Default Saucers in Rocksim?

Hey Everyone,
Is there any way to design a simple saucer in Rocksim or OpenRocket? I have some students working on a project and they need to find the CG and CP of a 3-sided balsa flying saucer they are building with a central 18 mm motor tube. Is there another way to find the CG and CP of a saucer?
Thanks for any help you can provide.

Check out Bruce Levinson's articles about Rocksim in Apogee's newsletters:

Specifically, he wrote about calculating the base drag of wide, short rockets in a three-part series starting in issue #154.
