Pan and Zoom with Raster and OLE
Controls the display of raster images and OLE objects when you use Realtime
PAN and ZOOM. Clear this option to optimize performance. If dragging
display is turned on and you select Pan and Zoom with Raster and OLE, a
copy of the object moves with the cursor as you reposition the original.
Dragging display controls whether an outline of the object is displayed
while you drag it. The DRAGMODE system variable controls dragging
display. (RTDISPLAY system variable)
Rendered Object Smoothness
Controls the smoothness of shaded and rendered curved solids. The value
you enter for Rendered Object Smoothness is multiplied by the value you
enter for Arc and Circle Smoothness to determine how to display solid
objects. To improve performance, set Rendered Object Smoothness to 1 or
less when drawing. A higher number decreases display performance and
increases rendering time. The valid range is 0.01 to 10. The default setting
is 0.5. This setting is saved in the drawing. (FACETRES system variable)
Segments in a Polyline Curve
Sets the number of line segments to be generated for each polyline curve.
The higher the number, the greater the performance impact. Set this option
to a low value such as 4 to optimize performance for drawing. Values range
from -32767 to 32767. The default setting is 8. This setting is saved in the
drawing. (SPLINESEGS system variable)
Show Page Setup Manager for New Layouts
Displays the Page Setup Manager the first time you click a layout tab. Use
this dialog box to set options related to paper and plot settings.
Show Shortcut Keys in Tooltips
Displays shortcut keys when you move the cursor over buttons on the
toolbar.
Show Silhouettes in Wireframe
Controls whether silhouette curves of 3D solid objects are displayed as
wireframes. This option also controls whether mesh is drawn or suppressed
when a 3D solid object is hidden. This setting is saved in the drawing. Clear
this option to optimize performance. (DISPSILH system variable)
Show Text Boundary Frame Only
Displays the frames for text objects instead of displaying the text objects.
After you select or clear this option, you must use REGEN to update the
