About the Bend User Interface
The Bend user interface consists of commands, tabs, and shortcut menus. Click Model > 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.
Commands
• Bend Placement buttons:
◦ —Bends the material up to the bend line.
◦ —Bends the material on the other side of the bend line.
◦ —Bends the material on both sides of the bend line.
• —Flips the area that remains fixed.
* 
When you use the Flip button the original bend ID is applied to the new fixed side.
• Bend Type buttons:
◦ —Bends the material using a value to define the bend angle.
◦ —Bends the material to the end of the surface.
• Bend Angle list—Lists predefined and user-defined values. [<Parameter Value>] , an additional option, sets the angle according to the BOARD_BEND_ANGLE parameter.
• Bend Dimension Scheme buttons:
◦ —Dimensions the bend angle by measuring the resulting internal angle.
◦ —Dimensions the bend angle by measuring the deflection from straight.
• Bend Radius list—Lists predefined and user-defined values, and By Parameter for the bend radius:
◦ Thickness—Uses a radius equal to the thickness of the segment.
◦ 2.0 * Thickness—Uses a radius equal to twice the thickness of the segment.
◦ [<Parameter Value>]—Uses a radius set by the BOARD_BEND_RADIUS parameter.
• Dimension Location buttons:
◦ —Dimensions the bend from the outside surface.
◦ —Dimensions the bend from the inside surface.
◦ —Dimensions the bend according to the location set by the BOARD_RADIUS_SIDE parameter.
Tabs
• 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.
Shortcut Menus
Right-click the graphics window to access the shortcut commands:
• Bend Surface or Bend Line—Activates the Bend surface or bend line collector.
• Bend Line End 1 Placement—Activates the reference collector for the first end of the bend line.
• Bend Line End 2 Placement—Activates the reference collector for the second end of the bend line.
• Bend Line End 1 Offset—Activates the offset reference collector of the first end of the bend line.
• Bend Line End 2 Offset—Activates the offset reference collector of the second end of the bend line.
• Clear—Removes the reference from the active collector.
• Define/Edit Internal Bend Line—Opens Sketcher to sketch a bend line.
• Flip Fixed Area—Flips the area that remains fixed.
