 I assume the point cloud was created by scan data? Whoever generated the
data probably has the file on hand and could generate another format for
you, or, you can surface directly from the point cloud in Imageware without
having to create an STL first. If your end result is CNC, the person who
scanned the object should have the file on hand in which you can go directly
to that. Some scanner software will let you do basic CAD work such as punch
holes, trim, etc. right to the scan data so it might eliminate a step.

Imageware has one of the better packages on the market to deal with point cloud.
