The resonant substructures of $B^0 \to \overline{D}^0 \pi^+\pi^$ decays are studied with the Dalitz plot technique. In this study a data sample corresponding to an integrated luminosity of 3.0 fb$^{1}$ of $pp$ collisions collected by the LHCb detector is used. The branching fraction of the $B^0 \to \overline{D}^0 \pi^+\pi^$ decay in the region $m(\overline{D}^0\pi^{\pm})>2.1$ GeV$/c^2$ is measured to be $(8.46 \pm 0.14 \pm 0.29 \pm 0.40) \times 10^{4}$, where the first uncertainty is statistical, the second is systematic and the last arises from the normalisation channel $B^0 \to D^*(2010)^\pi^+$. The $\pi^+\pi^$ Swave components are modelled with the Isobar and Kmatrix formalisms. Results of the Dalitz plot analyses using both models are presented. A resonant structure at $m(\overline{D}^0\pi^) \approx 2.8$ GeV$/c^{2}$ is confirmed and its spinparity is determined for the first time as $J^P = 3^$. The branching fraction, mass and width of this structure are determined together with those of the $D^*_0(2400)^$ and $D^*_2(2460)^$ resonances. The branching fractions of other $B^0 \to \overline{D}^0 h^0$ decay components with $h^0 \to \pi^+\pi^$ are also reported. Many of these branching fraction measurements are the most precise to date. The first observation of the decays $B^0 \to \overline{D}^0 f_0(500)$, $B^0 \to \overline{D}^0 f_0(980)$, $B^0 \to \overline{D}^0 \rho(1450)$, $B^0 \to D_3^*(2760)^ \pi^+$ and the first evidence of $B^0 \to \overline{D}^0 f_0(2020)$ are presented.
