I would like to edit the shape of my windows. How can I accomplish this in Home Designer Pro?


In Home Designer Pro, any non-symbol, fixed glass window can have its shape customized.

Editing the shape of a window

  1. Select Build> Window> Window  and click in the wall to place it.

  2. Select the Window, and click on the Open Object   edit tool to display the Window Specification dialog.

  3. On the Shape panel, use the options to adjust the shape of your window. You will notice that as you make changes, the preview of the cabinet in the dialog updates, as shown in the example below.

    The Match Roof button has the program match the angle of the top of the window to the pitch of the roof on a gable end. The window maintains the angle even when resized and re-positioned.

    A window that has been modified using the Shape panel cannot have divided lites or shutters added in the Window Specification dialog.

  4. The Arch panel also allows you to adjust the shape of a window.

    The settings located on the Shape panel take precedence and will override any properties set on the Arch panel. You may also notice that the settings on the Arch panel will be grayed out and inaccessible if modifications have been made on the Shape panel.

  5. If the window is placed in a curved wall, use the Casing panel to access the following options for how the casing is built in the wall:

     - Both window sash and casing are straight. Straight casing may not fit properly into a wall if the window is too wide or the curvature of the wall, too tight.  


     - The sides of the casing or jambs are inserted in the wall at an angle that passes through the center of the curve. 

     - The sides of the casing are inserted in the wall at a right angle to the line tangent to the curved wall at the center of the window. 

    Normally, parallel casing has a straight sash. Radial casing is more like traditional curved windows, and typically has a curved sash.
