Windows and 
Doors
Windows and doors can be positioned freely in all views 
. On input, their reference points can be changed using ‘Ctrl+w’, and of course the construction aids can also be used. The software automatically recognizes in views / sections the first visible wall within the depth of the section, and offers the element for insertion here. In 3D views, the wall in which the window or door is being positioned appears transparent, to allow a view of the rooms and furnishings behind it.
