You can use the advanced configuration properties of the Fold feature to fold a piece along an internal line. For example, you might want to add a fold to a collar.
To use the advanced fold configuration properties:
If there is no suitable internal line, use the Pen tool to add an internal line to the piece where you want the fold to be.
On the Main toolbar, click Select.
On the Horizontal contextual menu, ensure Internal is selected.
In the 2D window, select the line where you want the fold.
In the Context view, in the Line Properties section, select Fold. Fold properties and advanced fold configuration properties are displayed.
Type a value for each of the properties as required:
If you use the advanced fold configuration properties, the fold type displays as Custom.
Prepare Angle -A number from 0 (no fold) to 180 (piece folded directly against itself). This property determines the angle that the piece is folded to before simulation. It is recommended to set this close to the Fold Angle value, but not the same value.
Fold Angle - A number from 0 (no fold) to 160 (piece folded almost directly against itself). This property determines the angle that the piece is folded to during simulation, taking account of fabric physics, collision, and other external forces.
Softness - A number from 0 to 100 determining the softness of the fold edge. The higher the number, the softer the fold.
Layer Offset - A number from 0 to 100 determining the offset between two edges of a folded piece that meet, to prevent collisions.
