I have C-code at work to solve this, even if the lines are not co-planar. It
calculates one point on each line (the 'nearest points'), and if they are the
same, the lines are co-planar. Mail me at ai@cej.se if you want it in a hurry,
here at home I only download news during evenings (= your mid-day??).

| If I have two co-planar lines in 3-space, does anyone know how I can determine their intersection? If it makes the equations easier, the plane that they are in is: Z = 1 - X - Y otherwise written X + Y + Z = 1 Anyone? --Travis Cobbs (...) (24 years ago, 13-Sep-00, to lugnet.cad.dev)
