Hi Niels,
I'm not sure exactly what you mean by the rotation vector of a triangle? There
isn't really one as a triangle is defined by three points (9 components)
whereas
a rotation matrix/vector is defined by only 1 point (3 components). A general
matrix could be defined which maps a given triangle to the new triangle but
that
isn't really useful.

| What I mean is: In MLCad, you can take a part, and rotate it via a vector command like turn 45 degrees around y axis clockwise. Or more complex rotations based on more axes. What I would like to know is: How do I find the rotation vector of a plane (...) (19 years ago, 28-Nov-05, to lugnet.cad)
