Now you can create a non-revolved section view using a cutting plane line that contains curved elements, such as arcs or fillets.
To use this capability, clear the Revolved Section View option 
on the Section View command bar before you click to place the view.
Previously, you could only create a revolved section view with a cutting plane line that contains arcs.
Note:
Arcs in cutting planes must be connected to a line at both ends. You cannot begin or end a cutting plane with an arc. For more information, see the help topic, Section views.
