Does having fewer polygons lower cost...if so, does using a hypernurbs object to smooth have any bearing on this... Thanks G
No, cost is based on volume (see the Materials page and note that all prices are per-cubic-cm, sometimes plus a fixed startup cost). SW doesn't accept anything over 500,000 triangles, and you can't make a 2-manifold (printable) object with fewer than four triangles, so those are the only polygon-related constraints you need to worry about.
