Details
"None" option for "Corner Relief" is not available in "Bend" dialog
However it is mentioned in the documentation under Sheetmetal Bend Parameter Preferences.
Solution
This behaviour is working as designed.
"None" option for corner relief of Sheetmetal bend is removed from NX11 as it is not supported.
The concerned Page in documentation refers General Sheetmetal Bend parameter preferences. It is not specific to Bend Command. It is applicable for other sheetmetal commands like "Flange"command
