Using this tool, we click at the wall on the desired location of the window. The window now becomes a part of the wall and the wall hatching automatically breaks around the window. If we move the window along the wall, the hatching adjusts itself accordingly. If we move or rotate the wall, the window moves or rotates with it. We will now perform a similar operation with the Door tool.
Doors behave in a similar manner to windows.
For some further external touches, we will add balcony balustrades. There are several ways to do this. At any time we may construct elevations of, and sections through, the building. We will set these so that the section lines may be seen on the plans, but elevation lines will not. We are able to change our building model in the elevation windows.
