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 in 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. To manual select bends, click Manual and select the bends to edit.
3. To automatically select bends, click Automatic .
4. To change the fixed geometry reference, click References and click the Fixed geometry collector. Select a different reference in the model.
Editing Bend Attributes
1. To remove a bend, select it and click Remove Bend.
2. To remove a bend relief, select it and click Remove Bend Relief.
3. To change the bend allowance equally on both sides of the bend, click Anchor bend apex.
4. To change the bend radius, select an option from the Radius list. Set the dimension scheme:
◦ —Sets the bend dimension from the inside surface.
◦ —Sets the bend dimension from the outside surface.
◦ —Sets the bend dimension according to the location set by the SMT_DFLT_RADIUS_SIDE parameter.
5. To change the bend angle, select an angle from the Angle list, or type a new angle value. Change the direction and set the bend angle deflection.
◦ To change the direction of the bend angle click .
◦ —Dimensions the bend angle by measuring the deflection from straight.
◦ —Dimensions the bend angle by measuring the resulting internal angle.
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 .
