Adding columns, radiators, and other obstacles

Mark the things you can't move — columns, radiators, ducts — so your furniture layout works around them.

Updated 2026-06-10

Columns, radiators, ductwork, and chimney breasts are obstacles — fixed elements furniture has to work around. Place them like any wall fixture and Smart Flow Check accounts for them.

Step by step

  1. 1

    Pillar (column)

    Build PanelPillar tile. Click, then click in the room where the column sits. Set size (4–24 inches diameter or square) and shape (round / square) in the Inspector. The pillar renders in 2D as a small filled shape and in 3D as a full-height column.

    A pillar dropped inside the room — furniture and Smart Flow Check work around it.
  2. 2

    Radiator

    Furnish Panel → Symbols → Radiator. Place against the wall. Standard residential: 24–48 inches wide × 6–8 inches deep × 18–30 tall.

  3. 3

    Other obstacles

    Ductwork, chimney breasts, built-in cabinetry, plumbing chases — model with the Pillar tile (sized accordingly) or as custom furniture (Furnish Panel → Custom Furniture).
