To Create a Twisted Segment
1. Click Model > Shapes > Twist. The TWIST tab opens.
2. Select an attachment edge. The selected edge is displayed in the Placement collector.
3. Select a segment width option and follow the steps for the selected option.
◦ —Calculates the segment width using offset dimensions from the attachment edge.
1. Select a trim option for both sides of the attachment edge:
▪ —Sets the segment end at the chain end.
▪ —Trims or extends the segment end from the chain end by the value specified. Type a value in the box or drag the handle in the graphics window.
◦ —Calculates and centers segment width from the twist axis by the specified dimension.
1. To change the start width, type a value in the box.
2. To locate the twist axis on a datum point, click and select a datum point on the attachment edge . This is the centerline of the twist segment. It is perpendicular to the start edge and coplanar with the existing segment.
 
* When you twist the material into a spiral, keep in mind that the segment 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:
◦ —Width at the end of the twist segment.
◦ —Length of the twist segment, measured from the attachment edge to the end of the twist axis.
◦ —Angle/rotation of the twist segment.
5. To change the segment 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.
6. Click .
