Can someone please help me with a Fixed Window over an Awning window. I can't seem to find the correct 3D representation for the opening lines for this part. The standard library has a few that are close but oddly none for this common option. I don't know enough about GDL to modify one. I can see the gs_opline_3D parameter but can't figure out how to get to what I want.
I'm using the standard v10 Library.
