Use the trim command...to set a vert on one of the lines at the intersection. To do this, you must attach the two lines into one shape. IF you wanted the original line to exist but just have a vert at the exact intersection, I drew a second line over the one that gets trimmed. Then I divided that line, make a vert exist on it, and then snapped that vert to the one created by trim. then some clean up.
I need to make a coordinate system align with the line that has the vert I wish to move...do that by snapping a tape helper to the line, and using pick in the drop down to create a coordinate system to use.
certainly fussier than rhino or autocad, but this isn't really what max does best.
