How to Open DWG Files on Mac (Free DWG Viewers for macOS)

If you received a .dwg file on your Mac, you’ve probably discovered that macOS doesn’t support them natively. 

• ❌ macOS does not support DWG files natively in Quick Look or Preview
• ❌ Autodesk’s free DWG TrueView is Windows-only
• ❌ AutoCAD for Mac requires an expensive subscription and is overkill for just viewing
• ❌ Many DWG viewers are online-only which cause privacy concerns or law related aspects
• ❌ Many DWG viewers can’t export / print properly
• ❌ Free DWG tools are either lagging (slow) or the UI is not intuitive
• ❌ Some tools only support older version DWG files, for newer one it will just generates a blank page

In this guide, we’ll show you the best free DWG viewers for Mac that are more lightweight to open, view, and modify DWG files with smooth performance. 

 

Quick Answer: How to Open a DWG File on Mac

• Use an online DWG viewer - Fastest, no install: Upload the file to Autodesk Viewer (web) to view DWG in Safari/Chrome (only support viewing)
• If you need editing: Use AutoCAD Web - free for viewing, offer professional editing with 30 days free trial
• Best free desktop option: Install QCAD or LibreCAD (good for basic 2D DWG/DXF workflows, open DXF more reliably than DWG)
• If your goal is just checking a few dimensions or pass the design to a collaborator rather than CAD editing, eDrawings Viewer or Enolsoft DWG viewer from Mac App Store is the lightweight and straitforward option

 

The DWG TrueView for Mac Myth

Note that AutoCAD's DWG TrueView for Mac is not available, Autodesk does **not** offer a desktop version of *DWG TrueView* for Mac, if you see infomation that promising DWG TrueView for Mac, it is likely a Windows-only file or unsafe. The best free official alternative is Autodesk Web Viewer.

The only way to use DWG TrueView on Mac is to use virtualization software such as Parallels Desktop or VMware Fusion to run Windows and DWG TrueView on your Mac. But we don't recommend it when the following DWG viewers are available.

QCAD Community edition - Open-source software that has almost all the options of Autodesk Viewer

QCAD Community edition is an open-source application that makes opening DWG files very easy. In our test it has better DWG support than LibreCAD and it also has almost all the tools you need to edit a DWG file. For small DWG files it loads very quickly, but for files larger than 30MB it takes a long to open. 

QCAD also comes with a profession version. The professional version of QCAD adds a few additional resources and tools which are not open source.

LibreCAD is a free, open source 2D CAD software for Windows, Mac and Linux. Most of the interface and handle concepts are analogous to AutoCAD, so it is very easily to get started for users with experience of CAD.

LibreCAD uses the AutoCAD’s .dxf file format internally to import and save files. When opening an existing AutoCAD file with LibreCAD you should have the correct file format selected in order to have access to the file, by default it can only open DXF files with DWG options are grayed out, you need to switch the opening format to DWG in the open dialog box. and for exporting it allows export to many other file formats like png, jpeg, and pdf.

• Free and open-source.
• Works on macOS, Windows, and Linux.
• Light-weight 2D CAD software.
• Supports isometric 3D drawings making.
• Layers properties settings like color, line type, visibility etc. 
• Dimensioning and annotation tool supporting.
• Support switching between the metric and imperial units.
• Provides editing tools like trim, extend, mirror, scale, and rotate etc. 
• Export drawings to PDF, SVG, and DXF. 
• Available in more than 30 languages.

Cons:

• Limited DWG Support (For newer version DWG you may need to convert it to DXF first).
• Doesn’t support complex 3D DWG.
• Takes time to get used to the toolbar.
