Hi everyone, I wanted to do a conversion test in NURBS surfaces this 3D scan(https://www.thingiverse.com/thing:1415162), I used Blender to generate the square topology with the remesh modifier, then I exported to OBJ and I created a new mesh using a free app Instant_Mesh to generate a smaller file 21.9MB (21.882.962 bytes), finally I imported in Moi3D to generate the NURBS surface from the square mesh obj model, the conversion was successful but the resulting file is huge, unmanageable, to be used too heavy 1.6GB (1.564.648.052 byte)

Below the zip file contain the file use for the NURBS conversion.
