Autodesk Volo View Express is a free DWG viewer; required for Advanced DWG Print
Editor: View Express is a software program created specifically for viewing files that are created with some Autodesk products. It is a separate program and does not affect the operation of the main program you are installing. With Volo View Express, you can view DWG, DXF, DWF, RML, IPT, IAM, and IDW files, along with raster images that have been inserted into DWG files.

With several Autodesk products you have the ability to Create Drawing Web Format (DWF) files, but not to view these files. The DWF file format was originally developed so users could produce small files that can be quickly accessed over the Internet and viewed in a Web Browser. A DWF file will contain a subset of the drawing information contained in the original drawing file.

You can use Volo View Download Express to view and print DWF files, and add markup annotation to the file, without making any changes to the original drawing.

You may want to install Volo View Express if :
you plan to create DWF files to send to customers who want to view drawing information before being sent the full drawing files.
you want to mark up a drawing file.
you need a Viewer program to view any of the file types listed above
Volo View Express requires 24MB of hard disk space when it is installed, but will need more disk space temporarily during the installation process. you can free download Autodesk Volo View Express 3.0 Build 996 now.
