Hi!

how can i calculate the angle between two points?

my math and trigonometry is rusty! ;)

thanks!

Can you use ATAN2? Something like:
angle# = ATan2(x1-x2,y1-y2)

thanks!

Actually it's ATan2(dy , dx) where dy = y2 - y1 and dx = x2 - x1, or ATan(dy / dx)

In fact ATAN2 is a good example of Bmax Vs B3D doc.
I'm guessing they work the same.

It gets worse. Trust me, in just a couple of years, you'll be wishing everything was as easy as trigonometry.
