The System Editor is an advanced tool for viewing and changing the configuration variables stored in the Windows registry.
The System Editor helps AutoCAD Mechanical toolset administrators manipulate the behavior of the system under exceptional circumstances. We do not recommend changing any variable values in this dialog box unless it is necessary.
The System Editor does not validate any changes. This behavior can result in your making changes that break your system. We recommend that you note the original value of any configuration variable before changing it. You can alternatively make a backup of the Windows Registry before changing anything.
