Place doors + windows in 3D
Click a wall, drop a door or window, set width/height/sill. Diaz cuts the opening, adds a lintel, and remembers the swing direction.
Quick answer
- Select a wall in 3D view. Toolbar → Door or Window.
- Set width, height, sill (windows). Click on the wall to place.
- Right-click → Swing direction for doors to flip LH/RH.
Step-by-step
- Switch to 3D view if you are not there yet (
View → 3D, or shortcut3). Select the wall you want to add an opening to — it highlights mint-green. - Pick the tool:
Toolbar → DoororToolbar → Window. The inspector shows the default dimensions — 880×2010 mm for an interior door, 1800×1200 mm for a kitchen window. Adjust width and height before placing. - For windows: set the sill height. The default is 900 mm above floor level for living rooms. Set 1100 mm for kitchen counters (over a backsplash) or 0 mm for floor-to-ceiling glass. The value sticks for the next window you place on the same floor.
- Click on the selected wall to place. Diaz automatically cuts the opening through both faces of the wall and adds a lintel above (default 100 mm steel angle for openings >1500 mm; reinforced concrete for wider). Lintel material is set in
Settings → Structure → Lintels. - For doors: set swing direction. Right-click the placed door → Swing direction → pick LH (left-hand), RH (right-hand), LH-reverse, or RH-reverse. The 2D plan shows the swing arc; the 3D view shows the door open at 30° as a reference.
- Slide the opening along the wall: click the door/window and drag horizontally. Diaz snaps to wall-thirds (1/3, 1/2, 2/3) and to a configurable offset from corners (default 100 mm) so doors never end up flush against a corner stud.
Watch out
- Swing direction wrong on plan: LH vs RH conventions differ per country. In NL/EU, looking from the room you are entering, "LH" means hinges on the left. Verify by checking the 2D arc — clients usually find errors here before the contractor does.
- Sill 900 mm default in bathrooms is too low: for privacy, set 1500 mm or higher in bathrooms. The default is fine for living and bedrooms, but Diaz does not auto-adjust by room type. Set the sill per window.
- Lintel auto-add overrides custom structural detail: if your architect specified a different lintel (e.g. timber instead of steel), the auto-add still places the default. Right-click the opening → Lintel → Custom to override per opening.
