The shape of  door, glazing and other surface structures can be edited when the user double clicks on the main structure that those structures belong.

Otherwise, at the building level or at the block level the user can select the main structure and then by right click on it, select the option "Edit openings/surfaces".

 

 

 

The front view of the main structure will be shown and the opening or the other surface structure will be highlighted when clicked. To start editing the geometry of the highlighted shape, simply click on the shape grips on the perimeter and drag them to the desired direction.
