Location of Library Files (AutoCAD Mechanical Toolset)

The AMLIBRARY command uses library files to store blocks and drawing files for reuse.

The path to the folder containing library files is in the system editor key Acad/MPathsLibPath (Configuration setting gen@Paths@LibPath).

By default, the key points to C:\ProgramData\Autodesk\AutoCAD Mechanical 2027\Acadm\Gen\Lib.
