I'm not worried about disk space so much as I am worried about render/move/edit
time. Unnecessary polygons, even after being read in and converted into internal
models, take time to process. I think you can see the difference in POVray
render times, for example... even if the part was compact on disk because it
uses nested submodels, it might blow out to a lot of polygons that need
clipping/raytracing/texturemapping and thus slow down render time.
So:
* Things that cause artifacts - very bad
* Things that add polygons that don't add to the image quality - bad
* Things that add polygons that do add quality - it depends, probably good
(especially if you can turn them off for fast renders when doing tests)
IMHO anyway. YMMV
(is this FUT right? shouldn't this be in CAD somewhere. moved it to lugnet.cat)
