The

displays the current part and contains the following commonly used functions.
Figure 1.4.1 Display Options
CURRENT PART
This function enables the user to
set the current part. It is very important to set the current part in the
eta/DYNAFORM because most of the results generated from the different functions
will be stored into the current part by default. The user can click on button to change the current part. After clicking
the button, the system will pop up a Current Part dialog box, as illustrated in
Figure
1.4.2. The user can choose one of the parts as the current part. The
current part name will be displayed in the text box to the right of the Current
Part button.

This function enables the user to display the
normal direction of each element with an arrow at the center of the element and
perpendicular to the surface of the element. For a solid element, the arrow
points toward the bottom surface of the element. See Figure 1.4.4.

NODE (toggle)
Toggle on/off checkbox to show/hide nodes.
HIDDEN (toggle)
This function improves the display integrity
of 3D model. The user may toggle on/off the
hidden lines function checkbox while the Shade option is toggled on. This effect creates opaque elements that
prevent objects in the background from showing through objects in the
foreground.
FILL COLOR (toggle)
The Fill Color function fills displayed
elements with a designated color. The function
is unable to accurately represent the depth perspective of a model. The displayed part may appear to warp or
penetrate other parts. However, the Fill Color command displays an accurate 3D
model display of the parts when it is used in conjunction with the HIDE PLOT
option.
SHADE (toggle)
Display the 3D parts as if they were
illuminated by a light source. Parts that are not directly exposed to the light
source are appropriately shaded to imitate actual shading.
