Hello,

I am using OCC for meshing BRep Models. Can someone tell what is expected results of first Derivative ( on a curve ). Should it give normalized values or unnormalized values ?

Thanks.

It would be always better to call the gp_Vec::Normalize/Normalized method to ensure any vector to be Unit.
