What Is Smart Flow Check? Catch Layout Problems Before They Happen | Room Sketch 3D

Smart Flow Check is Room Sketch 3D's always-on layout analyzer. It quietly checks your floor plan for overlapping furniture, recliners and sofa beds with no room to extend, door swings blocked by a piece, walkways narrower than a person can comfortably pass, cramped seating, and furniture blocking windows — then lists each problem with a one-line fix, updating live as you move things.
