Hi yannada, well some good news!

I was able to make a few strategic fixes to the geometry library which helps surface offsetting out quite a bit.

Both of your examples, the G2/G3 filleted box and the chair will work in the next v2 beta and you won't have to scale your chair down in size to do the offset in the next beta.

Danny, that other chair that you linked to will also work but it seems to have a tiny fold in the tip of it so that area is a bit messy when offset.

But it looks like a pretty significant step forward in this area for the next beta.
