Hi everyone
I have a complex circuit which has some similar components, now I want to change all of one kind consider resistor R1, is there anyway to do this task except changing them one by one?

 

Don't understand. Change them into what? Why change them? You could try 2 by 2 or possibly 3 by 3 etc.

 

Is this a schematic or a physical circuit? If it's a schematic what software?

 

Thank u guys for reply!
I use orcad 16 (pspice).
It is a schematic circuit.
My circuit is composed of several sub-circuit which these sub-circuits are similar. for example, 1 have a 1kΩ resistor in one of these sub-circuits, now i want to change all of these 1kΩ into 3kΩ in all sub-circuits, is there any way?
if there is, how can i do this task?

 

If your sub-circuits (SC) are identical you could perhaps change R1 in one SC, delete all the other SCs, then copy/paste the first one?

 

Check to see if you can export the schematics to an ASCII format, such as EDIF, and then reimport them. If so, then you could use a text editor's search and replace capabilities. Ensuring that you ONLY change the ones you want might be easier said than done.
