I am designing a plan with thick exterior walls and very deep windows as a result. How do I control where the frame and sash are inset within the window frame?
A home that employs thick wall types, such as straw bale, brick, rammed earth, or logs, may 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 wall, 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 frame.
When this box is checked, the frame Depth automatically extends from the Recessed Into Wall layer to the wall's inside surface with an Inset of 0". The Recessed Into Wall layer is specified on the Options panel of this same dialog.
