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](/user-manual/rhino-plugin/pollination-commands/alphabetically/po_resetboundarycondition.md), which will reset all interior surface to outdoor or ground condition. {% embed url="" %}
