non-rectangular windows

[J Luckner]

Hi - I need to model several  fixed trapezoidal windows; is this possible  using WINDOW? If not is there another option - Thanks!

Hi,

You can develop a spreadsheet with area weighting for non-rectangular geometries.  Another option would be to create an equivalent rectangular window that has average of the two sides of the trapezoid. That should give a very close answer, unless there is a huge difference between the sill and head framing sections. Normally, differences are only nominal, so this approach should be nearly identical with actual product area-weighting.

Thank you for the suggestions. Area-weight calc seems like way to go . Here's  an image of the windows in question:

W11, the tilted rectangle in the middle, is rough;y 4'x 8'.  Will the tilt make  a significant difference in the performance of the actual window?

Also - i'm new to this - i can't figure out how to override the defaults and enter the "actual" (adjusted) dimensions in the window library. 
How can i do that?

Thanks

Hi Jim,

Tilt will make some difference, but this is not handled by window. The closest approximation is to assume that it is not tilted.

You can make changes to dimensions if you chose olne of custom sizes. See below...
