Rhino issue: solid modeling

[obscurejack]

Hello!

I'm a noob in rhino and I found some problems by making a polysurface solid:

my problem is that I have two elements: a sphere and a twisted pyramid, joined by boolean union which I can't offset to add an internal thicken.

when I do it (with "solid" option activated) it just creates a polysurface inside it, without creating an emptiness in it. I can't even make a boolean difference, boolean 2 objects or neither a solid subtraction that work with polysurfaces which surfaces do not intersect each other.

Indeed, when I make a section to see how it is inside there's no hole but only the sectioned edges of the offset polysurf.

H E L P!!!!

Rhino has a surface focus. Thus, some of the concepts that pertain to "Solids" in other software applications are not present in Rhino. One such concept is internal hollows - or, put another way - surfaces/surface incorporation without direct connection.

 

 

The typical way to deal with this is to add a direct connection. See attached image. I was able to hollow out that figure by providing a minimal direct connection in an inconspicuous spot.

thank you very much, I already solved the problem with the same tecnique but in a different way ^^

I already solved the problem . . . . ^^

That's all that matters.
