Question about BrepAlgo_Section

Hello ,

i'm doing an intersection between a shape and a plane. I got in return a compound of edges. I use these Edges as parametric Geom_Curve, so I get the returning points. Anyway, I get many returning Curves even for a single Section-Path. And sometimes these are not connected.
Is it possible to get a single curve from a single "Section-Path"? Or : how can I merge many Geom_Curve to get a single one?

Thanks in advance!
