Other usage issues

Geom_BSplineCurve BSC(Poles, knots, mults, Degree);

Handle(Geom_BSplineCurve) hCurve(&BSC);

BRepBuilderAPI_MakeEdge anEdge(hCurve);

const TopoDS_Edge &shape = anEdge.Edge();

I cant understand why this isn't work with error "Invalid address specified to RtlValidateHeap( 00000172A2F50000, 0000002D1691F4E0 )" when I'm trying to use vtk to write a Bsplinecurve.

If someone knows how to resolve these problems, please share your knowledge. Thanks very much!

ok I've found how to use handle which i should use 'new'.

Maybe you should use Handle(Geom_BSplineCurve) hCurve(new Geom_BSplineCurve(Poles, knots, mults, Degree));
