Is it possible to convert several poly-surfaces into solids in Rhino3d.
Without seeing what kind of surface you are speaking about it is hard to answer. There are several on line utilities that will turn a nurbs surface into a solid .STL. Some surfaces will simply need to be capped..... no naked edges or bad geometry.
It is an inherited a 3d model of a sports arena and originally modeled in rhino. We are trying to convert several polysurfaces into solids in order to 3d print the model. The most difficult part has been the interior seating. The seats are all contained within 1 polysurface, which is comprised of nearly 1,500 individual surfaces. The seats are pretty standard are far as stadium seats are concerned.
select the poly-surfaces. This have to be intersecting surfaces and/or polysurfaces. They will be trim into a closed polysurfce.
then command: CreateSolid
or see menu solid=> Create Solid
