[GRASS-user] problem whit "map is 3D"

[Benjamin Ducke]

As I understand, v.edit is currently pretty much 2D only.

As far as I am concerned, it would be great
if v.edit could do some _basic_ 3D manipulations.
I'd love to have the ability to swap coordinate
values freely between axes and the attribute table,
so that I can turn a X/Y/Z map into X/Y+HEIGHT or
vice versa.

Another great feature would be the ability to rotate
points around a freely-definable axis in 3D space
(maybe better to add this to v.transform, though?).

If I had those, I could un-install my CAD applications
right now ;)

I know that there is probably no-one with enough
free time on their hands to implement these things
right now, but maybe we could just think how to best
design them and who knows, sooner or later some-one
might get around to implementing them.
