Hi Sheelam,

There are multiple approaches used commonly to effect exterior/interior courtyards with the eQuest wizards, chosen by preference of the modeler. For unconditioned (exterior) courtyards, I find the shell "cutting method" most intuitive. Attached are a few past discussions that include illustrations of the concept. These and many more similar discussions reside in the mailing list archives.

I encourage you to subscribe and post directly to the mailing list in the future: equest-users at lists.onebuilding.org - I'm merely one of many contributors and you'll often find addressing a larger body conducive to a quicker response. The other advantage is you can get a representation of many perspectives that way as well, and no single individual has all the answers =).

Best of luck for your endeavors!
