I think this is the checkbox that you are looking for.
It is located in the "Compatibility Options" Dialog of the "Details" page of the GDL Editor.
I didn't think of looking in there.
Anyway, I have figured out that I do not need this function. Creating my own WALLHOLE with all edges off overrides any overlapping WALLHOLE 3D contours created by the GS objects.
Yes if you can script your own wallholes, you will have better control.
Actually you can use a wallnice - one facing externally and the other facing internally.
Then you can control the pens and materials separately for each.
And I have taken it one step further with an option for 2 wallniches externally so I can have an adjustable split in the materials to match complex profile walls with different materials.
