solid vs polysuperfice

[Sadsu]

Hello everyone, it's not much that I use rhino and I'm going crazy in an attempt to figure out how to turn a polysuperfice into a solid.
I tried to take a look on the internet and on various forums, but I can't get over it.

Until the polysurface is closed, it might look like a solid, but I wonder if it really is. If I send the file in 3d printing what do I print? a solid inside or a polysurface and in the latter case with which thickness of the edge?

My problem is actually more complex. I have a polysuperfice and I want to split it up. But when I split it appears to me as an empty polysurface inside, I could also close it by extruding the base, but the doubt remains. What do I have? a solid or a polysurface?

I would also need to drill the polysurface that I would actually like to be a solid, but at the most I can pierce only the edges of the surface.

Is there a command to transform polysurface into solid?

thank you so much for the attention

rhino does not work with solids, yours are polysuperfici.

if you have to print in 3d you have no problem because you turn it into stl then the printer "sees" it as solid.

to drill the polysurfaces you must extrude the curve and with that surface cut what you need.

You can also use Boolean operations, shorten your work. But you must have worked well before, if the polysuperficies are open you may have difficulty in doing so.

sadsu, you don't have to worry.
when you realize a tightly closed polysurface, you automatically have a solid. a solid means that that model is printable in 3d. both the nurbs with which rhino works and the polygonal solids with which other cads work are internally "empty". You don't have to worry about this. to "fill them" you do not use cad but cam in poor words, choose whether to make your full model in 3d printing phase using another program, usually care or slic3r.

I hope I have solved your doubts.

Thank you so much to both of you.
in case you don't want it full and want it empty inside, the thickness you decide in cad or cam?

 

[TECNOMODEL]

the thickness you have to create in the model by making an offset of the surfaces and cutting everything.

create your closed polysurface and you will notice if in the mass properties the volume does not give you any notice then execute the mesh command create the mesh and save in stl.the thickness the filling and the filling plot will be managed by the cam
