Inventor Interop

Inventor Addins must reference the Inventer Interop library (Autodesk.Inventor.Interop.dll) in order to access Inventor's API. This template includes a copy of the Inventor 2023 Interop in the lib folder. If needed, you can change the reference to a different version. The Autodesk.Inventor.Interop.dll can be found in the following location:

C:\Program Files\Autodesk\Inventor 20xx\Bin\Public Assemblies

xx should be set to the version of Inventor you want to reference.
