Hi,
I just upgraded from Rhino 5 to 6.
For the command surface offset (OffsetSrf) why is there no option to offset it in both sides? Rhino 5 has it and is very useful command sometimes.
I might have turned it off accidentally, if so how to turn in back on in Rhino 6?

Is it possible that you have selected a Polysurface instead of a Surface?
Well on the right in properties it says extrusion. This I tried opening the model in rhino 5 and the offset worked just fine.
very strange.
I have uploaded the model as well.

I think that OffsetSrf isn’t working because your extrusion is comprised by two parts, thus making it a Polysurface and not eligible to the Both Sides option of the command.
why is both for polysurfaces missing?
I don’t know why, but would you need it?
of course yes
i often extrude a bunch of curves, polylines then offset and boolean union the result, which is faster than to offset curves both directions clean up the mess or make curve boolean or whatever and then to extrude. but when there is a polyline in the game it becomes a polysurface and ruins the play, the option both suddenly is not available.
here in the sample below the outer closed polyline i can get away with by using slab, but it is a bit confusing having to think of it and also a bit of a flow breaker. it often slips my mind since its not a command i frequently use and it would be nice to have an option just to extrude all the curves and polylines and then offset surfaces and polysurfaces at the same time in both directions.
that is probably a very simple case… and i mainly just wondered what keeps the both option shy when a polysurface shows up.
thanks, I added RH-76346 OffsetSrf both sides is missing for Polysurfaces
