To replicate the edge of a garment being folded over one or more times, you can add a fold to the edge of a piece using the force multiplier for edges feature.
The force multiplier properties of an edge are:
Amount - number of real-life folded layers of the fabric
Depth - depth of the fold
For example, if your real-life garment requires the fabric be folded 4 times, to a depth of 1 cm, to achieve the desired strength:
Set Amount to 4.
Set Depth to 1.
To use force multiplier:
On the Main toolbar, click Select.
Note: On the Horizontal contextual menu, ensure Pieces is selected.
In the 2D window, select the edge you want to fold.
In the Context view, in the Edge Properties section, select Force Multiplier. The force multiplier properties are displayed.
VStitcher 8.0 and newer VStitcher 7.9 and older
Type the values you want for Amount and Depth.
