—Calculates the wall width using offset dimensions from the attachment edge.
1. Select a trim option for both sides of the attachment edge:

—Trims or extends the wall end from the chain end by the value specified. Type a value in the box or drag the handle in the graphics window.
◦ ![](../../../sheetmetal/sheetmetaldesign/images/twist_wall_start_width_centered.png)
—Calculates and centers wall width from the twist axis by the specified dimension.
1. To change the start width, type a value in the
![](../../../sheetmetal/sheetmetaldesign/images/value.png)
box.
2. To locate the twist axis on a datum point, click
![](../../../sheetmetal/sheetmetaldesign/images/twist_wall_axis_location.png)
and select a datum point on the attachment edge . This is the centerline of the twist wall. It is perpendicular to the start edge and coplanar with the existing wall.
| When you twist the material into a spiral, keep in mind that the wall will fail if the material bends through itself. |
4. Use the drag handles in the graphics window or type a value in the box and press ENTER for each of the following dimensions:
◦ ![](../../../sheetmetal/sheetmetaldesign/images/twist_wall_end_width_value.png)
—Width at the end of the twist wall.
◦ ![](../../../sheetmetal/sheetmetaldesign/images/twist_wall_length.png)
—Length of the twist wall, measured from the attachment edge to the end of the twist axis.
◦ ![](../../../sheetmetal/sheetmetaldesign/images/smt_bend_angle.png)
—Angle/rotation of the twist wall.
5. To change the wall length in the unbent state, perform the following steps:
a. Click Bend Allowance. The Bend Allowance tab opens.
b. Choose a value form the list or type a new value for the Wall length in an unbent state in the box.
