fmeobjects.FMEGeometryTools.closeCurve3D

FMEGeometryTools.closeCurve3D(curve, mode)

This function closes the curve in 3D if it is not already closed. If the curve is not 3D, it forces the curve to be 3D with default z value of 0.0. A closed curve is defined as one where the start and end points are equal in all X, Y and Z coordinates. The returned geometry may or may not be the original object that was passed in. If None is passed in, nothing will be done and None will be returned. If a different object is returned, the original object will be destroyed. There are 3 modes that the function uses in deciding how to close the curve, namely FME_CLOSE_3D_EXTEND_MODE, FME_CLOSE_3D_AVERAGE_MODE and FME_CLOSE_3D_EXTEND_OR_AVERAGE_Z_MODE.

  • In FME_CLOSE_3D_AVERAGE_MODE, the curve is closed by modifying the current start and end points of the curve to be the average of the two points.
  • In FME_CLOSE_3D_EXTEND_MODE, this method will add a straight segment from the end point to the start point to force the curve closed.
  • In FME_CLOSE_3D_EXTEND_OR_AVERAGE_Z_MODE, the curve is closed using the AVERAGE mode if the start and end points only differ in Z. Otherwise, the EXTEND MODE is used.
Parameters:
  • curve (FMECurve) – The curve to close.
  • mode (int) – The FME_CloseCurve3DMode.
Return type:

FMECurve or None
Returns:

The closed curve. Note: This method returns a terminal geometry type of the FMECurve; i.e. one of the leaf classes in the FMECurve inheritance graph. For example, a FMEPath is returned if the geometry truly is a path.
Raises:

FMEException – An exception is raised if an error occurred.
