| | Summary | 0023591: IGES Boundary Entity containing Composite Curve fails to translate. | | Description | When IGES Boundary Entity contains a Composite Curve with rank number of >= 2 (in the list of its model and/or parametric space curves), the exception is thrown. This happens because ShapeExtend_WireData objects, named Gsewd[2d/3d] in IGESControl_IGESBoundary::Transfer(), accumulating results of translation of a current curve, will contain disconnected TopoDS_Wire(s). Before returning, the method will try to add these ShapeExtend_WireData objects to previous results calling ShapeAlgo::AlgoContainer()->ConnectNextWire(), which underneath calls TopExp::Vertices() on TopoDS_Wire. Given that the wire(s) is(are) disconnected, the returned vertices are null causing an exception in BRep_Tool::Pnt() which is used to find the best orientation of a wire.
The fix is to call ShapeFix_Wire::FixConnected() for wires which were produced from curves of >=2 segments. This will only be applied to Boundary Entity and EdgeList, while Curve On Surface will remain unchanged. | | Steps To Reproduce | igesbrep VZ-387.igs v

Without a fix no shape is created and there is a failure recorded.
With the fix, the shape is created and no failures are recorded.
