SURFACE (CTRL+S)
The functions in this menu allow the user to create and modify surfaces in eta/DYNAFORM. The dialog box is illustrated in Figure 5.2.1.
eta/DYNAFORM uses two sets of dotted lines to show the contour of a surface. These lines are called U-V lines.
• U-V LINE
This function controls the on/off display of the U-V line on the surface.
• SURFACE NORMAL
This function controls the on/off display of the normal direction of the surface while the U-V line function is on.
A detailed description of these options is given in the following sections.
