Offset of polysurface not trimming in rhino 7

[Nick14 (Nick)]

I have a polysurface that I am trying to offset. When I offset it inward it creates overlapping surfaces that are not consistent with the single polysuface and does not result in a solid. I upgraded to rhino7 and now the offset command doesnt have a trim.

In this situation is better to create a closed solid and then use the shell tool instead.
The offset uses surface direction to build the border and doesn’t consider the continuity between them.
