The Curve from BRepAdaptor allows to use a Wire of the BRep topology like a 3D curve. Warning: With this class of curve, C0 and C1 continuities are not assumed. So be careful with some algorithm! Please note that BRepAdaptor_CompCurve cannot be periodic curve at all (even if it contains single periodic edge).

The Curve from BRepAdaptor allows to use a Wire of the BRep topology like a 3D curve. Warning: With this class of curve, C0 and C1 continuities are not assumed. So be careful with some algorithm! Please note that BRepAdaptor_CompCurve cannot be periodic curve at all (even if it contains single periodic edge).
BRepAdaptor_CompCurve can only work on valid wires where all edges are connected to each other to make a chain.
