18 Free DWG viewers – Browser based and Offline

You can view your AutoCAD files without using AutoCAD or other paid software using these free AutoCAD viewers.

These free CAD file viewers also support several other CAD file formats.

In this article, I have listed the free online browser-based as well as offline DWG viewers.

The DWG viewers are categorised based on how you can access them like from a browser or an offline installer and I have also taken into consideration other properties like markups, inspection tools and file conversion or plotting functions.

So, with that let’s start with our first DWG file viewer.

Autodesk viewer

Autodesk is simply the market leader in CAD and engineering software and it’s obvious that they will have a free drawing file viewer.

So, the free CAD file viewer from Autodesk is aptly called Autodesk viewer.

You can add comments to your files and even share these files using simple links with collaborators and stakeholders.

You only need an Autodesk account for this which you can create for free in no time.

As the software is from Bentley it prefers the eDrawings and will show it as the default file format, but you can change that and select from all the other available file formats that it supports.

Despite being small and lightweight software, it is packed with great 2D drafting tools and it can handle all kinds of DWG and DXF files which it supports.

There are no 3D tools in this software and so it is only going to work properly for 2D drawings.

FreeCAD

FreeCAD is a full-fledged CAD software and it’s not just a DWG or other CAD file viewer.

And then there are some that are in a different category like fee cad software but still, they get the job done.
