    I am trying to design a PCB board using ORCAD PSpice.I have the footprints of all other components except those of LM317 and LM7812 since they are not available with the PSpice.
    Where should i look for these so that i can proceed with the design?

    That will be TO-220 package. http://en.wikipedia.org/wiki/TO-220 Which I am sure the Orcad system has as a footprint. You will not find a ECAD system that has all components in the library. So making your own symbols and linking them to a footprint. Is something you must master. Very often you can make the job simple by using a similar existing component as template. I do not use Orcad my self. But I am sure if you use Google. You can find some tutorials
