    Smile Intersecting Lines in 3D

    Hi all,

    If you look at the pic below I have two lines in 3D that pass over each other. I want to calculate the point shown by the blue cross. This is halfway between the two lines in the z axis.

    When the two lines cross they have the same x and y values but not z.

    The vectors that describe the lines are...

    Line 1: 154.21x - 437.83y - 1.46z
    Line 2: -190.44x -351.4y - 15.7z

    Is this possible? I would be very grateful for some help, thanks
