Free DWG Viewing with DWG TrueView
DWG™ at Autodesk refers to two different, but related things. First, it is a powerful technology environment that Autodesk places in many of its popular software products. DWG technology contains the ability to mold, render, draw, annotate and measure, among others. Second, .dwg is the native file format for AutoCAD data files that contain all of the pieces of information a user enters, from designs and geometric data to maps, photos and beyond.
Autodesk created DWG in 1982 with the launch of its first version of AutoCAD. And while it is still commonly associated with our flagship product, it is an integral part of many of our other products, including our AutoCAD-based products, AutoCAD Design Suite, Autodesk Revit and Autodesk Inventor. With .dwg files circulating throughout virtually every design industry, DWG technology has made the .dwg file format one of the most commonly used design data formats.
Developed by Autodesk, and comprising the core file format for AutoCAD® software and AutoCAD-based products, TrustedDWG™ technology is the original, efficient, and accurate way for storing design data created using AutoCAD and AutoCAD-based products. The TrustedDWG functionality in Autodesk software identifies .dwg files that were not last saved by an Autodesk or RealDWG® software licensee product. Users can opt to receive notification when the .dwg file they are opening was saved using an application that was not created by an Autodesk product or RealDWG® software licensee. This alert system identifies files that Autodesk may not be able to support and lets users know that Autodesk cannot guarantee the integrity or compatibility of that .dwg file with AutoCAD or any other Autodesk application.
