The lines 835-840 are extra. They involve calling to BRep_Tool::Curve, and the same call will be done in IsInvariant method.

Dear Mikhail,

I'm not sure that lines 835-840 are extra, because IsInvariant() will return a result for the edge without 3D curve based on invariance of its vertices. But the method HasShape() verifies if the edge has a geometrical entity.

In case of deciding lines 835-840 unuseful, we will still obtain exception on the second check:
