Different edge types
can be displayed using different colors and linetypes. You can also
add special effects, such as Jitter and Line Extensions.
In
a shaded or wireframe model, the visual style sets the visibility
and appearance of isolines, facet edges, silhouette edges, occluded
edges, and intersection edges. Facet edges (the edges between planar
faces representing a surface) are displayed only when the angle
between the facets is smaller than the crease angle value you specify.
Edge modifiers such as Line Extension and
Jitter, produce the appearance of a model that is still in the conceptual
phase. Jitter makes lines appear as though they were sketched with
a pencil. Line Extension produces another kind of hand-drawn effect.
NotePlot styles are not
available for objects with the Jitter edge modifier applied.
Control the display of
occluded lines in 2D View
Occluded
lines are hidden lines made visible by changing its linetype and color.
In 2D View, you can change the display of occluded linetype with OBSCUREDLTYPE system variable
and occluded color with OBSCUREDCOLOR system variable.
To control the display
of occluded lines in 2D View, you can:
- Hide them or make them partially visible
with dashes and dots.
- Make them completely visible.
- Make them distinctive or indistinctive
by changing its color.
NoteYou can only change
occluded color when the occluded lines are partially or completely
visible.
ImportantAfter you have changed
the settings for occluded lines, use the
HIDE command to regenerate
the drawing and display the changes.
To control the display
of edges and edge colors
- Click View tab
Visual Styles panel 
Visual Styles Manager. 
- With the current visual style selected
in the sample images, in Edge Settings, Show, select Facet edges,
Isolines, or None.
- If Isolines is selected, specify the
number of lines.
- In Color, specify a color. Select Color
opens the Select Color
dialog box.
To add a line extension
effect to edges
To add a jitter effect
to edges
- Click View tab Visual Styles panel Visual Styles Manager.
- With the current visual style selected
in the sample images, in Edge Modifiers, adjust the amount of jitter
in Jitter.
To control display of silhouette
edges
- Click View tab Visual Styles panel Visual Styles Manager.
- With the current visual style selected
in the sample images, in Silhouette Edges, Show, select Yes or No.
- If Yes is selected, specify a width for
silhouette edges.
To control the display
of occluded edges
- Click View tab Visual Styles panel Visual Styles Manager.
- With the current visual style selected
to Hidden in sample images, in Edge Settings, Show, click Facet
Edges.
- In Occluded Edges, Show, select Yes.
- In Color drop-down, select a color from
the list.
- In Linetype drop-down, select a linetype.
To control the display
of occluded lines and color
- Click View tab Visual Styles panel Visual Styles Manager.
- With the current visual style selected
to 2D Wireframe in sample images, in 2D Hide - Occluded Lines, Linetype
drop-down, select a linetype.
- In Color drop-down, select a color from
the list.
- On the command line, enter HIDE and then press
Enter for changed occluded line and color settings to take effect.
