To Change the Developed Length
By default, the calculation of the developed length is based on the Y factor and K factor values defined in the Part Bend Table or the Feature Bend Table. Modifying the developed length affects both the unbent geometry and bend back features.
1. Select the feature on the Model Tree for which you want to modify the developed length. Right-click and choose Edit from the shortcut menu. The dimensions are displayed in the graphics window.
2. Double-click the developed length value and type a new one, or select Return to Driven to drive the dimensions by the bend table or Y-factor and specify the new developed length.
3. Middle-click to exit Edit mode.
4. Regenerate the model. The new value overrides the default developed length.
* 
If you change the radius, the developed length changes accordingly unless you explicitly override the developed length.
If you change the developed length, the bend radius is not affected and loses its relativity with the developed length.
If you have changed the developed length in Edit mode and then changed the bend radius, the developed length does not change after regenerating the model.
