Video: Create Tapered Walls

Create a tapered wall.

This video demonstrates the following:

1. Edit a Wall type so it has a variable layer.
2. Set the default slant angles.
3. Place a wall and set the cross section to tapered.
4. Override the type angle settings with instance angle settings.

Tapered walls are created by specifying a variable layer and angles for the interior and/or exterior faces of the wall.

To create a tapered wall, start with a wall with a vertical cross section. The Cross- Section instance parameter controls whether a wall is vertical, slanted, or tapered. Before a wall can use the tapered cross section, you must first specify a variable layer in the wall structure. With a wall selected, click Edit Type on the Properties Palette.

In the Type Properties dialog, click Edit next to the Structure parameter. In the Edit Assembly dialog, choose one of the wall layers to be variable. This is the layer that will change thickness when a tapered cross section is selected. Only one layer can be set as variable. In this example, the EIFS layer will be variable. Click OK.

When a variable layer defined to the wall structure, Cross Section Properties are visible in the Type Properties dialog. Taper angles can be defined to the wall type. These angles will be applied by default when the cross section of the wall is set to tapered. In this example, set the exterior angle to 2 degrees. The interior angle will remain at 0. Specify where the width of the wall is measured. In this example, we will keep it at the top. Click OK.

To create a tapered wall, on the Properties Palette, select tapered for the Cross-Section. The 2 degree angle is added to the exterior wall face. Select Override Type Properties and assign different angles to the wall faces. Positive angles will cause the face to taper toward the top of the wall, negative values will cause the face to taper toward the bottom of the wall.

When working with tapered walls, you may specify angles that will cause the variable layer to become 0. If this happens, a warning will display. Change the angle, the height, or where the wall width is measured.

Use tapered walls in your model when you have the conditions where they are required instead of using generic models or walls modified with sweeps and reveals.
