A window belongs to a wall, as a door does. You give its position along the wall, its size and the height of its sill.

Before you start

Your building has the room room-walls from Draw a wall.

Add the window

The centre of this window is 4.5 metres from the first point of the wall. The bottom of the glass is 0.9 metres above the base of the wall.

Rules

  • offset, width, height and sillHeight are in metres.
  • sillHeight is the only vertical control of a window. A window has no baseHeight.
  • The top of the window, with its frame, must be below the top of the wall.
  • The window must not overlap a different opening in the same wall.

Move or remove the window

A window uses the same commands as a door: move-hosted-opening and remove-hosted-opening. See Add a door.

A hole with no window

To cut a plain hole, write a void in the model. A void is an entry in the openings of the wall, with kind: 'void', an offset, a width and a height. See Change the document.
