What are the different ways to create a bay, bow or box window?


Bay, bow and box windows can be created either automatically or manually. This article will describe both methods.

To create a bay, box, or bow window automatically

  1. From the menu, select Build> Window> Bay Window , Box Window  or Bow Window .

  2. Once you have made your selection, click once on a wall in which you would like to add the window. A window of the type you selected will be created at that location.

Note: A component window within a bay, box or bow window can be resized like any other standard window. To select a component window, click at the location of the component in question, then click the Select Next Object  edit button or press the Tab key on your keyboard.

  • Only the bay or box window component that was clicked on is selected using this method. If you need to select a different component, click on it and repeat the process.
  • In a bow window, all components are identical, so only one component can be selected. Changing this component changes them all.

To create a bay, box, or bow window manually

Bay, box, and bow windows can also be created manually using walls and standard windows.

  1. To create a bay/box/bow window, draw three or more additional walls to the size specification that you would like the window to be.

  2. From the menu, choose Build> Wall> Exterior Wall  and draw the walls for the bay/box/bow window in a clockwise manner.

  3. Once the additional walls are in place, you will be able to add windows by selecting Build> Window> Window  from the menu, and clicking in the wall where you would like to place the window.

After you have placed a window in each wall, you will want to make the bay/box/bow window accessible from the rest of the structure. The easiest way to do this is to make the wall that currently exists between the window and the interior of the home invisible. Naturally, you will not want to make the entire wall invisible, but you will want to make the small segment that separates the box window from the rest of the room invisible.

To mark the wall section invisible

  1. From the menu select Build> Wall> Break Wall .

    You will be able to click on the wall segment and break it. It is be best to place a wall break on either side of the three wall bump out.

  2. Once the wall segment has been separated from the rest of the wall, click the Select Objects  button and double-click on the wall segment to open the Wall Specification dialog.

    • On the General panel, place a check in the box beside Invisible and click OK to close the dialog and apply the change.

  3. Take note of the fact that the three walls of the box window, and the invisible wall combine to form a complete room. If you again click on the Select Objects  tool, and then double click in the middle of the box window room, the Room Specification dialog will display, and the values for Floor Height and Ceiling can be changed to alter the height of the box window as necessary.
