Thanks, Kevan and Bob

So STL files are facets files. Output from CAD to RP or from reverse engineering to CAD or CAM.

But on doing reverse engineering we usually import clouds of points for surface reconstruction. I confirmed with our partners who also do reverse engineering, and they argue that this far, STL files result worse on surface reconstruction then the clouds of points.

If I could explain the reason why we and our partners work better directly over poins then STL to do build CAM or CAD files, opposite to you I wold be near to close my doubts.

Software we use is suposed to be worlds leader cam software, STRIM, from Matra Datavision. We also use Euclid 3 and newborn QUANTUM.

Best Regards Leonel
