levigazione mesh

[Japs]

Hello everyone, I'm just hoping that I'm just adventured in 3d design with autocad 2015.
I created a solid through revolution of a polylinea transformed into a region. the problem is that the curved edges of this solid are jagged, as a circle made of low resolution. the autodesk guide says I should have the option sanding in the property table, but I do not see it.
It is a problem that I only have in realistic view but it resolves if imposed wireframe, however if I go out in stl and open it with windows 3d viewer always gives me the jagged edges.
Can someone recommend solutions? ?

sincerely I don't use autocad to design in 3d and I don't think it's the right tool... You could use fusion 360 that has a free license for personal use or sketchup to use something amateur.
the problem I think is in the definition of mesh in which export the stl file. I don't know that command. However try to look if you can set some data in exporting to stl.
