From new precise data of the modern experiments, it becomes clear that the pure isobar model works only qualitatively and not able to describe the data in presence of many inelastic channels. The final state interactions modify the shape of isobars and produce additional structures on the Dalitz plot as well as on the 3 particles mass distribution. The first order correction to the isobar model is the triangle diagram. We discuss the effects of the rescattering on the several examples: $3\pi$ final state, $J/\Psi\,p\,K$ final state and $J/\Psi\,\pi\,\pi$ final state. Modern technique for data analysis with the unitarity constraint is presented.
