Hi,
What is the simplest method of finding the perpendicular angle / direction of the below beam (red arrow)
I used this :
!GenDirPerp = !!ce.zdir.orthogonal(!!ce.plstart.nar.direction(!!ce.plstart.nal))
But with this method I don't know if it's going to give me the up or down version of the direction. If I swap nar / nal I get the opposite, but I still don't know which one it will return. I specifically need to know which one it will return
Thanks
