Hi,

I am a newcomer, using the Caeses to optimize  the bow of ship.But I don't know how to get the angle of waterline and buttock line， (Or how to get the angle between tow curves) and I want to know weather there is some feature can solve my problem.I would greatly appreciate it if anyone could provide assistance!!!

Hi Susan,

if you have a curve (which could also be the edge of a surface) you can "ask" the curve.gettan() with the corresponding arguments at which parameter value of the curve and in which plane, see below.
