The process e+e− → ωπ0 → π+π−π0π0 was studied in the energy range between 1 and 2 GeV to the best precision in the world. The data used correspond to an integrated luminosity of 35pb-1 accumulated with the SND detector at the VEPP-2000 e+e− collider. The statistical accuracy of the measured cross section is 2 to 22%, whereas the systematic uncertainty is 2.6 to 14%. The present results agree with the results of earlier measurements but have a better precision.
