Problem Description:
Create Non-Tangential Project (Check on Non-Tangential Alignment) and go to Analysis > Create Profiles , you will see the "Working Drawings" button is grayed out and hence fails to generate profiles.
Note: Please refer the below link in which attached the dataset for testing.

Workaround:
In the Add-Ins pull down there is a PreXM Long Sections tool which takes you to the old Long section viewer. This has a working drawings option which appears to be OK when using a Non-tangential alignment.
