Figure 7.3.23 Modify Addendum
The user can modify addendum by
the following 6 methods.
1.
SMOOTH
This option allows the user to
modify addendum by selecting POP Line, Bar Height, Bar Height, Bar Width, CBar
Height or Wall Angle.
Once the Smooth option is
selected, all the section lines and POP Lines on addendum are displayed in
graphic window. As illustrated in Figure 7.3.24, the purple line is the section
line and the black line is the POP Line. Then select a smooth type and select a
Profile. The entire addendum where located the selected profile will be the
object for this smooth operation.

POP Line
This function allows the user to
change the addendum by smoothing the shape of part POP Line. after a profile is
selected, the program will highlight the POP Line in the selected region as
shown in Figure 7.3.24 and pop up a dialog box as shown
in Figure 7.3.25.
Figure 7.3.25 Smooth POP line
There are three methods can be
used to smooth the POP Line.
AUTO SMOOTH
Automatically smooth the POP Line in
the selected region.
MANUAL SMOOTH
Entire POP Line is smoothed according to the movement of slider. The Select Fixed Points option enables the
user to select more than one fixed point. These selected points will not be
moved during the smooth operation.
THROUGH FIXED POINTS
This function allows the user to smooth a segment of the POP Line by
selecting a number of fixed points on the POP Line. Click on the Preview button
to view the smoothed POP Line. If the
smoothed shape is acceptable, clicks on the Apply to accept the smoothed POP Line. Click OK to exit the Smooth dialog box. Click on the Close button in the Smooth
Addendum dialog box to exit the menu.
The profiles and the addendum are automatically updated according to the
smoothed POP Line.

BAR HEIGHT
This function allows the user to smooth
draw bar height of the profiles in the selected region. The program prompts the
user to select a segment of profile to define the region. The operation is similar to the POP Line smoothing.
BAR WIDTH
This function allows the user to smooth
draw bar width of the profiles in the selected region. The program prompts the user to select a
segment of profile to define the region.
The operation is similar to the Bar Height.
CBAR HEIGHT
This function allows the user to smooth
CBar height of the profiles in the selected region. The program prompts the user to select a
segment of profile to define the region.
The operation is similar to the POP Line smoothing.
WALL ANGLE
This function allows the user to smooth
wall angle of the profiles in the selected region. The program prompts the user to select a
segment of profile to define the region.
The operation is similar to the POP Line smoothing.
2.
MORPH
This
function enables the user to modify addendum by morphing the POP LINE, BAR
HEIGHT, BAR WIDTH, CBAR HEIGHT and WALL ANGLE. Once this option is selected,
the user needs to select a morph type and click on the Apply button. The
program prompts the user to select the starting and ending profile to define
the region to be modified.
POP LINE
This function allows the user to
morph selected region of the POP Line.
The user needs to select the starting and ending profile to define the
region that is subjected to morphing. If
more than one region is defined in the addendum, the starting and ending
profiles in each region are highlighted
with a circle at each profile. After
selecting two profiles, the user needs to confirm the selection in order to
highlight the POP Line as illustrated Figure 7.3.29. The morphing operation of POP Line
is similar to the Line Morphing function.
Figure 7.3.30 illustrates the morphed POP Line and
the related profiles. After the POP Line
is morphed, the user can click on the Close
button to dismiss the dialog box. The profiles and addendum are updated
according to the morphed POP Line. Figure 7.3.31 illustrated the updated addendum
after the POP Line is morphed.
Figure 7.3.29 Selected POP Line for Morphing
Figure 7.3.30 Morphed POP Line and Profiles
Figure 7.3.31 Updated Addendum According to the Morphed POP Line
BAR HEIGHT
This function allows the user to
morph draw bar height of the profiles in the user-defined region. The user selects the starting and ending
profile to define the region. The
operation is similar to the POP Line morphing operation, with an exception that
the control line on top of the draw bar is morphed to alter the draw bar height
of the profiles.
BAR WIDTH
This function allows the user to
morph the draw bar width of the profiles in the user-defined region. The user selects the starting and ending
profiles to define the region. This
operation is similar to the BAR HEIGHT line morphing operation with an
exception that the control line on top of the draw bar is morphed to alter the
draw bar width of the profiles.
CBAR HEIGHT
This function allows the user to
morph the counter bar height of the profiles in the user-defined region. The user selects the starting and ending
profiles to define the region. This
operation is similar to the POP Line morphing operation with an exception that
the control line on the bottom of the counter bar is morphed to alter the
counter bar height of the profiles.
WALL ANGLE
This function allows the user to
morph the wall angle of the profiles in the user-defined region. The user selects the starting and ending
profiles to define the region. This operation is similar to the POP Line morphing
operation with an exception that the POP Line is morphed to alter the wall
angle of the profiles.
3.
MERGE
This function enables the user to merge the
control line of the POP LINE, BAR HEIGHT, BAR WIDTH, CBAR HEIGHT and WALL ANGLE
to a selected line. The profiles are
repositioned according to the distance from the control line to the selected
line. Once this option is selected, the Create Spline button will be activated,
as shown in Figure
7.3.22. Clicking on this button, the program will pop up the
Create Spline dialog box as shown in Figure
7.3.33
. Refer to Section 7.1.7.1 Inner Fill for detailed description of this dialog
box.
POP LINE

5.
This
function enables the user to divide an addendum segment into two independent
segments. This function is useful for locally modifying the addendum without
changing the shape of other addenda. Once this option is selected, the options POP LINE, BAR HEIGHT, BAR WIDTH, CBAR HEIGHT and WALL ANGLE will be disabled. The user should select a
profile in the region to be split. If the addendum region where the profile
locates is closed, the program will prompt the user to select another profile
to split this closed region. If the selected region is open, the program will
automatically split this region along the profile.
After
splitting, a new addendum name is listed in the addendum list, while a master
profile type is listed in the master profiles list.
6.
COMBINE
This option allows the user to combine two adjacent
independent regions into one region. Once this option is selected, the
options POP LINE, BAR HEIGHT, BAR WIDTH, CBAR HEIGHT and WALL ANGLE will be disable, the program will prompt the user to
select two adjacent independent addendum regions. After the selection, the
program will automatically combine the two regions into one region.
