Switcher CAD III

Does anyone know how to produce a Bode plot with this software?

I can produce oscilloscope traces, but not a Bode plot. My attempt at a BP resulted in a horizontal line at about -300dB. But the circuit I was simulating has a voltage gain of 10, so the BP should be 20dB in mid range.

Any assistance will be appreciated.

Use AC analysis. Simulate>edit simulation cmd>AC analysis.
For the source, Advanced>small signal AC analysis = 1
Also look at posts etc here
