anyone uses "SIMetrics"for the spice simulation?

-how to measure distortion of amplifier?
-how to measure frequency caracteristics (Fmin, Fmax (-3dB))?

You can look at distortion with Probe - Fourier - Probe Voltage Quick

I don't use it but many spice capabilities are the same - try to find furier and AC analysis (the latter may also be called 'Bode Plot'). Fourier will give you a hamonic analysis and usually a distortion figure, AC/Bode will give you the amplitude and/or phase response.
