How to convert DWF to DWG? (Solved)

Introduction

If you need to edit or further develop a design sent as a DWF (Design Web Format) file, converting it to DWG (AutoCAD drawing) is often required. This guide explains clear, beginner-friendly methods to convert DWF to DWG, lists step‑by‑step instructions, offers alternative approaches, gives troubleshooting fixes for common errors, and shares practical tips to get accurate results. Each method includes pros, cons, and security considerations so you can pick the best workflow for your needs.

What is DWF (Design Web Format)?

DWF is a lightweight, read-only format created by Autodesk for sharing and reviewing designs without full CAD software. DWF files are much smaller than DWG because they typically store images and simple geometry rather than full editable objects, layers, or block definitions. That makes DWF ideal for review and markup, but it also means some original CAD data (layers, attributes, object properties) may be missing when you try to convert back to DWG.

Why convert DWF to DWG?

  • To edit the drawing in AutoCAD or other CAD software.
  • To reuse geometry, create new details, or generate construction documents.
  • To collaborate with CAD users who require native DWG files.

Keep in mind: because DWF is often a “view-only” export, not all elements can be fully recovered. Expect to re-create or reassign some layers, texts, or block attributes after conversion.

Method 1 — Convert DWF to DWG using AutoCAD (best when you have AutoCAD)

Steps:

  1. Open AutoCAD and start a new drawing or open the DWG you want to add the DWF content to.
  2. Use the command DWFATTACH to attach the DWF file as an underlay (this places the DWF as a reference in your drawing).
  3. If possible, use DWFIMPORT (available in some AutoCAD versions) — if not available, attach and then:
    • Trace the visible geometry with line, polyline, spline, etc., or
    • Attempt to explode the underlay (note: exploding may be limited or unavailable depending on AutoCAD version and DWF content).
  4. Clean and organize: place traced objects on proper layers, assign lineweights, and fix text/fonts.
  5. Save the finished drawing as a DWG.

Pros:

  • Full control over resulting geometry and layering.
  • No need to upload sensitive files to third-party servers.

Cons:

  • Manual tracing can be time-consuming.
  • Some elements (block attributes, object data) may be lost and need reconstruction.

Method 2 — Use Autodesk Design Review + AutoCAD (good for 2D drawings)

Steps:

  1. Install and open Autodesk Design Review (free).
  2. Open the DWF file and inspect it.
  3. Export or print the DWF to PDF (Design Review lets you produce a high-quality PDF).
  4. Open AutoCAD and use PDFIMPORT to import the PDF as geometry (AutoCAD converts vector PDF content into polylines, text, etc.).
  5. Clean up imported geometry, reassign layers/text styles, then save as DWG.

Pros:

  • Useful for detailed 2D vector drawings.
  • Often preserves scalable vector data better than raster-based exports.

Cons:

  • Extra steps and possible loss of object metadata.
  • Fonts and text may need re-mapping.

Method 3 — Use online converters (fast and convenient, but watch privacy)

Steps:

  1. Choose a reputable online converter (examples: Zamzar, CloudConvert, AnyConv).
  2. Upload your DWF file.
  3. Select DWG (or DXF) as the output format.
  4. Download the converted file and open in AutoCAD to verify/clean up.

Pros:

  • Quick; no local software installation required.
  • Handy for occasional conversions.

Cons / Warnings:

  • Do not upload confidential or regulated files to online services unless you trust their privacy policies.
  • Conversion quality varies—complex or 3D content may not convert well.
  • There is potential for file size limits or paywalls.

Method 4 — Use third‑party desktop software (best for batch or complex files)

Popular tools: AutoDWG DWF to DWG Converter, ReaConverter Pro, and other commercial converters.

Steps:

  1. Install the chosen converter.
  2. Add one or multiple DWF files (batch mode if supported).
  3. Choose DWG (or DXF) output and set options (version, layer mapping, output folder).
  4. Run the conversion and open the results in AutoCAD for verification.

Pros:

  • Often faster and more accurate for many files.
  • Batch processing and conversion options (output DWG version, layer handling).

Cons:

  • Usually paid software.
  • Still may require manual cleanup after conversion.

Alternative workflows

  • Convert DWF to DXF first (if supported) and then open DXF in AutoCAD—DXF is a CAD exchange format that may preserve more geometry in some pipelines.
  • If DWF is actually DWFx (XPS-based), print to PDF using Windows print-to-PDF, then use PDFIMPORT.
  • If you have access to the original DWG source, always request the native DWG from the sender to avoid conversion loss.

Common errors and how to fix them

Missing layers or object properties

  • Cause: DWF often lacks layer/metadata.
  • Fix: Recreate layers manually in AutoCAD and use MATCHPROP (Match Properties) to reassign properties. Consider grouping and naming conventions to speed re-creation.

Text replaced by gibberish or missing fonts

  • Cause: Font substitution or SHX text not preserved.
  • Fix: Install required fonts or replace text by using Find and Replace. For SHX-to-text issues, consider retyping critical annotations or use a text recognition workflow.

Imported geometry is broken into many small segments

  • Cause: Vector conversion creates fragmented polylines.
  • Fix: Use PEDIT (Polyline Edit) with the Join option or run OVERKILL to clean duplicate and overlapping entities.

Underlay cannot be exploded

  • Cause: DWF underlays are sometimes non-explodable or protected.
  • Fix: Trace over the underlay manually or use PDF export + PDFIMPORT route to get editable vectors.

Scale or units are incorrect

  • Cause: Conversion changes units or export scale.
  • Fix: Check drawing units (UNITS command) and use a known dimension in the drawing to scale imported geometry: use the SCALE command referencing a measured segment.

Missing raster images or hatches

  • Cause: Embedded bitmaps may not carry through converters.
  • Fix: Extract images from the original DWF (Design Review may allow image extraction) and reinsert them into the DWG. Recreate hatch patterns manually if needed.

Tips for best results when converting DWF to DWG

  • Always keep a backup of the original DWF file before starting conversion.
  • Ask the sender for the original DWG when possible—this is the simplest way to avoid data loss.
  • For critical projects, use a trusted desktop converter and test on a small sample file first.
  • Check and set correct drawing units and scale immediately after importing.
  • Use layer naming conventions and create a layer template to speed cleanup.
  • For batch jobs, test one file first and review conversion settings before processing many files.
  • If privacy is a concern, avoid online services—use local tools or AutoCAD workflows.

FAQ

Can I convert DWF to DWG without AutoCAD?

Yes. You can use online converters or third‑party desktop tools (AutoDWG, ReaConverter). However, results may vary and desktop tools often give better control than online services.

Will converting a DWF to DWG restore all original data?

No. DWF files typically lack layers, block attributes, and object metadata, so some information cannot be fully restored. Expect to recreate layers, attributes, and some text manually.

Are online DWF to DWG converters safe for confidential drawings?

Only if the service clearly states strong privacy and security (encryption, file deletion policy). For sensitive or regulated data, prefer local conversions (AutoCAD or desktop software).

Can 3D DWF convert into a 3D DWG properly?

3D conversions are inconsistent. Some converters handle 3D entities, but complex models, surfaces, and metadata often don’t translate perfectly. Verify the result carefully and be prepared for manual reconstruction.

What is DWFx and how does it affect conversion?

DWFx is the XPS-based variant of DWF. It behaves like a DWF but may require different handling—printing to PDF or using Design Review that supports DWFx usually produces better results than generic converters.

Should I convert to DXF instead of DWG?

Sometimes converting to DXF is better for interoperability because DXF is a widely supported exchange format. You can then open the DXF in AutoCAD and save as DWG if needed.

How do I handle fonts and SHX text issues after conversion?

Install missing fonts or replace text in AutoCAD. For SHX issues, you may need to recreate text or use manual mapping. Keep a list of required fonts and request them from the sender when possible.

Is there a way to automate bulk conversions?

Yes—use third‑party tools that support batch processing (AutoDWG, ReaConverter, or scripts if the tool has CLI support). Always test on a sample file and verify conversion settings before running large batches.
