Ok, you all (I hope) know of 3D Studio MAX. On how they have 4 views, top, side, front and perspective. And you know how they click on CUBE and then click on the top view, that'd start the cube on the top view etc.. Well I just wanna figure out HOW to figure out that point. So say they click in the middle of the box (the front view) they'd get the X=0 and the Y=0. If they moved the mouse over one unit to the right, the X=1. So the question is, how do I figure out the X and Y points of where the mouse clicked. (btw, not the x and y pixel co-ordinates, the 3dim co-ordinates). I hope you get what I mean
