There
are some added functions to allow auxiliary surface operation in this interface
for the user to edit the binder. These added functions include Mirror, Copy, Scale,
Split, Trim, Untrim, Respace U-V Line, Extend Edit Section Line, as illustrated in Figure 7.2.73. Refer to Section 5.2, Surface, for detailed description on all these
functions except Extend and Edit Section Line functions.
Figure 7.2.73 Advanced functions
The Extend
and Edit Section Line functions are described below.
·
EXTEND
This
function allows the user to extend the binder surface. The operation of this
function is similar to the one described on Section 5.2.15 Extend Surface.
However, there is a difference from the function
in Section 5.1.15. After completion of the extend operation for binder,
the user clicks on Apply to display an eta/DYNAFORM Question dialog box to
determine if control lines on binder should be deleted, as shown in Figure 7.2.74. Select Yes to delete control lines or select No to
keep control lines.

Question dialog box
Note: When using the Extend function, the extended surface must be the binder of an un-trimmed surface.
·
EDIT SECTION LINE
This
function allows the user to modify binder by editing the section line of the surface.
Once this option is selected, the program will highlight the binder boundary. The
user can select two points on the binder boundary by mouse cursor to create a
section line. Then, drag the section line by mouse cursor to change the shape
of binder.
