Regular operation of the VEPP-2000 electron-positron collider started at the end of 2010 and about 60 pb−1 were collected so far by the CMD-3 detector in the whole available c.m. energy range from 0.32 GeV to 2.0 GeV. One of the main goals of the experiments at VEPP-2000 is a sub-percent measurement of the e+e− → π+π− cross-section. Here we present the overview of the data analysis techniques and the preliminary results of this measurement.
