I am wondering how the reference planes in the Curtain Wall Door Family Template are connected to the extents of the curtain panel in a project - as there are no width or height parameters indicated. The OOTB curtain wall doors seem to "magically" adjust themselves to the size of the curtain wall panel.
The reason I'm wondering is I want to modify the way the door appears in plan so that it shows some thickness, but I'm not sure how to assign a dimension or parameter to my new symbolic lines, so that the width of the panel swinging out is the same as the width of the curtain wall panel in the project.
A similar problem arises when I try to assign a parameter to the swing angle.
I hope I explained my issue clearly. Thank you for your help.
