ATTACHED TOOLS
Female: This represents the tool where the draw bead groove is located. Click the Select button to display the Select Part dialog box illustrated in Figure 10.3.43. After a part is selected, the program will generate a draw bead groove on the attached tool mesh. Click the Remove button to cancel the Attached relationship.

Select Part dialog box
MALE: This represents the tool where the draw bead is located. By default, this is the Lock Tool set when defining the Line Bead.
2.
CENTER LINE
This lists all the draw bead center lines used in geometry Bead 1. The program will select a series of connected draw bead center lines by default.
ADD: Add a draw bead to the list. Click this button to display the Add region illustrated in Figure 10.3.44.

Add draw bead dialog box
SELECT BEAD FROM WINDOW: Select a draw bead in the display area using the mouse cursor. Click this button to display the Select dialog box to prompt the user to select draw beads. Click the left mouse button to select, the middle button to confirm and the right button to cancel. The selected draw beads will be added to the draw bead center line list automatically.
SELECT LINE: Select a draw bead center line which is used to create the draw bead line and add it to the list on the right side. Click this button to display a Select Line dialog box to prompt the user to select a line.
IMPORT: Import a draw bead center line which is used to create the draw bead and add it to the list on the right side. The formats of the imported files are *.cur and *.iges.
The user may select the draw beads to be added from the Add list and click the Finish button to add the selected draw beads to the center line list.
REMOVE: Remove the line beads in the list. This button is enabled after selecting the draw beads in the list.
REVERSE: Reverse the material flowing direction. This button is enabled after selecting draw beads in the list.

SHAPE
Once a draw bead is selected in the above mentioned center line list, the profile shape region of the geometry bead will be displayed in the Geometry Bead page, as illustrated in Figure 10.3.45. The user may select draw beads from one or multiple lists and define their profile shapes. Refer to Section 10.3.1.4 for definition of control parameters.

4.
TRANSITION
Set the transition parameters of geometry bead.
TOLERANCE: The distance tolerance
between two draw beads. If the distance between adjacent end points of two draw
beads is less than this value, it will generate transition geometry between the
two draw beads when generating the geometry bead. Otherwise, it will generate
end points respectively. The default is
LENGTH: The length of the transition
region. The default value is
After finishing the above setup, click the Apply button to generate Bead 1 according to the geometry shape defined by the user.
ADD: Add geometry bead Bead 2, Bead 3, etc.
DELETE: Delete the selected geometry bead.
REMOVE: Only remove the mesh of the selected geometry bead. This operation can only be performed in a reverse order to generation, which means to delete the mesh from Bead 3 to Bead 1. Click this button to display a Warning dialog box illustrated in Figure 10.3.46. Click Yes to remove the draw bead mesh.

EDIT: Edit the section shape of draw bead. This button is enabled after generating the geometry bead. Click this button to display a Warning dialog box illustrated in Figure 10.3.47. Click Yes to re-edit all the section shapes in the current geometry bead

After defining the geometry bead, the program will automatically hide the line bead and negate the effect of line bead. The user does not have to do anything to the line bead.
Note: When switching between different draw beads, the program will adjust the mesh status. If switching to the line bead page, the program will restore mesh to the line bead status; if switching to geometry bead page, the user must update the mesh manually again.
