually create the circles in the civil 3d nothing is created. am i doing something wrong?
