How do I even calculate time?
I’d get a reliable clock.
DistanceTo seems to be tiny little bit faster (on rhino 6).
Even it it was vice versa, I would still use DistanceTo, as it is more readable.
import Rhino import time pt1 = Rhino.Geometry.Point3d(10,20,0) pt2 = Rhino.Geometry.Point3d(200,100,0) t1 = time.time() for i in xrange(100000): dist1 = (pt2-pt1).Length t2 = time.time() for i in xrange(100000): dist2 = pt1.DistanceTo(pt2) t3 = time.time() print ("t2: ", t2-t1) print ("t3: ", t3-t2)
