Open DWF/DWFx Files in Google Chrome

From a browser perspective, for the longest time you were only able to view DWF/DWFx files in Microsoft Internet Explorer.  Last year, we provided version 1.0 of the Firefox Add-on for Autodesk Design Review to enable this functionality in Mozilla Firefox.

Time marches on. The latest update to the Firefox add-on, version 1.1, and a minor Windows registry modification can enable Google Chrome to view DWF/DWFx files too.

First things first.

  • With recent versions of Firefox, Chrome, and Design Review (2009, 2010, or 2011) on your computer, download and install the Firefox Add-on for Autodesk Design Review version 1.1. (If you previously installed version 1.0 of the add-on, version 1.1 will update it automatically.)

Now for the registry tweak.

  1. Open the Windows Registry Editor (regedit.exe).
  2. Navigate to HKEY_CLASSES_ROOT\.dwf.
  3. In the Registry Editor's right pane, double-click Content Type. The Edit String dialog box opens and Model/vnd.dwf is shown in the Value Data text box.
  4. Change the capital letter “M” in Model/vnd.dwf to a lowercase “m” so it looks like this model/vnd.dwf
  5. Click OK to update the value.
  6. Exit the Registry Editor.

You can now open DWF/DWFx files in Chrome either by dragging and dropping them into the browser or by opening HTML files with embedded DWF/DWFx files.

Problems caused by improperly editing the Windows registry could render your computer operating system unusable. Microsoft has provided a wealth of critical information you need to know about the registry in the Microsoft Knowledge Base at
Use the Microsoft® Registry Editor only at your own risk and only after backing up the registry as well as the system.dat and user.dat files as outlined in ARTICLE-ID: Q132332 "How to Back Up the Registry" in the Microsoft Knowledge Base. Additional information about the registry is also contained in the Help topics in the Microsoft Registry Editor.
