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!!!!
