Once the user clicks on the Copy button, the program will pop up a dialog box as shown in Figure 7.3.36. With this dialog box, the user can Copy, Mirror, Move, or Patch the addendum.

·           COPY

This function enables the user to copy a region of addendum to another position. If there is more than one addendum region in the database, the program prompts the user to select a profile region:

PICK A PROFILE REGION

The user can select a profile in the addendum region to be copied. The entire addendum corresponding to this Profile will be highlighted, as shown in Figure 7.3.37(a). The program will prompt the user to select a target node on part boundary as starting point for the addendum to be copied:

PICK NODE ON DIE BOUNDARY AS DESTINATION POSITION

     

 (a)                                              (b)  

Figure 7.3.37  Copy Addendum

After a destination position is selected on the part boundary, the program pops up an eta/DYNAFORM Question dialog box for the user to confirm the copied position and highlight the new part boundary, as shown in Figure Figure 7.3.37(b). If the position of new boundary is not correct, select No to put the new boundary on the other side of the reference point. Click Yes to accept the boundary location. The selected addendum will be copied as shown in Figure 7.3.38.

·            MIRROR

This function generates the entire addendum by mirroring it about a symmetry plane. The user must define the symmetry axis for the part in the DFE/PREPARATION menu in order to use this function.  Refer to Section 7.1.5 for description about the symmetry definition.

The symmetry axis is displayed after the mirror function is selected. The user selects an addendum segment to display the mirrored boundary. From the displayed eta/DYNAFORM Question dialog box as illustrated in Figure 7.3.39(a), the user selects Yes to mirror the addendum. The mirrored result is illustrated in Figure 7.3.39(b).

Note:   If the generated addendum by the Move, Copy or Mirror function interferes with existing addendum, the operation will be aborted.

·            MOVE

This function enables the user to move a selected addendum segment to another location.  If more than one addendum segment are available in the database, the following message is given in message prompt window:

PICK A PROFILE GROUP

After the user selected a group of profile, eta/DYNAFORM highlights the profiles and addendum of the selected group as illustrated in Figure 7.3.40(a). The following message is then given in the message prompt window.

PICK NODE ON DIE BOUNDARY AS DESTINATION POSITION

Figure 7.3.40  Move Addendum

An eta/DYNAFORM Question dialog box is displayed requesting the user to confirm the selected location. The new boundary on the part is highlighted, as illustrated in Figure 7.3.40(b).  If the location of the new boundary is wrong, the user can select No to put the new boundary on the opposite side of the reference point. Click on the Yes button to accept the boundary location.  The selected addendum will be moved to the location as illustrated in Figure 7.3.41.

·            PATCH

This function is used to fill an addendum segment between two adjacent addenda.  The filled segment is typically a transition area between two adjacent addenda generated using different profile types.  Figure 7.3.42 illustrates a typical addendum region of different profile types.

Figure 7.3.42  Transition Area between Adjacent Regions

The user need to select two end profiles of adjacent addenda after clicking on the Patch button.  After the profiles are selected, the segment is created.  Figure 7.3.43 illustrates a typical transition area generated by the patch function.
