API: Examining Warpage deflection for Flatness

For a warped part like this you may be interested to know the flatness of all points around the rim (marked with yellow arrows).

A script was created to get this information. It reports the flatness both before and after warp:

ISO Standard 1101 defines flatness as the minimum offset between two parallel planes (in any arbitrary direction) which enclose all selected points.

Workflow:

1^st. select nodes. The nodes can be on any arbitrary plane – they do not need to be aligned with the X,Y or Z axes. (Tip: you can save a selection list to make repeating this easier).

2^nd. Run the script

The selected nodes are assumed to be planar before deflection. The outcome is independent of the anchor plane defined.

This script works for Midplane, DD and 3D. It works for small or large deflection analyses.
