ASSIGN
eta/DYNAFORM provides two methods to create the addendum. If the BY SEGMENTS option is toggled ON, the user is can create the addendum by multiple segments with different master profiles. If the BY SEGMENTS option is toggled OFF, the entire addendum will be created based on a master profile.
After the user selects a Master profile and clicks the ASSIGN button as in Figure 6.3.12, DYNAFORM opens a dialog window (Figure 6.3.13).
Figure 6.3.13 Insert Addendum
Select one of the options, Outer, Inner or Corner addendum, and click the APPLY button.
OUTER ADDENDUM (toggle on Outer)
If BY SEGMENTS is toggled ON, the SELECT REGION button is activated. Click SELECT REGION, and the program highlights the outer boundary of the part and prompts with the following message.
SELECT A NODE ON PART BOUNDARY AS STARTING POINT
After selecting a node on the part boundary, the program will prompt the user to select the end point of the region.
SELECT A NODE ON PART BOUNDARY AS END POINT
After two nodes are selected on the outer boundary, click APPLY to create a partial addendum in the defined region. Figure 6.3.14 illustrates a typical partial addendum.
If BY SEGMENT is toggled off, clicking the APPLY button will create the addendum around the entire outer boundary. Figure 6.3.15 illustrates a typical complete addendum of a part.
Figure 6.3.14 Create Addendum by Segment
Figure 6.3.15 Create the entire Addendum by a master profile
INNER ADDENDUM (toggle on Inner)
The SELECT REGION button will be activated when the INNER option is toggled ON.
If BY SEGMENTS is toggled ON, click the SELECT REGION button to select two nodes on the same inner boundary. Click APPLY to generate the partial addendum in the selected region.
If BY SEGMENTS is toggled OFF, click the SELECT REGION button to select a node on an inner boundary.
CORNER ADDENDUM (toggle on Corner)
This function is used to connect a part with flange and the addendum. In this case, the flange may be part of the binder. Refer to Figure 6.3.17 for a typical part with flange on the binder.
Follow these steps to create a corner addendum.
When the CORNER option is selected, the dialog window in Figure
6.3.13 will change to Figure 6.3.16.
Click the SELECT PROFILE button to select a profile on the
addendum boundary. The selected profile will be highlighted as shown in
Figure 6.3.18.
Select two nodes on the part boundary as shown in Figure 6.3.19. The
program will prompt the user to conform if the defined corner is correct.
Click YES to accept the defined corner region.
The APPLY button in Figure 6.3.15 is activated. Click APPLY to generate the corner addendum as shown in Figure 6.3.20.
