To Create an Interop Assembly of the Transmittal Type Library (ActiveX/ATO)

An interop assembly needs to be generated from the of the CAD Standards type library (TLB) file before you can link the library to a project. You create an interop from a TLB file with the Tlbimp.exe application.

Note: Based on the edition and version of Microsoft Visual Studio installed, you might need to download and install the Windows SDK to access the Tlbimp.exe application. The Windows SDK can be downloaded from https://developer.microsoft.com/en-us/windows/downloads.
