From the developer:
CADVault allows AutoCAD® users to secure both graphical and non-graphical elements within an AutoCAD drawing file by embedding those elements into an electronic vault object. The vault object is a self contained graphical entity that can place restrictions on how the embedded elements may be used or exposed depending on the credentials of the person using the drawing file.
