shrug-l: Problems with DWG 2007 Files in ArcGIS 9.1

Thanks for the heads up.  Just downloaded that converter.
On the same subject, if anyone out there has the occasional need to edit CAD
files, but doesn't need the full power of AutoCAD, there is a new version of
TurboCAD, called TurboCAD Deluxe V12, by IMSI, which will allow you to do
some basic editing of CAD files before bringing them into ArcGIS.  I think
the price tag is around $99 at discount stores (Office Depot).  This sure
beats any AutoDesk software, with AutoCAD LT now starting at $899.
I talked to IMSI about the DWG file version issues and they told me that they
keep updating their file reading capabilities and make the patches available
on their website.  TurboCAD will also read Microstation file formats (I think
they're DGN???).

Subject: shrug-l: Problems with DWG 2007 Files in ArcGIS 9.1

Do you use DWG files in ArcGIS 9.1?  Then here's information you need to be
aware of. 

AutoDesk 2007 has a new DWG format that won't work in ArcGIS 9.1.  ArcGIS 9.2
will be able to read the new DWG format, but it hasn't been released yet.
Tripp Corbin, an ESRI authorized GIS instructor, said "AutoCAD 2007 does have
a new DWG format that currently can not be read by ArcGIS 9.1 or earlier.
However, AutoCAD 2007 is capable of back-saving to past versions that ArcGIS
9.1 can use.  Also, if CAD users are using Map, Land Desktop or Civil 3D,
they can export to shapefiles, which would allow them to maintain object data
if they are using it."

However, if your computer is running Windows XP, beware of back-saving using
AutoDesk 2007!  Some CAD users at the City of Tallahassee have determined
that if your computer is running Windows XP, back-saving a DWG to an older
version causes problems.  Instead, if you want to use a DWG 2007 file in
ArcGIS 9.1, convert it to an older version using a free AutoDesk utility
called "DWG TrueConvert" (convert to version 2004, 2000, release 14; AutoDesk
2004 to 2006 are similar file formats).  The utility is easy to use and runs
outside of AutoCAD, so GIS users do NOT need AutoCAD installed on their
computers.  You can download the free conversion utility at:
