This function enables user to transform the addendum and binder from
original part design to another part that shares similar shape. The dialog box
of Create New Addendum is illustrated in Figure
7.8.6.

SELECT NEW PARTS
This function
enables user to select the new part. The new part will replace the original
part as DIE.
SHOW NEW
This
option is utilized to show/hide the new die.
SHOW OLD
This
option is utilized to show/hide the original die.
POSITION NEW PARTS
The
positioning between the new and original parts is very important to ensure good
result. Due to similarity between the new and original parts, the user can use
three different methods to position the new part:
l 3 Point Absolute
Three
reference points are selected on the new die parts and original die parts. The
first selected reference point on new die is used to position the new die parts.
The other two reference points are used to orient the new die part. Three
arrows are plotted on screen after the reference points are selected. An
illustration is shown in Figure
7.8.7.
Note: The distance between the selected three points should large enough to ensure good positioning result.
Figure 7.8.7 Three Points Absolute
l 3 Point Plane
The
average of the three selected points (the center point of three points) is used
new die parts. The center point of selected point on new die parts is moved to
the center point of selected three points on old die part accurately after
positioning. The other two points are used to orient the new die part. Three
arrows are plotted on screen after the points are selected.
l LCSàLCS
This method is used to position the
new die parts through defining LCS on new and original die parts. The LCS on
new die parts is matched with the LCS on original die parts to position the new
and original die parts.
l Tip with Die part
This method is to used to position
the new die parts through assigning the tipping result of original die parts to
the new die parts.
UNDO
Undo the
last position operation.
APPLY
This function
enables user update the addendum of new die parts. An illustration of updated
addendum is shown in Figure
7.8.8.
Due to
minor differences between the new and original die part, some gaps or overlap
elements may exist between the original addendum and the new die part. The user
may need to adjust some points on original addendum to the new die parts. After
the function is selected, some arrows are displayed from point on original
addendum to the new die part. The user has to adjust the corresponding point by
selecting the head of an arrow. Then, the user can select a new position on screen
to change the corresponding point. Figure
7.8.8 illustrates the position of corresponding points.
Figure 7.8.8 Moving the corresponding points
After the
adjustment is completed, the user can click on middle mouse button to update
the addendum on new die parts.
