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

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
(a) (b)
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.
