Hi Norm,
Hope you are doing good.
Regarding the query, this is to inform that SuperPro being our legacy product there are no such enhancements available in the same.
The latest SDK that we have is 7.1 which provide support till AutoCAD 2010.
As such SuperPro is not tested (and supported) at our end with latest AutoCAD version, you can go ahead and test the same in your test environment.
Also, please be informed that the latest product which we have is LDK and we recommend to use the same for future.
For cost related queries you need to get in touch with Sales.
Thanks,
Heena
