If you use Schematics, you can create a part in the Symbol Wizard. In
Schematics, go to File/Edit Library. In the Symbol Editor that comes
up, go to Part/Symbol Wizard, select the From a Model Library, and
follow all the steps.
The important thing to remember is you can only add so many parts in a
symbol library in the student version of Schematics, IIRC about 20, so
only have the models for the parts you need. A lot of the vendor
libraries have a lot more than this. You can cut and paste the
necessary models using a text editor.
The reason for two front ends is a matter of taste and style.
Schematics is the old MicroSim front end, which is nicely optimized for
PSpice. Many of us old users find it more convenient and efficent.
Capture has much better ties to PCB layout packages, and is more
versatile in some ways. Also, all the new development is focused on
Capture, so it is suspected that Schematics will someday (probably some
time in the far future, Jim) disappear.
Hope this helps answer you questions...
