Hi - The SVN version has been modified to support this: give it a try.

No. I'd by happy to integrate any contributions adding such a feature.
>    THIRDLY, is there any method to draw different 2D lines in ONE diagram, which is useful to compare different them? I know GMSH can draw different different 2D lines in different view[], but they are in different diagrams. I also googled an example: http://www.uker.net/Article/UploadFiles/200704/20070420114003542.bmp

Same thing.
