A cross section of the process e+ e\u2212 \u2192 \u03c0 + \u03c0 \u2212 \u03c0 + \u03c0 \u2212 has been measured using an integrated luminosity of 17 pb^{-1} collected with the CMD-3 detector in the center-of-mass energy range 650-1000 MeV. The main goal of this analysis is precise measurement of the cross section.
