About Changing the Roof Line and the Floor Line of a Wall

You can modify the roof and floor lines of a wall to create a non-rectangular wall.

You can also create non-rectangular roof and floor conditions by projecting to polylines.

AutoCAD Architecture 2025 toolset offers multiple methods of editing roof lines and floor lines. You may want to begin by graphically creating a custom roof line or floor line condition. You can then fine-tune that condition by specifying precise values in the Roof/Floor Line worksheet on the Properties palette.
