How can I create a stepped foundation?
One application for pony walls is a stepped foundation. The lower part of the pony wall is the concrete wall with footing, and the upper part of the pony wall is a framed wall built to the first floor platform.
It's not recommended that the following steps be performed on walls that are not set to be Pony walls, as gaps can easily appear between floors. If you need to reset the top or bottom heights of a modified wall, open the wall in question up to specification, click on the Structure panel, check the Default Wall Top/Bottom Height box, and then click OK to confirm the change.
If you wish to turn off the setting that makes Chief Architect select the room before the wall, navigate to Edit> Preferences and on the Architectural panel, remove the check next to Select Room Before Wall in 3D.
