VI.Define Left and Right Parts

  • ClickDfe PrepatationSymmetry/DoubleAttach.

  • Click Left/Right,Full Inputbutton underDouble Attach(See Figure 16).

  • Click Select button underLeft Part (See Figure 16). Select Lhside in the displayed window (See Figure 17) to define the left part.

  • Click Select button under Right Part and select Rhside in the displayed window to define the right part.

  • If the boundaries of two parts are symmetrical, the system will enter the defined left part name to the textbox under Left Part and enter the defined right part name to the textbox under Right Part (See Figure 18).

  • Display the symmetrical axis between two parts in 3D view (See Figure 19).

  • ClickDFE PreparationTipping.

  • Click the fourth button tip left,sync. right underGeneral/DoubleAttach, which means to tip the right part automatically when tipping the left part (See Figure 20).

  • Enter the rotation center (1600,-700,900) of the left part under Tipping Center.

  • Enter the rotation axis and angle of each time under Manual:

    The first time: rotation axis:U Axis, rotation angle:22°. Click the button (See Figure 20).

    The second time: rotation axis:W Axis, rotation angle:15°. Click the button (See Figure 22).

    The third time: rotation axis:V Axis, rotation angle:9°. Click the button (See Figure 24)

  • Considering the interconnection of two parts and the feeding direction, rotate the left part 90°about U Axis and rotate 90°about W Axis. The final Topview is shown in Figure26 and 27.

  • As shown in the figure, the distance between the left part and right part is too large to generate addendum. Therefore, the distance needs to be narrowed.

  • Rotate V Axis under Manualand enter the moving distance 625 of a single part in the input box for Step. Click button . The final top view is shown in Figure 28 and 29.

  • Click Exitto exit Tippingpage and save the database.

VIII. Create Addendum

between Left and Right Parts

  • Click Boundary FillDouble Fillin theDFE Preparationwindow.

  • ClickAdjust Bdy-Pointbutton and select nodes on the boundary. Adjust the addendum region between the left and right parts (See Figure 31) and click the middle mouse button to confirm.

  • The system automatically generates 7 control lines in the addendum region between the left and right parts and lists them in the Control Lines list box by sequence (See Figure 30)

  • ClickDelete button and select Cntrl ln 5 and Cntrl ln 6to delete these two control lines. Click the middle mouse button to confirm (See Figure 32and 33).

  • Click Add button and select three nodes in the addendum region to add three control lines. Click the middle mouse button to confirm (See Figure 34and 35).

  • ClickApply button to automatically generate addendum and mesh at the juncture of the left and right parts and name it as Double (See Figure 36 ).

  • ClickExit to exitDouble Fillpage.

IX.Inner Fill

  • Click Boundary FillInner Fillin theDFE Preparationwindow.

  • Select Type:Auto Fill(See Figure 37).

  • Enter Hole in the input box for To Part, which means to put the filled hole in Hole layer.

  • ClickApply button and click the middle mouse button confirm the selected inner hole. The system automatically fills the inner hole (See Figure 38).

  • Click Exit to exitInner Fillpage.

X.Create and Modify Binder

  • ClickDFEBindermenu and clickCreate page.

  • Select the first type Flat Binder as binder type. Key in margin: 100and Shift:20. ClickApplyto generate flat binder automatically (See Figure 39).

  • Click Modifyto modify the created binder. Click Add to add section. Do not toggle on By Inputoption. Click Create button (See Figure 40) to create a vertical section line in the middle of part (See Figure 41). The system will name it Ctrl Ln0 automatically.

  • Use the same method to create a horizontal section line. The system will automatically generate a section line at the symmetrical position of the right part and name it as Ctrl Ln1 (See Figure 42).

  • Select Ctrl Ln1and clickEditto edit it. Set 3D view as the front view simultaneously. Change the Z coordinate value for the left and right control points of horizontal section to 15 (See Figure 43). It will be previewed in 3D view after pressing Enter (See Figure 44). If it meets the binder requirements, click Apply to confirm and click Close to exit.

  • ClickApplyto modify binder automatically according to the new section line.

  • Return toCreatepage and click Meshto mesh binder. Enter 30 as the max. and min. mesh size. Click OK to confirm (See Figure 45) and click Exit to exit the Binder window.

  • In the displayed Master window, select the second icon as the Profile Type. Use the default values except changing Plus Part=10 (See Figure 47). Click OK to add the profile named Master 1to Profiles list box (See Figure 48).

  • Click Assign button under Addendum (See Figure 49). ClickApplyin the displayed dialog box (See Figure 50). The system will automatically generate addendum around part (See Figure 51). Click Close to exit. Add the addendum named Addendum1 into the Addendum list box.

  • Since the POP Lineof the part seems to be uneven, the addendum should be modified. Do not exit Addendum Generationwindow.
