Hello! Revolve just outputs to solids or subds.
What’s the best way to get a mesh out of it? My workaround is creating a solid with the desired PointCount, then ‘ExtractControlPolygon’.
Any better options?
Cheers!
The Mesh command?

Thanks!
Using Mesh on the revolved solid gives something like this:
But I need something clean, like this:
your workaround is a good one- I’d stick with that.
you can revolve with a subd output, then export that control polygon, but its about the same amount of steps.

Ok, thanks!
There are some flaws in this, however:
Maybe consider adding ‘clean’ mesh output to Revolve? Should be kind of straightforward.
that’s an odd output…
can you post the file with the curve you used?

Is this a possible alternative?
I understand if you do not like this route, but it seems nicer to work in the sectors you are clearly wanting here.
Here’s the file:
test revolve.3dm (46.0 KB)
Strange indeed, because suddenly it looks ok. I don’t really understand why it didn’t before.
Thanks! That’s possible of course, but you know, a lot of clicks.
I wouldn’t have thought that something seeming so trivial is a bit of a challenge in Rhino.
I guess meshing must be a generalised approach, which is optimised for general manifolds(?), rather than specific types of geometry like this.
However, perhaps a future feature request should be for the creation of meshes of revolution, where the sector can be defined either in terms of a density, or by brute forcing some fixed sector angle.
I think that Blender and 3DS Max have this type of option. This is Spin in Blender, if I recall:
https://docs.blender.org/manual/en/latest/modeling/meshes/tools/spin.html
We could use this sort of thing in Rhino for such instances.
explode your curve, then run rebuild with 2 points, and check the “subd friendly” option
then join the curve and revolve.
extract control polygon
the only upside of this workflow (workaround) is you can edit the subd easily before you extract the control polygon.
