I'm currently using "VW17" and the object is a curtain wall. yes, I did all that and got the walls ( Curtain wall) to show up, but the cells are not working correctly. I used the Worksheet Function to modify the "Database header cell" for thing like "Mark, Height, and wall thickness els........The whole worksheet (schedules) should use its base language for operations and needs to be reworked to be easier to use in general.
