Fixed Wall Connection

[Anonymous]

I have a 9' high wall and a half wall, and I want them to be connected always. Is there a way to maintain their connection automatically whenever I stretch one of the walls?

Also, how can I define the position of the window so that it always stays in the middle of the wall it's on whenever I change the wall's length?

Thanks.

None of those options are available in AC.

The only intelligence ArchiCAD has here is that if you have Walls that form an L-connection (joining at their ends), then you can select both, in which case you will be able to edit them like segments of a polyline. In this case if you offset one Wall, the joining Wall's length will also change to follow and keep the L-connection.
Unfortunately this does not work with T- or X-connections.
