Hope this email finds you in good health.

I am using UCSF Chimeria for my de Novo drug design disseration.

I am still learning the basic functions that this software offers, however have not been able to figure out the following.

Basically I need to put into one picture/frame the original ligand or my receptor and the possible ligands (generated by Ligbuilder). They have the same general structure with some changes and I need to superimpose them, but show them at separate levels. Is this possible to do this for only the ligands and not the receptor protein? 

I eagerly await your reply,
