# Solve Adjacency Solve adjacency (command: [PO\_SolveAdjacency](https://docs.pollination.solutions/user-manual/rhino-plugin/pollination-commands/alphabetically/po_solveadjacency)) is used for setting up interior surfaces. Users can select a partial of rooms or entire model for solving adjacencies. The existing interior surface will not be changed to outdoor boundary condition, and it will be updated when a new adjacent surface is found. Users can also have an option to reset all surface's boundary conditions by using command [PO\_ResetBoundaryCondition](https://docs.pollination.solutions/user-manual/rhino-plugin/pollination-commands/alphabetically/po_resetboundarycondition), which will reset all interior surface to outdoor or ground condition. {% embed url="" %}
