Macro for planes

Does anyone have a macro to share that will put a plane half way
between two selected parallel planes or surfaces? If not, is this
possible with macros?

 

I have no macro but if you hold down the CTRL key & drag any existing plane
it will copy & default to offset distance place. but then you just change
it to paralell at a point & choose the midpoint

There is also the midsurface command that will create a surface at the
middle between two selected faces. if the surfaces are flat this would be
just like createing a plane.

Hope that helps
