AutoCAD and Its Applications—Advanced
In the default 3D environment based on the
acad3D.dwt
template, the default display
mode, or visual style, is Realistic. In this visual style, all objects appear as solids and
are displayed in their assigned layer colors. Other display options are available. These
options are discussed in detail in Chapter 15, but are given here as an introduction.
• 2D Wireframe. Displays all lines of the model using assigned linetypes and
lineweights. The 2D UCS icon and 2D grid are displayed, if turned on. If the
HIDE
command is used to display a hidden-line view, use the
REGEN
command
to redisplay the wireframe view.
• Wireframe. Displays all lines of the model. The 3D grid and the 3D UCS icon
are displayed, if turned on.
• Hidden. Displays all visible lines of the model from the current viewpoint and
hides all lines not visible. Objects are not shaded or colored.
• Sketchy. Edges appear hand-sketched.
• Shades of Gray. Gray shades are shown with highlighted edges.
• Conceptual. The object is smoothed and shaded with transitional colors to
help highlight details.
• Realistic. The model is shaded and smoothed using assigned layer colors and
materials.
• Shaded. A smooth-shaded model is displayed, but edges are not shown.
• Shaded with Edges. Edges are displayed on the smooth-shaded model.
• X-Ray. The model appears transparent.
A variety of options can be used to change individual components of each of these
visual styles. A complete discussion of visual styles is given in Chapter 15. Detailed
discussions on rendering, materials, lights, and animations appear in Chapters 15
through 20.
NOTE OT OT TE
When the visual style is
2D
Wireframe, you can quickly view the model
with hidden lines removed by typing HIDE. The
HIDE
command can
be used at any time to remove hidden lines from a wireframe display.
If
HIDE
is used when any other visual style is current, the
Hidden
visual style is set current.
