If you search MathGroup for "3D locator", you will find several threads on this topic. Here's one: http://groups.google.com/group/comp.soft-sys.math.mathematica/browse_thread/thread/3f40635cfe3356d6/dd11ad46016b8475 The idea is to use MousePosition["Graphics3DBoxIntercepts"] to find out where a line perpendicular to the screen intersects the 3D bounding box. If you are only interested in 2D, take a look at Locator, or, in Mathematica 6.0.2, the "get coordinates" drawing tool accessible from Graphics -> Drawing tools (CTRL-D).
