The efficiency and accuracy of the method diffracted Gaussian beam analysis (DGBA) has been validated by the commercial software GRASP, but the deficiency that it is only capable of analyzing 2D symmetrical quasi-optical systems limits its applications. In this paper, an extension to the 2D DGBA software is made to make it capable of analyzing 3D asymmetrical quasi-optical systems. And the results have been validated by the commercial software GRASP. The 3D software seems flexible and easy in designing 3D quasi-optical systems.
