Hi!
I'm making a train track and I created a curve with X,Y and Z vectors. I would like to know what function would allow me to rotate the Y axis around the X axis and later use those vectors in a copy-to-point to place wood planks.

rotate vector around another vector (and use those vectors with a copy-to-point)? SOLVED!!

SOLVED!
Ok, so I already had my normals set in the direction of the path (in the image above, its the red vector). I also had the green vector that I wanted to pivot around the red one. for that, I had to do this vex code:

vector red = @N; vector green = set(0,1,0); float myRotation = chf("rotation"); matrix3 mRot = ident(); //picks up the current matrix rotate(mRot, myRotation, red); v@up = green; @up *= mRot;
