ac3d get_selected_surface

[thierry_st_malo]

There are a number of really useful scripts I could produce, given a new ac3d command, called for instance "get_selected_surface". This command would deal with the currently selected surface (one surface at a time) and return a Tcl list, like so:

{ <name> <id> <type> <n> {x1 y1 z1} {x2 y2 z2} ... {xn yn zn} }

Is it possible?
Given that, I could, for instance, easily answer Tartarooga's request for a "new extrude", create Coons surfaces, etc.
Cheers,
Thierry
