Once Orient is selected, a dialog box as
illustrated in Figure 7.3.54 appears. With this dialog box, the user can change
the orientation of a profile relatively to the POP Line by using four methods.

·
BY
This function allows the user to select a
profile to change its orientation relatively to the POP Line. If the function
is selected, the following message is printed in the message prompt window:
SELECT
PROFILE TO CHANGE ORIENTATION
After a profile is selected, the user needs to
pick a location on the POP Line. The selected profile is moved to a plane
defined by the original part boundary node and the new POP Line location. After completing the profile orientation operation
by clicking the middle mouse button, the user clicks on Close button to exit
the function if Auto Update Addendum is selected. The addendum mesh is
automatically updated.
·
BY RANGE
This function allows the user to change the orientation
of a selected profile relatively to the POP Line by selecting a profile
segment. The user can select this option and click the Apply button to
highlight some profiles in order to display the profile region. The user can
also customize the profile region. Double click on the left mouse button to
cancel the specified highlighted profiles and click on the left mouse button to
select and highlight the specified profile. Then, select a profile in the
selected region and drag the profile left and right. All the profiles in this
region will move accordingly. Therefore, the orientation of this profile
segment relatively to the POP Line will be changed. After completing the
profile orientation operation by clicking the middle mouse button, the user
clicks on Close button to exit the function if Auto Update Addendum is
selected. The addendum mesh is automatically updated.
·
BY REF PROFILE
This function allows the user to select a
reference profile and then select other profiles. The direction of the
reference profile will be an orientation standard for the selected profile.
After completing the profile orientation operation by clicking the middle mouse
button, the user clicks on Close button to exit the function if Auto Update
Addendum is selected. The addendum mesh is automatically updated.
·
BY SYMMETRY AXIS
This function allows the user to adjust the
orientation of profile so that it can parallel to the orientation of the
symmetry plane. For symmetric parts, after the completion of half addendum, the
user usually mirrors the generated addendum onto the other half. Therefore,
before the mirror operation, the user needs to adjust the profile orientation
into the symmetry plane.
Once this dialog box is selected, the program
will prompt the user to select a profile to adjust its orientation. After a
profile is selected, if it locates within the symmetry plane, this profile will
be adjusted into the symmetry plane automatically. Figure 7.3.55 shows a typical result of symmetry operation.

Profile Adjustment (b) After Profile Adjustment

If the selected profile
is not in the symmetry plane, a dialog box as illustrated in Figure 7.3.56 appears.

Click Yes to continue operation. Click No to
cancel this operation.
After the completion of operation, the program
prompts the user to select other profiles to continue adjustment, or click on
the right mouse button to exit this function.
Note: This function is only available for the symmetric parts and cannot be applied on non-symmetrical parts.
