COM Changes

If you are using the COM API, you need to update the object version to 13.4 (from 13.3 used in Autodesk Civil 3D 2021). The objects and interfaces exposed have remained the same, but you should reference the new libraries, which are installed by default to: C:\Program Files\Common Files\Autodesk Shared\Civil Engineering 134.
