Hello,
How do I get the Length of a selected Spline?

I found this code...but it seems not to give me the length.
Anybody can help me here?

var defaultSpline = doc->GetActiveObject();
var realspline= defaultSpline->GetRealSpline();
var sldata=realspline(SplineLengthData);

Thank you.

It's a bit cumbersum in pre R12 as PointObject splines
and Primitiv splines are treated different.
All sorted to the better in R12.021+

Cheers

// R11.5 and lower   
var splinetype = op->GetType();   
if(splinetype == 5101) // PointObject Spline   
    {   
     if(!op->InitLength(0))   
        op->InitLength(0);   
     println(op->GetLength());   
     println("PointSpline");   
     return;   
    }   
  
if(splinetype > 5101 && splinetype < 5190) // Primitiv Spline   
    {   
     var prim = op->GetSplineObject();   
        prim->InitLength(0);   
     println(prim->GetLength());   
     println("PrimitivSpline");   
     return;   
     }   
println("Not a Spline");

  
// R12.021+ Get length of any spline   
if(!op || !op->GetRealSpline()) return;   
var rs = op->GetRealSpline();   
var sld   = new(SplineLengthData);   
    sld->Init(rs,0);   
var splinelength = sld->GetLength();   
  
println(splinelength);   
sld->Free();
