Description

0

Curved objects display as a series of vectors controlled by the VIEWRES setting.

1

Circles, arcs, and arc segments in polylines may be displayed as true circles and arcs. Depending on the capabilities of your graphics card, some non-continuous linetypes are also supported. (Recommended)

Note: This setting is automatically changed if you change the hardware settings under GRAPHICSCONFIG. Hardware acceleration will enable this setting for most graphics cards. It is turned off if you select software acceleration but can be manually enabled and in many cases will provide a smoother display image and better performance. During plotting, the setting is also automatically changed depending on the capabilities of the output device.
