TIG,
Your POINTS CLOUD TRIANGULATION package is GREAT, thank you for advice! I have just checked it recently and it is probably the only solution that works well for cpoints triangulation.
I do not understand though how cloud_71 relates to your solution (or probably it doesn't relate at all). I tried it while importing .ply into SU and it was not great unless a point cloud is planar. But it works sometimes

.
I am sure for you it is not a big deal to shovel any point cloud of any format into SU, but for me it was hard! This is why I referenced this link. It is easy if the original point cloud is in xyz type format, but I get the scanned point cloud from my3dscanner.com as Standford .ply. with RGB color, etc.
Anyway, thank you a lot!
You mentioned there are better solutions to import point clouds in SU. I am interested in importing .ply point clouds into SU. Can you please mention few?
In exchange I do not ask you even more stupid questions of how to import COLOR point clouds - I've read those threads:)
