How to convert DWF to DWG? (Solved)

If you’ve ever wondered how to convert DWF (Design Web Format) to DWG (AutoCAD Drawing), you’re not alone. Whether you’re looking to edit your design in AutoCAD or share it with others, converting between these formats is a common need. While DWF files are typically used for viewing and sharing designs, DWG files are essential for editing and further development. In this article, we’ll walk you through various methods for converting DWF to DWG.

What is DWF (Design Web Format)?

Before diving into the conversion process, it’s important to understand what DWF (Design Web Format) actually is. This file format was developed by Autodesk to enable users to share designs without the need for complex CAD software. DWF files are much smaller than DWG files because they contain only “low-intelligence entities” such as 2D images or 3D models, rather than editable layers and blocks. For example, when a designer sends a DWF file, the recipient can view the drawing without being able to alter it. This makes DWF an ideal format for distributing drawings to clients or colleagues for review and markups.

However, there are instances where you may want to convert a DWF file back to the DWG format, especially if you need to edit the drawing. But converting DWF to DWG is not always straightforward, and it’s important to understand that not all elements can be fully recovered during the conversion.

Why Convert DWF to DWG?

Imagine you receive a DWF file from a colleague for review. It’s helpful for marking up changes, but you soon realize you need to make adjustments directly in AutoCAD. Since DWF files are intended primarily for viewing and not editing, this means you must convert the DWF back into a DWG file, which allows full access to the original design elements.

However, it’s important to remember that DWF files are stripped of certain data during their creation—such as object properties and layers—which cannot be fully restored when converting back to DWG.

Method 1: Converting DWF to DWG Using AutoCAD

For those who have AutoCAD installed, converting DWF to DWG is a relatively simple process, though not without limitations. Follow these steps:

  1. Open AutoCAD and start a new drawing.
  2. Use the DWFATTACH command to attach the DWF file to your drawing as an underlay.
  3. Once the DWF is attached, you can trace or copy the geometry from the DWF underlay.
  4. Use the Explode command to break the underlay into its individual components, which can then be edited.
  5. Finally, save the file as a DWG.

This method is useful but limited. The DWF underlay is essentially a reference file, and not all drawing elements will be perfectly replicated. You might find that certain elements, such as layers or block attributes, are missing.

Method 2: Using Autodesk Design Review

Another method involves using Autodesk Design Review, a free tool designed for viewing and marking up DWF files. Here’s how you can convert DWF to DWG using this software:

  1. Install Autodesk Design Review (it’s free).
  2. Open the DWF file in Design Review.
  3. Use the Measure or Print functions to export the drawing to a PDF.
  4. Open AutoCAD and use the PDFIMPORT command to import the PDF as AutoCAD geometry.
  5. Save the imported PDF as a DWG file.

This method is a bit more complex than directly using AutoCAD, but it gives you the advantage of handling 2D drawings and 3D models more effectively.

Method 3: Using Online Converters

For those who don’t have AutoCAD installed or prefer a more accessible approach, several online tools can convert DWF to DWG. Some popular online converters include:

  • Zamzar
  • AnyConv
  • OnlineConvert

Simply follow these steps:

  1. Upload the DWF file to the converter’s website.
  2. Choose DWG as the output format.
  3. Click Convert and download the converted file.

While this method is convenient, be cautious about using online tools for sensitive files. Additionally, online converters may struggle with complex files, and the quality of the converted DWG might not always match your expectations.

Method 4: Using Third-Party Software

Several third-party programs also offer DWF to DWG conversion. One such tool is Autodwg DWF to DWG Converter Pro, which provides a more specialized and reliable solution for users who need to convert large numbers of files or more intricate designs.

To convert DWF files using Autodwg:

  1. Install Autodwg DWF to DWG Converter Pro.
  2. Open the software and select Add File(s) to choose your DWF file.
  3. Select DWG as the output format and specify the output folder.
  4. Click Convert to start the process, then retrieve your DWG file from the designated folder.

While Autodwg offers a robust solution, it is a paid software, so it might not be the best option for those looking for free methods.

Bulk Conversions and Advanced Needs

If you need to convert multiple DWF files at once, software like ReaConverter Pro offers bulk conversion capabilities. Simply add your files, choose DWG as the target format, and let the software handle the rest. ReaConverter is more affordable than some competitors, and it supports over 650 file formats, making it a flexible option for a wide range of conversion needs.

Conclusion

In summary, there are several ways to convert DWF to DWG, each with its own advantages and drawbacks. If you have AutoCAD, using the DWFATTACH command is a simple option. For those without AutoCAD, using online converters or tools like Autodesk Design Review can also get the job done. And for professionals handling multiple files or complex designs, third-party software offers powerful conversion tools. Ultimately, the method you choose will depend on the complexity of your design and your access to the necessary software.
