Convert Polyline to Line Segments

[WonkaPet]

Hi there,

Does anyone know how I would go about converting a polyline to line segments.

This would be similar to when a Spline is converted to a Polyline using ToPolylineWithPrecision(false,false).

Unless you want special consideration of arc segments, the EXPLODE command will do this.  If arcs are present and you need segments along the arc, you will need a custom lisp or add-on to remove the arcs (and substitute short approximating segments).

Thanks for the response. I am currently using explode to get Arcs and Lines but I need the Arcs to be segmented out with a specific precision.

@WonkaPet 

// Arc approximation
double prec = 0.00001;
Arc arc = //... initialization of your arc
Cuve3d curv = arc.GetGeCurve();
Interval intl = curv.GetInterval();
double startParam = intl.LowerBound;
double endParam = intl.UpperBound;
PointOnCurve3d[] ptCurvs =
  curv.GetSamplePoints(startParam, endParam, prec);

The same possible to do with whole polyline.

@Alexander.Rivilis That solution worked thank you.
