Recessed Windows

[ARCHIJEF2000]

I’ve decide to cut my last reply completely, and try again. I’m including a new image, with the casing, and a couple of screen shots. The wall I used has three layers. The outside layer is 150 mm, and the following two are 250 and 10 mm. Make sure layer no. 2 is defined as the main layer.( under define walls, click radio button 2.)It’s the thick outer layer that enables you window to go in and sit on the second layer. Make sure all your windows are blocked together properly, if not this method will not work. Although it will work for a single window.

I think this is what you want.
Use these settings




Final post script: I've done some checking , an it seems the recessed box under options, will be greyed out, if a single layed wall is used, I am sure this is the real reason it would not work for you, to summarise, use more than one layer. let me know if this works for you.
