Since December 2010, the CMD-3 detector has collected data at the electron-positron collider VEPP- 2000. The sample of the accumulated data corresponds to about 60 pb−1 of integrated luminosity in the c.m. energy from 0.32 up to 2 GeV. Preliminary results of the analysis of various processes e+e− annihilation to hadrons are presented. It is shown the processes with multihadron events have several intermediate states which must be taken into account to correctly describe the angular and invariant mass distributions as well as cross section dependence versus energy.
