how create a ".cir" file in Orcad 16.3

Hello, 

I would like to create a "cir." file in Orcad 16.3 but I'm a little lost, is that you can help me? 

is and what you can tell me how to change the number of output bipolar transistors, ie, I find in the software transistors 3 terminals (EBC), while I want to add the substrate channel but I do not know how. and when I change the netlest and I run the simulation it removes all the changes I did. 

Thank you for your help.
