Experiments with the CMD-3 detector at the VEPP-2000 electron–positron collider in the range of center of mass collision energies from 0.32 to 2 GeV have been performed since December 2010. The amount of accumulated data corresponds to an integrated luminosity of about 60 pb<sup>-1</sup>. The resultsof a preliminary analysis are presented for the following annihilation channels: e<sup>+</sup>e<sup>-</sup> → 3(π<sup>+</sup>π<sup>-</sup>), 2(π<sup>+</sup>π<sup>-</sup>π<sup>0</sup>), K<sup>+</sup>K<sup>-</sup>π<sup>+</sup>π<sup>-</sup>, K<sup>+</sup>K<sup>-</sup>, $$p\bar p$$, and π<sup>+</sup>π<sup>-</sup>. Since processes of electron–positron annihilation that involve the production of multihadron states proceed through several intermediate states, their analysis is necessary for the correct description of the emission-angle and invariant-mass distributions of product particles.
