Create slanted walls and slanted curtain walls using the standard Wall tool. Slanted walls can host elements like doors, windows, electrical features, wall sweeps, and more.
When creating or modifying a wall, on the Properties palette, use the Cross-Section parameter to make it slanted. Then use the Angle from Vertical parameter to specify its angle from -90 to +90 degrees.
To insert doors and windows in slanted walls, use the Orientation parameter to orient the inserts vertically or aligned to the slant of the wall. This parameter can also adjust the orientation of sweeps and reveals for slanted walls.
This feature was suggested by customers on the Ideas forum and is described on the product road map.
