Generates downskin contours based on the geometric difference between contours across one or more layers

| Parameter | Default value | Description |
|---|---|---|
| angle | Specifies the angle of the surfaces which are considered downskin. | |
| shrinkage | 0.4 | A filtering parameter that removes artifacts from the downskin detection. Downskin regions thinner than this setting (in mm) are not considered. |
| expansion | 0.6 | Downskin areas are expanded by a certain value in order to overlap neighboring layers. This value should be larger than the shrinkage. |
| thickness | 1 | Determines the range across which the angle is measured. Has an averaging effect. |
XML configuration example code:
<downskin name="my_downskin" entry="sphere" angle="40" thickness="1" />
