WARNING!
I just updated a few bytes of the file.
Script now works in 2012, 2013 versions.
I do not have the source and I can not change anything in the script.
Some functions may not work.

The original file: http://www.creativecrash.com/maya/downloads/scripts-plugins/polygon/c/zhcg_polytools--2
Owner: cg zh

demo videos: http://www.youku.com/playlist_show/id_4488599.html

install:
1. copy zhcg_polyTools.pyc to your scripts folder.
2. add codes below to your userSetup.mel
(in "My Documents\maya\your version\scripts" dir, if not exists, just create one):
python("import zhcg_polyTools;zhcg_polyTools.build_ZhCG_PolyToolsMenu()");
3. then the "zhcg_polyTools" menu appeared in maya main menuBar.

* "Spin" based on "SpinFaces.mel" by Giuseppe Improta.
* "ShrinkWrap" based on "XYShrinkWrap.mel" by Imre Tuske.
