Much like Adobe
®
PDF files, DWF files are no more alterable than printed
paper copies. Unlike PDF files, however, DWF files retain detailed design
information and scale, and are therefore more suitable for architects, engineers,
and designers.
The newest version of the DWF file format, DWFx, is based on the XML Paper
Specification (XPS) from Microsoft. DWFx makes it easier to share design data
with reviewers who cannot install software.
DWFx files can be opened and printed instantly using the free Microsoft XPS
Viewer, which comes pre-installed on computers using the Microsoft Windows
Vista
®
operating system. (For the Windows XP operating system, the Microsoft
XPS Viewer can be downloaded directly from Microsoft.) Unlike DWF files,
DWFx files include additional information to display design data in the
Microsoft XPS Viewer. As such, DWFx files are larger than corresponding DWF
files.
TIP In Design Review, you can choose between DWFx and DWF as the default file
format on the General tab in the Options dialog box.
Currently, the Microsoft XPS Viewer does not support sheets containing 3D
content, password-protected content, object properties, restricted content, or
georeferenced map coordinates. In the Microsoft XPS Viewer, when attempting
to view sheets DWFx files containing any of these unsupported features, a
warning directs you to download and view the DWFx file in Design Review.
NOTE All references to DWF in this documentation implicitly include DWFx, unless
specified.
A Digital Design Workflow
Most DWF files begin as a drawing or model created in such Autodesk programs
as AutoCAD, Inventor, and Revit. Before a DWF file is published, the person
publishing the DWF file determines which features (model, layouts, layers,
blocks, named views, and so on) are included in the published DWF file. Once
the content has been determined, the designer publishes the file from its
original format to a DWF file and sends the DWF file to the review team to
begin the digital design review process.
Receive. Reviewers get the DWF file from the publisher and open it in
Design Review to verify the content (a 2D drawing, 3D model, or image).
