computing the normal of a curve fails ( using BRepLProp_CLProps | GeomLProp_CLProps )

Hi,

Something puzzling; of a planar curve, I can compute its tangent, but not its normal, if I try to do so, a LProp_NotDefined is raised.
I'm sure that the parameter is within scope, and also I initialized the *LProp_CLProps with a resolution of 1e-6, and maximum degree of 4.
Perhaps someone could enlighten me why no normal is returned, or did I stumble upon a bug?

Thanks,

-jelle

Likewise. Anybody?

Same for me. It crash when trying to compute the Normal vector of a TopoDS_Edge.

I face the same problem while computing curvature using BRepLProp_CLProps. The program crash after some where in between by dumping :

1 -0
terminate called after throwing an instance of 'LProp_NotDefined'

Any idea!

Would you help if you solve the problem!

Regards

Game
