Nope. it all just blew up/crashed

Did an stl to stp in Alibre 2.5MB to 43MB PRT file (Alibre STP)

saved from Alibre to IGS 137MB
(MOI couldn't open Step Sat files or they took ages)

opened in MOI and saved as a 3DM 287MB

It's a messy subject matter area of work IMO but the ability of MOI to draw inside the scan makes it far more practical

I think my earlier work to get the 20MB file involved mesh reduction in MESHLAB and faffing about with that
MESHLAB is a good program, like MOI it's tightly written and very efficient

edit: I just remembered, if you can get the STL under 1MB then life gets a lot easier.

Hi Ado, I'm not surprised there are problems. The MOI Sub-d importer is not intended to be used on high density scan data with hundreds of thousands of triangles. It's designed to process a sub-d control cage made with a few thousand quad faces.
