protecting (and unprotecting) your files with password: Autocad and more

Normally, in the project and documentation sector of a company, for transfer, sending or protecting drawings and designs, it is necessary to find a feature to prevent unwanted opening of files.

The most versatile means of protecting files of any nature is the use of passwords. You already know how to enter a password in your Autocad files?

To protect your DWG files through password is very simple (up to AutoCAD 2015):

• With your file open go to "File" > "Save As".
• In the new window, click "Tools"> "Security Options", as shown below:

• Enter your password and password confirmation. Soon! Your file is protected!
