1Overview
The Problem

If you have ever attempted to design a custom window assembly with an arched top, you know how problematic this task can be in AutoCAD Architecture.  Assemblies, windows grouped together, typically have to be assigned as Infills within a Door/Window Assembly (DWA) but using a standard Window Object won't work when the shape of the assembly is Arched.

In the illustration to the right I show how standard Window Objects do not conform to the shape of DWA's.

In the discussion below, I will run through the basic steps required to build a custom Curtain Wall Unit Style that you can use as an Infill in your custom Door/Window Assembly Styles.

2Body
Build a basic Curtain Wall Unit Style

You can access the Curtain Wall Unit Style dialog, illustrated to the right, by typing "CwUnitStyle".

On my example Curtain Wall Unit Style, right, notice that I have set the Default Division to "Fixed Number of Cells" with a "Number of Cells" as 1.  This will provide a single rectangular shape but you can expand on this information and build far more complicated styles that have Muntins.

Define the Infill

In the illustration to the right, I renamed the Default Infill to "Glass" and set the Panel Thickness to 1/4".  You may also want to go to the Materials tab and set this element to a glazing material.

Define the Frame

In the illustration to the right, I renamed the Default Frame to "Sash" and set a Width and Depth.  I am calling the Frame element a Sash because this unit will eventually sit inside a Door/Window Assembly that will act as the Frame. 

Assign the custom Curtain Wall Unit Style as a DWA Infill

After completing the work discussed above, you can now use this custom Curtain Wall Unit Style as an Infill in your custom Door/Window Assembly Style.

In the illustration to the right I show that I have gone to the Infills section of my custom DWA Style and changed the name of the Default Infill to "Window".  Under the Style section I opened up the "Curtain Wall Unit Styles" folder so I could select my "Generic Window" Curtain Wall Unit Style.

3Conclusion
The Finished Product

The completed product should yield a DWA whose shape and proportions can change as you see fit while producing plausible windows.

In the illustration to the left I show an example of what I have cooked up for a new product that I hope to release in 2008: Openings 9.0 eKit.
