The problem is that on the problematic face projection of first point of 3d curve on surface yields wrong result. The effect is that pcurve has a big loop, and whole face is invalid. (Note that in current development version the face is "valid" for checkshape and shading is OK when seen from the top, but the loop is still present and can be seen at the bottom of the shape). |

Hi Ding, with the current code version from the git repository (28.08.2012) the imported shape is valid and seems to be properly visualized. Can you please check? |

|
Hi Pawel, I am sorry, and I don't know how to verify it. But I promise I will verify it after OCC6.6.0 released. Thanks. |

|
Andrey, please add a test case for this issue to check that it has been fixed (I could not reproduce the problem on current master, too). |
