algorithmic modeling for Rhino
Hello,
I am trying to extend a curve via the rs.ExtendCurveLength()-function in Python and got it to work with regular Nurbs-Curves. The method looks somehow "dirty" to me; taking the Control-Points of the Curve and combine them with rs.AddCurve just to get a Curve with an id-number...
import rhinoscriptsyntax as rs
c_degree = rs.CurveDegree(Curve)
c_knots = rs.CurveKnotCount(Curve)
c_points = rs.CurvePoints(Curve)
c_neu = rs.AddCurve(c_points, c_degree)
#c_neu = rs.AddNurbsCurve(c_points, c_knots, c_degree)
ExtendedCurve = rs.ExtendCurveLength(c_neu, 0, 1, DeltaL)
C = ExtendedCurve
2 Problems:
- I don't get the rs.AddNurbsCurve() to work (says "runtime Error: len() of unsized object)")
- with rs.Addcurve() Arcs and PolyCurves are obviously not reproduced correctly
any ideas?

How about using Curve.Extend(CurveEnd.Start, deltaL, CurveExtensionStyle.Smooth)

Thank You David, that works perfectly!
import Rhino.Geometry as rg
C = Curve.Extend(rg.CurveEnd.Start, DeltaL, rg.CurveExtensionStyle.Line)
