Returns the data content of the ResBuf object as two-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 three-dimensional point or vector, this method converts it to the two-dimensional vector truncating Z-coordinate.
