It would be nice to have an additional Coordinate tool for isometric constructions.

If I'm working on an isometric drawing I have to design my things with x, y, z coordinates.
Y is, of course not a problem but for x and z I have most off the time to work with construction lines for move, copy, locate etc.
With an isometric coordinate snap tool what will follow the 30° angles for x and z we could save a lot of construction lines ;-)
