Hi Bala,
Command "fitmap" has a huge number of options, both local optimization and global search, and you could of course do more fitting starting from any current fit.  

You can also always save the fit by saving the PDB files in their positions relative to the map model.  The fitted PDBs and the original map model could be input to any other program that fits coordinates into maps. There is a "Save PDB" button on the fit list from global search

...or you could just use the regular PDB-saving approaches in Chimera as mentioned here:
