What is a CAS file?

A CAS file is a license file used by Autodesk products such as AutoCAD and Revit. It contains information that validates a purchased software copy. CAS files are used in a "cascading" license setup, where a network installation of the software can be used by multiple networked computers.

More Information

CAS files use the filename CascadeInfo.cas. These files can potentially become corrupt if the computer unexpectedly crashes, denying access to the software. If this occurs, consult Autodesk support to resolve the issue.

By default, the CascadeInfo.cas file is located in the following directory:

  • Windows Vista/7: C:\​ProgramData\​Autodesk\​ADLM\​
  • Windows XP: C:\​Documents and Settings\​All Users\​Application Data\​Autodesk\​ADLM\​
  • macOS: /​Library/​Application Support/​Autodesk/​Adlm/​.config/​

A CAS file may also be a 3D model used by some games in the Total War strategy game series. It may contain a model of a building, unit, or other game object. CAS files are saved with .TGA and .DDS images used for texturing the models.

CAS files can be imported and exported with Autodesk 3ds Max modeling software using the Vercengetorix CAS Importer/Exporter script.
