  Re: Smooth surfaces
 
My thought was that the smoothing could be turned on and off, as appropriate. That would require metastatements in the parts files. Extra metastatements will slow down processing, but not by very much. They will also increase file size, but again, (...) (23 years ago, 24-Sep-01, to lugnet.cad.ray)
 
  Re: Smooth surfaces
 
Instead of shoving all these metastatements into files, maybe a file conversion utility (DAT -> POV) should keep an INI file that records which parts can be processed in this way, and which cannot. I'm basing this suggestion on the assumption that (...) (23 years ago, 22-Sep-01, to lugnet.cad.ray)
