Excluding undercuts from clamp force calculation

If a model contains undercuts or slides, the projected area calculation of the clamp force may be over-predicted.

The analysis log will show a double projection of surfaces to the parting plane for these regions. This over-prediction causes the clamp force calculation to be overestimated.

1. Select the undercut elements.
2. Right-click any of the selected undercut elements and click Properties. The Part surface dialog appears.
3. Select the Exclude from clamp force calculation check box.
4. Click OK.
