About the Bend User Interface
The Bend user interface consists of commands, tabs, and shortcut menus. Click > 
Bend to access the Bend tool.
Bend to access the Bend tool.Use the following configuration options to control the default values and behavior of selected tool settings:
• board_drive_tools_by_parameters—Uses parameter values as the default values of selected tool settings and to automatically update features when parameter values change.
• board_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 board_drive_bend_by_parameters, you must also set board_drive_tools_by_parameters to yes. |
In the following descriptions, [<Parameter Value>] indicates that tool settings are controlled by parameters.

• Placement
Use this tab to select bend line references.
◦ Bend surface or bend line—Displays a surface, edge, or curve reference.
When an edge or curve is selected, these options are available:
▪ Details—Opens the Chain dialog box that displays detailed information about the selected edge chain.
▪ Offset bend line—Offsets an edge or curve reference by a specified value.
• Bend Line
Use this tab to sketch or locate the ends of a bend line, when a surface reference is selected.
◦ Sketched bend line—Click Sketch to open Sketcher to sketch a bend line.
◦ Bend line end 1—Sets the references for the first end of the bend line.
▪ Reference——Displays the surface, edge, or vertex reference in the collector.
▪ Offset reference—Displays the surface or edge offset reference in the collector. Specify a value in the box.
◦ Bend line end 2—Sets the references for the second end of the bend line.
▪ Reference—Displays the surface, edge, or vertex reference in the collector.
▪ Offset reference—Displays the surface or edge offset reference in the collector. Specify a value in the box.
• Transitions
Use this tab to sketch transition areas.
◦ Lists any sets of transition areas. Click Add Transition to define a new transition area.
◦ Sketch—Opens Sketcher to sketch a transition area.
◦ Remove—Removes a transition area.
◦ Flip—Flips the location of the transition area to other side of bend line.
• Relief
Use this tab to define relief.
◦ Define each side separately— Sets the relief for each side of the bend separately.
▪ Side 1—Sets the relief for the first end of the bend.
▪ Side 2—Sets the relief for the second end of the bend.
◦ Type—Lists the types of relief:
▪ No Relief—Adds no relief.
▪ Slit
—Adds a slit relief.
▪ Stretch—Adds a stretch relief.
▪ Rectangular—Adds a rectangular-shaped relief.
▪ Obround—Adds an obround-shaped relief.
▪ [<Parameter Value>]—Adds a relief set by the BOARD_BEND_REL_TYPE parameter.
• Bend Allowance
Use this tab to set a feature-specific bend allowance to calculate the developed length of the bend. When you click A feature specific set up, these options become available:
◦ By K factor—Calculates the developed length according to the K factor. To change the value for K factor, type a new factor value or select a value from the list.
◦ By Y factor—Calculates the developed length according to the Y factor. To change the value for Y factor, type a new factor value or select a value from the list.
◦ By bend table—Calculates the developed length using a bend table. To choose a different bend table, select one from the list.
• Properties
Use this tab to display detailed feature information.
◦ Name—Shows a feature name.
◦ 
—Shows feature information in a browser.
