How can you extrude surfaces alongside axis xy/xyz? extrudesrf is stuck to the z axis

Here is a video

the first example is done in maya, and shows what I do mean
while the second part is done on rhino, extrudesrf, seems to be stuck in the z axis

on rhino is there a way to do the same thing?

In Rhino, this is done with the _OffsetSrf command.

For SubD, Rhino has an option to extrude faces along their normal but the result is just the extruded surfaces not including the original surfaces. There’s also a _OffsetSubD command which has an option to create solids.
