Returns the data content of the ResBuf object as three-dimensional vector instance.

This method generates the OdError_InvalidResBuf exception when the stored data type does not correspond to the Point type. When the ResBuf object stores two-dimensional point or vector, this method converts it to the three-dimensional vector adding zero Z-coordinate.
