hi,
it appears that the nurbs surfaces returned for cylinders and cones are not marked as rational. the weights are right, just not the rational flags.
also, when the surface is a cone, the apex cvs aren't in the right place - they are on a unit circle around the apex.
thanks,
lowell
thanks for info.
these are dd bugs. we'll try to fix it in next release.
