Place a cased opening

Use the Opening tool for cased archways and pass-throughs — a wall hole with trim, no door slab, no glass.

The Opening tool drops a cased pass-through onto a wall — a doorway-sized hole with optional trim but no door slab, no swing, and no glass. Use it for archways between living spaces, kitchen-to-dining cutouts, or any wall void that doesn't need a door.

Before you start

Draw at least one wall in the room. See Draw a wall.

Steps (desktop)

  1. Click the Door / Window / Opening button in the left toolbar, or press O. If the button shows the door or window icon, click once to activate that variant, then click again to open the flyout and pick Opening.
  2. Hover over a wall. A ghost outline previews where the opening will land.
  3. Click the wall where the opening should sit. The Add Opening dialog opens.
  4. Pick a Width preset (the door presets — 24", 28", 30", 32", 36" — are shared since cased openings are usually doorway-sized) or type a custom width.
  5. Optionally type a Trim width per side. Set this when the project's casing or jamb depth should show on the plan.
  6. Pick a Header Height preset (78", 80", 84", 96") or type a custom header height. This is the top of the opening relative to the finished floor.
  7. Tap Place.

The values become the Opening tool's next-time defaults.

Fast path — Shift+click to skip the dialog

Hold Shift and click another wall to drop a second cased opening with the same defaults.

Steps (mobile / tablet)

  1. Tap the Door / Window / Opening button in the left toolbar.
  2. Long-press the button to open the variant flyout and tap Opening.
  3. Tap a wall where the opening should sit. The Add Opening dialog opens.
  4. Pick width and header height, then tap Place.

What makes an Opening different from a Door

Aspect Door Opening
Slab Yes — a door panel with a hinge No — empty hole through the wall
Swing Yes — four directions No
Arc on plan Optional None
Use Bedrooms, bathrooms, closets, exterior doors Archways, pass-throughs, cased openings

See Opening types reference for a side-by-side of all three opening types.

Tips

  • Cased openings render with the trim outlined on both sides of the wall void, so the casing depth still shows on the plan even though there's no door.
  • A cased opening with a 0" trim renders as a clean wall void — useful for unframed pass-throughs between rooms in a single open layout.
  • Cased openings can't be flagged as exterior. The placement dialog has no Exterior toggle for cased openings, so they're treated as interior by convention — for an exterior pass-through, use a door or window instead.
  • For every field available after placement, see Entity panel. On mobile, see Opening edit panel (mobile).
