About the Attached Flat Wall User Interface
The Flat user interface consists of commands, tabs, and shortcut menus. To access the Flat tab, click Sheetmetal > Flat.
Use the following configuration options to control the default values and behavior of selected tool settings:
smt_drive_tools_by_parameters—Uses parameter values as the default values of selected tool settings and to automatically update features when parameter values change.
smt_drive_bend_by_parameters—Uses parameter values to control the default value of bend angle and bend dimension location settings and to automatically update features when parameter values change.
* 
If you want to enable smt_drive_bend_by_parameters, you must also set smt_drive_tools_by_parameters to yes.
In the following descriptions, [<Parameter Value>] indicates that tool settings are controlled by parameters.
