I am designing a plan with thick exterior walls and very deep windows as a result. How to I control where the frame and sash are inset within the window frame?


A home that employs a very thick wall type, such as straw bale, rammed earth or logs, will have very deep windows. In Chief Architect, you can specify the Inset value for a window's frame to control whether it is located near the exterior of the frame, near the interior, or at the center.  

Similarly, you can control the inset of the sash, the portion of the window which actually frames the glass, relative to the exterior edge of the window frame.

To control a window's frame inset

  1. Open the Chief Architect plan in which you would like to change the inset of a window.  

  2. Using the Select Objects  tool, click on a window to select it and click on the Open Object  button to display its Specification dialog.  

  3. On the Frame panel of the Window Specification dialog:  

    • Uncheck the option "Fit Frame to Wall" and specify a custom value for the Inset of the frame.  

    • The Inset value for the frame is the distance of the outside surface of the frame from the outside surface of the wall.  

    • The Inset value for the sash is the distance of the sash from the outside of the window frame of which can be edited on the Sash panel of this same dialog. 

      Be sure to remove the (D), which stands for default, or the program will keep the default value regardless of your change. 

  4. When you are satisfied with the Frame and Sash Inset values, click OK to close the dialog and apply your change.

  5. To see the results in 3D, select 3D> Create Perspective View> Full Camera  from the menu, then click and drag a camera arrow towards the wall.
