How to Open a DWG file
A DWG -- an abbreviation for "drawing" -- file contains vector image data for two-dimensional or three-dimensional computer-aided design drawings. DWG files are created by CAD programs such as AutoCAD, IntelliCAD or DraftSight. At the time of publication, a copy of AutoCAD 2016 costs $4,195 -- but you don't have to purchase any licenses to open DWG files. Autodesk provides two free utilities that open and view the drawings: DWG TrueView and AutoCAD 360 (online).
