Bay and corner bay windows add interior alcoves and panoramic glass to a room. Both place in two clicks; the bay auto-carves the wall it's placed on.

Step by step

  1. 1

    Pick the type

    Build Panel → Windows section. Click Bay Window (one wall) or Corner Bay Window (two walls).

  2. 2

    Click the wall (or corner)

    Bay: Click the wall where the bay projects. Corner Bay: Click the corner where the bay wraps two walls.

  3. 3

    Set width and projection

    Inspector → Width (length along the wall — typically 60–120 inches for bay). Projection (how far it pushes out — 16–36 inches).

  4. 4

    Verify in 3D

    Switch to 3D. The bay renders with the alcove inside and the protrusion outside. Walk through it to confirm.
