I created a salad server spoon using meshes (my first go with meshes). The wood spoon will mount in a hollow silver handle so I need a smooth flare on the handle ending with a clean unrounded edge. From that edge there will be a smaller tang projecting into the handle. I'm trying to attach a picture of the spoon I'll be replicating. To do the proper flare, the only way I know to do it was to have a section beyond the part to maintain. I'd like to convert the stl to a solid so I can cut it with a plane, then attach an extruded tang to this flat end. I get an error message that there are too many facets to do the conversion from mesh to solid. I'm using ViaCAD Pro 14. Would Power Pack enable me to do this? Or upgrading to Shark?

Don't you need Subdivision to Nurbs first to use Meshes for Solids? Otherwise you have to many facets when it should look round without NURBS.
But Subdivision to Nurbs was removed in newer versions.

Thanks for the response. I'm not sure what you mean by Subdivision to Nurbs. Is it a tool? The only one I know is the Subdivision tool on the Mesh pallet. I'm over my head working with meshes on this project but I knew that what I usually did with Solids wouldn't work here. Is it part of Power Pack?

Mesh solidification has been limited to fewer than 3K faces since around V7, but mesh booleans have been improved since V11/V12, it might work to subtract a very thin mesh box to separate the pieces instead of slicing with a zero-thickness plane, model your additions/extensions as meshes, model in solids and convert them to mesh objects once you're satisfied with them and add or subtract them back in. .stl wasn't intended to be an editable format, better to keep your mesh originals to work with and export as .stl when you need it.

I fooled around a bit with it myself and found that the best way to split the object IMO is to enclose part within a *mesh* box with one side the split line, copy object and box in place, subtract the box from one copy, intersect the box with the other, giving the two parts split at the box face.
