- Formula
- Defines the variable of the radius of the circle or the side length of the square.
- Circle
- Defines a circle as the opening tool. Specify the radius of the circle (A). It must be greater than the calculated minimum radius so the rebending is possible. If you set the radius to 0, you can prevent the tool from being used, in which case the corner will not be opened at all (B).
Figure 1: Tool for a circular opening Note: The program calculates the minimum value of the radius for the circle, and suggest it as a radius value of the opening tool. You can increase the value. If you reduce the value, the rebend is prevented.- Square
- Defines a square as the opening tool. Define the length of the square’s side. It must be greater than the calculated minimum length so the bending back is possible. If you set the side length to 0, you can prevent the tool from being used, in which case the corner will not be opened at all.
