GGU-CANTILEVER: Definition of cantilever wall
The cantilever wall is defined via the menu item "Editor 1/Wall (geometry)". The graphics visualise all necessary input.

You can use the "Thickness (bottom) for vertical air-side wall" button to determine the required "Thickness (bottom) du" for an inclined wall. Starting from the upper left corner of the angled cantilever wall, the program extends the air-side wall downwards to determine the lower wall thickness.
