I have an object which i have 3D scanned and imported into rhino. The file is an .stl file. Rhino reads it as a mesh and i have succesfully converted it into a polysurface. Now i want to be able to edit the form but muy problem is that the form consist of 171392 polysurfaces, so its rather large and makes my pc stall. Further more its quite impossible to edit an object consisting og that many small surfaces. Its a cubic shape made up of ca. 30 facets, so i really need to simplify the polysurface form from 171392 surfaces to just 30. Is there anyway i can do that??
