Revision 2016-08-23 15:53 by msv
Description BRepTools_WireExplorer gives different number of edges in dependance of order of
edges in wire.(following OCC21771)

Draw command "checkshape" gives the different results in dependence of order of
edges.
Draw[9]> restore badf.brep f1
f1
Draw[10]> small
Draw[11]> fit
Draw[12]> donly f1
f1
Draw[13]> fit
Draw[14]> restore badf2.brep f2
f2
Draw[15]> display f2
Draw[16]> fit
Draw[17]> checkshape f1
On Shape faulty_1 :
BRepCheck_UnorientableShape
Shape faulty_2 on shape faulty_1 :
BRepCheck_NotClosed

Faulty shapes in variables faulty_1 to faulty_2


Draw[18]> checkshape f2
This shape seems to be valid

Shapes from file badf.brep and badf2.brep differ only by order of edges.
