[BLDG-SIM] cad/modeling interface

eQUEST is the best that I am aware of. You can import an AutoCAD drawing and trace it using the mouse. It is far from perfect and only works in 2-D (floorplans), but I have used it successfully on some fairly complicated buildings. It's a whole lot better than doing it manually.

eQUEST expanded allowable vertices to 120 in version 3-35, but there was a problem with the DOE-2.2 calculation engine and lots of vertices. There is a version 3-37 on the download site dated yesterday. Hopefully, the vertices problem is fixed.

General question for the list:

What is the latest progress and developments on the subject of integrating architectural CAD drawings of building shell into hourly energy modeling programs like DOE2 or EPlus?

Are there software interfaces out there that have gotten this down to a usable product, or are we still a few years out?

What are the obstacles to implementing this? Any success stories that people care to share? Any specific products that people have used?

Thanks!
