Hi Yasser,
Sorry, mutation with the Rotamers tool (or swapaa command) is only to  
L-amino acids.

Some less convenient alternatives:

- use Build Structure (under Tools... Structure Editing) to build out  
the D- side chain manually.  Note the resulting bond lengths and  
angles are approximate.

- open another structure that contains the D- amino acid, match the  
backbone atoms of the residue you wish to substitute, write out  
coordinates "relative to" the first structure, then manually edit the  
PDB file to substitute that sidechain for the one originally in the  

I hope this helps,
