DWF Files
You can use AutoCAD to create Design Web format (DWF) files. A DWF file
is a 2D vector file that you can use to publish your AutoCAD drawing on the
World Wide Web or an intranet network. DWF files can be opened, viewed,
and plotted by anyone using Volo
®
View 3 or Autodesk
®
Express Viewer™ .
With Volo
View 3 or Autodesk Express Viewer, you can also view DWF files
in Microsoft Internet Explorer 5.01 or later. DWF files support real-time
panning and zooming as well as control over the display of layers and named
views.

Use Drawings from Different Versions and
Applications
You can share drawing files from AutoCAD and AutoCAD, drawing files from
previous versions, and drawing files that contain custom objects. In some
cases there are limitations.
Save Drawings to Previous Drawing File Formats
You can save a drawing created with AutoCAD LT 2004 in a format compat-
ible with previous versions of AutoCAD. This process creates a drawing with
information specific to AutoCAD LT 2004 stripped out or converted to
another object type. As the drawing is exported, a log lists changed or lost
information.
If you use the current release of AutoCAD to open a drawing created with a
previous release, and you do not add any information specific to the current
release, you can then save the drawing in the format of the previous release
without loss of data.
Note To use files with AutoCAD Release 12 or AutoCAD Release 2, save the
drawing using the AutoCAD R12/LT2 DXF option.
If you need to keep a drawing created in a previous release in its original for-
mat, either mark the file as read-only, or open it in AutoCAD LT 2004 and use
the File Type options in the Save As dialog box to save it in its original format.
