[Bldg-sim] CAD imports

[Dr. Nader Chalfoun]

You should also try to save the CAD file to older version of ACAD.  My
CAD 2007 is not compatible with eQUEST.

> I need help on CAD imports into eQUEST.   I would like to be able to

> eQUEST.  What are the prerequisites for importing CAD and not getting
> BDL or standard writing file error.  Recently I started a model, which
> was not drawn by me in CAD.  The zones weren't matching and when I tried
> to multiply floors, I got some serious issues.  Some walls disappeared.
> The floors were all off of each other.  Each time I tried to open or
> iterate the model more errors showed up.

> polygon and get the coordinates matched?  If one Cad floorplan is in a
> different part of the coordinate system than it's underlaying floor,
> what should you do?  Do you have to check some part of CAD coordinates,
> which I find perplexing.
