Hi,
1. did you use any library window?
2. Did you draw a new window using slab, roofs, ecc.?
3. Did you write any GDL code?
1. If yes, it showld be a parameter to control number of panels
2. If yes, you can't add panes and HS to make it parametric
3. If yes, you can make all parametric (HS included using an array)
Regards
Marco
