# PO\_SetAirBoundariesByGuides

Use this command to set rooms' interior surface to air boundary type based on guide surfaces.

Notes:

* Guide surfaces have to be coplanar to target interior surfaces and fully cover the interior surface geometries.
* It requires adjacencies to be already solved before using. So run PO\_SolveAdjacency first before using this command.
