Hi Tao Zhao,
Chimera does not do homology modeling directly, but it can connect to a web server running the Modeller program.  To use this feature, you would first need to go to the Modeller web site and sign up for  a license key <http://www.salilab.org/modeller/registration.html>  -- it is free for noncommercial use.

A full explanation of homology modeling is not feasible for this mailing list (there are probably several books and thousands of papers on this topic), but for a description of the Modeller interface in Chimera, see:

<http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/multalignviewer/modeller.html>
<http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/multalignviewer/modeller.html#comparative>

... and for more about how to get the input ready... it sounds like you are "Starting with a structure already known to be a suitable template":
<http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/multalignviewer/multalignviewer.html#approaches>

There is also a tutorial, but be aware that it is only one example, and the process may be different depending on your protein of interest and what is known about it.

I hope this helps,
Elaine

P.S. better to send questions about using Chimera to chimera-users at cgl.ucsf.edu (CC'd on this message), not chimera-dev at cgl.ucsf.edu which is meant for programmers
