Editing Bends
Use the Edit Bend tool to edit existing bends or introduce new bends by selecting relevant geometry in your model. All selected bends are edited to have the same attribute values.
* 
You cannot edit a bend that is the flat state.
Follow the steps below to edit bends.
2. Edit attributes for the selected bends.
3. Set options for bend geometry.
6. Click .
Selecting Bends
1. In an open sheet metal part with bends, click Flexible Modeling > Edit Bend. The Edit Bend tab opens.
2. For manual selection , select the bends to edit., then right-click,
3. To automatically select bends, click .
4. To change the fixed geometry reference, right click and select Fixed Geometry or click References and click the Fixed geometry collector. Select a different reference in the model.
Editing Bend Attributes
1. To edit bend attributes, use the commands on the tab and shortcut menu:

Description
Remove Bend
Removes selected bends.
Remove Bend Relief
Removes bend reliefs when bends are removed.
Anchor bend apex
Applies bend allowance equally on both adjacent sides of the bend.
box
Bend angle drag handle in graphics window
Changes the bend angle.
Flip Bending Direction
Flips the bend direction.
Dimensions the bend angle by measuring the resulting internal angle
Dimensions the bend angle by measuring the deflection from straight.
box
Sets the bend radius value.
Sets the bend dimension from the outside surface.
Sets the bend dimension from the inside surface.
Sets the bend dimension according to the location set by the SMT_DFLT_RADIUS_SIDE parameter.
Setting Bend Options
You can use the graphics window shortcut menu or the Options tab edit options for selected bends.
1. To apply the bend allowance change equally to both sides of the bend apex, click to select the Anchor bend apex check box.
2. To change the geometry that remains constant during the bend operation, select an option from the Bend editing option list. In the Options tab, an illustration for each option shows the geometry that remains constant.
◦ Constant flange length (default)—Keeps the length of the flanges or walls constant.
◦ Constant wall height—Keeps the height of the flanges or walls constant.
* 
The inner side of the wall is kept to the constant height.
◦ Constant leg length—Keeps the length of the legs on both sides of the bend constant.
◦ Constant flat length—Keeps the length of the flat piece constant.
Setting Adjacent Conditions
1. To set treatment for bend reliefs, corner reliefs, and corner seams, use one of the following options:
◦ Click Adjacent Conditions, the tab opens.
◦ Right click in the graphics window and click Edit Adjacent Conditions, right-click again to open the Edit Adjacent Conditions shortcut menu.
The default is to recreate the same type of relief or seam that exists for the bend being edited.
2. Use the adjacent conditions to do the following:
a. Remove the bend reliefs or change them to Rip reliefs.
b. Remove corners reliefs or change them to V Notch reliefs.
c. Remove corner seams or change them to Open corner seams.
3. To continue geometry from side surfaces, click to select the Extend neighboring side surfaces check box.
4. To recreate round or chamfer geometry adjacent to recreated corner seams, click the Create round/chamfer geometry check box. Rounds or chamfers are recreated in the new location.
Changing Bend Allowance Settings
To edit the bend allowance, use the Bend Allowance tab.
1. To retain the current developed length, leave the default Use current settings.
2. To use the developed length calculation set for the part, click Use part settings.
3. To define feature specific bend allowance settings, click Use feature settings. Select one of the following options.
◦ 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.
Changing Properties
To change feature properties, use the Properties tab.
1. To edit the feature name, type a new one in the Name box.
2. To display information on the feature in the browser, click .
