AutoCAD would pop up a message, warning of potential stability problems, if a user opened a 2007 version DWG file which did not include this text string.

This file is a Trusted DWG last saved by an Autodesk application or Autodesk licensed application.' This helped Autodesk software users ensure that the files they were opening were created by an Autodesk, or RealDWG application, reducing risk of incompatibilities. In 2006 Autodesk modified AutoCAD 2007, to include 'TrustedDWG technology', a function which would embed a text string within DWG files written by the program: 'Autodesk DWG.

This function was supported by an encrypted checksum and product code (called a 'watermark' by Autodesk), written into DWG files created by the program.

In 1998, Autodesk added file verification to AutoCAD R14.01, through a function called DWGCHECK. (ODA has since rewritten and updated that code.) The most successful is Open Design Alliance, a non-profit consortium created in 1998 by a number of software developers (including competitors to Autodesk), released a read/write/view library called the OpenDWG Toolkit, which was based on the MarComp AUTODIRECT libraries. Several companies have attempted to reverse engineer Autodesk's DWG format, and offer software libraries to read and write Autodesk DWG files. Autodesk sells a read/write library, called RealDWG, under selective licensing terms for use in non-competitive applications. As the biggest and most influential creator of DWG files it is Autodesk who designs, defines, and iterates the DWG format as the native format for their CAD applications. There are several claims to control of the DWG format.

Autodesk estimates that in 1998 there were in excess of two billion DWG files in existence. The DWG format is probably the most widely used format for CAD drawings. From 1982 to 2009, Autodesk created versions of AutoCAD which wrote no fewer than 18 major variants of the DWG file format, none of which is publicly documented. dwg filename extension) was the native file format for the Interact CAD package, developed by Mike Riddle in the late 1970s, and subsequently licensed by Autodesk in 1982 as the basis for AutoCAD.

This protection will prevent unauthorized people to open your drawing file. If you do it right, it will ask you password like below. To try if the password works, close your drawing. You also have the option to encrypt the drawing properties.ДЄfter you click OK, AutoCAD will ask you to enter the password again to confirm. In save as window, click tools on the top right corner, then click security options.ДЄutoCAD will open security options window.

To add password protection, open your drawing. After other users can open the drawing, they can work with it just like any other drawing. Note: Autodesk has removed this capability since AutoCAD versions 2016.Д¬an we protect our AutoCAD drawing with password? Yes, this is a protection provided by AutoCAD, to prevent other people from opening your drawing.
