Hi
Rhino.Geometry.LineCurve(LineCurve) looks broken in SR7 … don’t know in SR8
this code says the second length is zero here
import Rhino
a = Rhino.Geometry.Point3d( 0, 0, 0 )
b = Rhino.Geometry.Point3d( 9, 9, 9 )
c = Rhino.Geometry.LineCurve( a, b )
d = Rhino.Geometry.LineCurve( c )
print c.GetLength()
print d.GetLength()
( Duplicate() works fine though )
Cheers
