Create tapered walls as architectural, or structural walls to include in your design.
You can work with tapered walls in plan, elevation, section, 3D orthographic, and perspective views. See Place a Tapered Wall.
Create and modify tapered walls in much the same way as vertical walls. One layer in a wall's structure must be set as "variable" before the cross section can be set to tapered. See About Compound Walls. Angles for the wall faces may be set in the wall type properties. Angles from the wall type properties can be overridden for an individual wall in the wall instance properties.
Place a tapered wall as you would a vertical wall, then use the cross section instance parameter to select tapered. If angles for wall faces are defined in the wall's type properties the angles will be applied. To override the angles set in the type properties, select Override Type Properties and set the override angles using the Exterior Angle and Interior Angle parameters.
