The mitering option is not working for fascias, etc, in 5.1 files that are upgraded to 6.0.

FYI. this has been filed as a bug in 6.0.

the mitering option is in 5.1, and 6.0, but not in 5.1 upgraded to 6.0. I will file a bug. In the meantime, a workaround for upgraded models is to replace the fascia. Newly placed fascia in an upgraded file will offer mitering options.
