Offset srf not working well

[davide76]

I started with a SubD surface (on the right), used the “radiate” command and converted the entire shape to Nurbs.
Then I wanted to give thickness to that shape through the “Offset Srf” command but it doesn’t thicken well.

Avoid tangent surface corners. This is not good for offsetting. With creased corners you get a better offset result, then later blend the edges. e.g.:

depending on your needs- if you are shelling for a 3d print,

shrinkwrap is a superhero for this process.

Rhino 8 windows- never fail shelling with Shrinkwrap (new feature!)

This should work. Like @Gijs said the corners are the problem. I opened RH-87128 to get to the bottom of it.

Thanks Joshua.
