Hm. For the first one, I have no idea.
For the second, you can add another Z axis with the AXIS function, but
I see no way to suppress a single axis in the original SURFACE call.
Are the axes in a SURFACE object themselves AXIS objects? If so, then
being able to access their properties with surface.axis.property would
be extremely useful.
