      | :c:enum:`~A3DStatus` A3DSurfIsDegenerated(*const* :c:type:`~A3DSurfBase`\ \* **pSurf**\ , *const* :c:struct:`~A3DVector2dData`\ \* **pUVParameter**\ , :c:type:`~A3DDouble` **dTolerance**\ , :c:type:`~A3DBool`\ \* **pbIsDegenerated**\ , :c:type:`~A3DBool`\ \* **pbUDirection**\ )
   
   Function to determine if a surface is degenerated at a point.
   
   **Parameters**
   
   
      **pSurf**\ : The input surface.
   
      **pUVParameter**\ : The coordinates of the point.
   
      **dTolerance**\ : The tolerance of the test.
   
      **pbIsDegenerated**\ : The returned value.
   
      **pbUDirection**\ : The direction of the degeneracy if a degeneracy is detected (true = U direction, and false = V direction).
   
   
   **Returns**
   
   
      ``A3D_SUCCESS``\ on success, or an error code on failure
