Both apps allow users to view, edit, share and create 2D CAD drawings. AutoCAD web app is accessed entirely online in a web browser on any computer. AutoCAD mobile app is included with AutoCAD and AutoCAD LT and provides similar features on iPhone and Android devices.
What is DWG?
DWG refers to both a technology environment and .dwg files, the native file format for Autodesk’s AutoCAD® software. Autodesk created .dwg in 1982 with the very first launch of AutoCAD software. DWG files contain all the information that a user enters in a CAD drawing. This data can include designs, geometric data, maps and photos. The .dwg file format is one of the most commonly used design data formats, found in nearly every design environment.
What is DWG TrueView used for?
DWG TrueView allows you to open, view and plot AutoCAD, DWG and DXF files. Use it for printing, creating PDFs and converting between AutoCAD formats.
What if I only need file-viewing access?
For stakeholders who only need file-viewing access, we offer free viewers without a subscription. If you're transitioning to named user, make sure that you take advantage of the trade-in offers available to you.

DWG technology environment
The DWG technology environment contains the ability to mould, render, draw, annotate and measure. While commonly associated with AutoCAD, DWG technology is an integral part of many of our CAD products.
TrustedDWG™ technology lets you know of potential incompatibility when a file was not last saved by an Autodesk software and identifies files that might not be supported by Autodesk software.
