Using the Modify binder interface, as illustrated in Figure 7.2.38, the user can easily modify the binder by adding control lines to change the binder to a desired shape.

·           CONTROL LINES

This function is used to list the added control lines, as shown in Figure 7.2.38. In the list, point the cursor to any control line in the list and double click the left mouse button, the program will automatically display the corresponding serial number for all control lines for the user to identify. Therefore, the user can select the serial number to perform edit and delete operations.

·           ADD

This function allows the user to add control lines on the binder. Once this button is selected, two methods for adding control lines appear on the interface, as shown in Figure 7.2.39. When using the first method, the user can directly use the cursor to select a point on the binder and then drag the mouse cursor to generate a control line. The cursor should be on the binder when selecting point. After the control line is added, the Edit and Remove buttons are activated, as shown in Figure 7.2.40. Another method is to select By Input which activates the DX and DY fields, and the Vector button. DX indicates the X coordinate for distance from the stamping center. DY indicates the Y coordinate for distance from the stamping center. The user can input DX value, DY value or DX, DY value to accurately control the location of control line. Then, select Vector to define the vector direction of the control line. In the end, select Create to generate a control line with user defined location, as shown in Figure 7.2.41.

Note:   When adding the control lines, it is suggested to use the top view. The location of control lines generally provide the best results when defined at the boundary of part so that the user can modify the binder conveniently. In addition, Apply can only be activated when there are intersecting control lines.

·           EDIT

This function allows the user to modify control lines. Select a control line in the Control Lines list and click on this button to display a 2D window, as shown in Figure 7.2.42. In the 2D window, the control lines and part section lines for their locations are displayed. The user can change the binder by editing control lines so that the binder shape is more suitable for the part. After editing a control line, the user can directly select another control line in 3D window by cursor for editing in the 2D window without exiting the 2D window.

Figure 7.2.42  2D Curve window

The functions for 2D window are described below:

In the 2D window, add control points on control lines by simultaneously pressing the <Shift> key and clicking the left mouse button, as shown in Figure 7.2.43. Move the locations displayed in the 2D window for control lines and section lines by simultaneously pressing the <CTRL> key and clicking the middle mouse button, as shown in Figure 7.2.44. Scale the control lines and section lines by simultaneously pressing the <CTRL> key and clicking the right mouse button, as shown in Figure 7.2.45 and Figure 7.2.46.

The user can change the shape of control lines via moving the control point by cursor, as shown in Figure 7.2.47. When moving the control point, the control lines on screen will highlight the moved control points, as shown in Figure 7.2.48.

GRID

Display the grid in the 2D window. If this option is toggled off, the grid will not be displayed.

WHITE

Set the background color of 2D window. If this option is toggled off, the background color turns from white to black.

SWAP

Click on Swap button to change the direction of Die part section line.

REDO

Redo the latest operation. If there is nothing to redo, this button is disabled.

UNDO

Cancel the latest operation. If there is nothing to cancel, this button is disabled.

X, Y, Z

Display the coordinates of the selected control points. The user can enter the Z coordinate value manually and press <ENTER> to confirm.

dZ

Display the relative distance between the location after moving and the initial location of the selected control point along Z direction upon the global coordinate system.

LEN

Display the length of the selected line segment.

R

This function is activated when two sides of the selected control points are straight lines. The user can enter the radius value manually and press <ENTER> to confirm. The program will generate an arc, as shown in Figure 7.2.49.

Figure 7.2.49  Generate Arc

DIST TO PART

Display the distance between control point and part. The user can enter the distance value manually and press <ENTER> to confirm. The selected control point will move to the entered distance location.

SLOPE

Define angle between straight/curve segment of control line and horizontal.

STRAIGHT

This option is activated after a line segment is selected. If the selected line segment is curve, the user can select this option to change it to a straight line.

CURVED

This option is activated after a line segment is selected. If the selected line segment is straight, the user can select this option to change it to a curve.

VIEW DIST

Measure the view distance. Select this option to measure the distance between two points in the 2D window by mouse cursor, for example, the distance between control line and part section line at the location for control line, as shown in Figure 7.2.50. The distance value will be shown in the displayed dialog box as illustrated in Figure 7.2.51. The user can also use this function to measure the distance between two points in the 3D window.

REF LINE

Display the selected line as the reference line for control line shape. The user can generate part boundary lines by Create Boundary Line function described in Section 5.1.5. Then select the part boundary line as the reference line for control line shape, as shown in Figure 7.2.52.
