Other usage issues

Hi,

I'm looking for a API call that decomposes a spline into a set of arcs / line segments.
So far I haven't been able to find it... any ideas are much appreciated!

Thanks,

-jelle

Do you need circular/elliptical arcs ? what is the requirements on the result (tolerance or something else) ?

You can use SplitBSplineCurve to split up a spline in smaller segments at specified parameters.

You might also find GeomConvert_BSplineCurveKnotSplitting useful.

You can of course use value(p) to split up the curve into linear line segments.

Yes! GeomConvert_BSplineCurveKnotSplitting is what I've been looking for! Thanks Mikael
