Extract or open the French Language Pack installation files.
Supported base products and compatibility
Back in 2009/2010, language packs were exclusively available to Autodesk Subscription customers. If you had an active subscription for AutoCAD 2010, you could download the French language pack directly from the Autodesk Subscription Center. Access was region-locked according to "language families" to streamline support, a system that often sparked user confusion.
: You must have the core AutoCAD 2010 product already installed and activated before adding the language pack.
One of the greatest advantages of using an Autodesk language pack is that the core command structure remains accessible. If you are accustomed to English commands but are using the French interface, you can still use the English commands by prefixing them with an underscore ( _ ). For example: Typing draws a line using native French commands.
