Since 2010 the CMD-3 detector has been collecting data at the VEPP-2000 e+e− collider. CMD-3 is a general purpose detector designed to study e+e− annihilation into hadrons in the center-of-mass (c.m.) energy range from 0.3 up to 2 GeV. Preliminary results for the e+e− → 2(π+π−π0) cross section were obtained in the c.m. energy range from 1.5 up to 2 GeV. The analysis is based on a data sample of 22 pb−1.
