Thanks MO,

I applaud your development to Basic/Extract node....you have made it into a very useful and powerful tool, and in doing so reduced the bloat of the node library. We can now retire several nodes: Length, arraySort, FlipNumArray, stlArea, & perhaps also stlVolume.

There is an additional output from "stlVolume" node that may be incorporated in a future extended "Centroid" node (originally contributed by Brian/bemfarmer). Presently this node operates only on closed polygons. Ideally, it may be replaced with a universal "FindCenter" node that accepts both pt and obj data types: finding the centre of point arrays, curves (open & closed), surfaces, polysurfaces, groups of objects, and solids.

Returning to "Extract" node: there are 2 further functions that logically may fall within its scope ie "Shuffle", "Reverse" for point arrays (similarly to numArray options). If this is possible, we may retire 2 further existing nodes. See image

It heartens me that you've taken up the mantle and continue to refine nodeEditor.
