Convert DWF to DWFX

A recipient or document system may require Autodesk’s XPS-based .dwfx format instead of .dwf. Converting the published package preserves distributable CAD content, but it does not recreate the original editable DWG, RVT, or Inventor source file.

What the DWF format is

DWF (Design Web Format) is Autodesk’s publishing format for distributing 2D drawings, sheets, 3D models, measurements, and review information without sharing native CAD files. AutoCAD, Civil 3D, Revit, Inventor, and other Autodesk products can publish DWF files for design reviews, construction-document exchanges, consultant submissions, and drawing archives.

Autodesk Design Review can open DWF files for viewing, markup, measurement, and printing. DWF content is published data, not an editable native CAD model; its geometry, layers, parameters, constraints, and source-application objects cannot generally be edited as they were in the original project.

What the DWFX format is

DWFX (usually written .dwfx) is Autodesk’s DWF variant packaged with Microsoft’s XPS technology. It can be opened by Autodesk Design Review and, for supported page content, by XPS-compatible Windows viewers. DWFX is intended for exchanging published CAD documents rather than for editing the source design.

XPS compatibility does not guarantee support for Autodesk-specific features. 3D navigation, specialized markups, measurements, multiple-sheet behavior, and other review data are handled more reliably in Autodesk Design Review or another application that explicitly supports DWFX.

Convert DWF to DWFX with Design Review

1. Install and open the Windows version of Autodesk Design Review. Autodesk has not actively developed the product for years, so obtain the installer from an Autodesk source or an organization-approved software repository and verify that it runs on the target Windows version.
2. Choose File → Open and select the source .dwf file.
3. Choose File → Save As, select DWFx (*.dwfx) in the file-type list, specify the destination, and save.
4. Reopen the new .dwfx file and check every sheet, page orientation, view, markup, measurement, and 3D area required by the recipient.

Design Review is the most suitable desktop conversion option because it reads the published DWF package and writes DWFX without reducing the content to raster images or PDF pages. If DWFx is absent from Save As, that Design Review build cannot perform the conversion; use the original CAD application instead.

Publish from the original CAD application

When the original project is available, republishing is preferable to converting an already published file. In AutoCAD, use the release-specific Output → Export → DWFx command or select a DWFx plotter in the publish or plot settings. Revit, Inventor, and related Autodesk products provide DWFx export or publishing options that vary by release.

Republishing lets you choose current sheets, views, layers, page setups, and 3D publishing settings. It can also produce different content from the existing DWF, so compare the result with the required source views before distribution.

Online conversion and compatibility limits

There is no consistently dependable mainstream online service for a direct, feature-preserving DWF-to-DWFX conversion. Services that advertise DWF conversion commonly produce PDF, SVG, PNG, or another output instead of DWFX. Autodesk Viewer is useful for inspecting supported files online, but it is a viewing service, not a dependable converter.

Do not upload confidential drawings to an online service unless it explicitly lists DWFX as the output, states how uploaded files are handled, and is approved for the project. For sensitive or feature-rich CAD packages, use Design Review or republish from the source Autodesk application.

The conversion retains published vector and review content better than PDF or image export, but it cannot recover information omitted when the DWF was created. DWFX is not guaranteed to be smaller than DWF because its XPS-based package can add overhead. Test the converted file in the recipient’s actual viewer, especially when it contains 3D content, markups, measurements, or multiple sheets.
