Enabling and disabling the Thick Line and Solid Line buttons affects the wireframe as follows:
When Thick Line is enabled, the wireframe has a thickness of 2 pixels.
When Thick Line is disabled, the wireframe has a thickness of 1 pixel.
When Solid Line is enabled, the wireframe is unbroken.
When Solid Line is disabled, the wireframe is dashed.
Increasing Editing Speed
To speed up editing, disable the Graphic Regen button in the Setup menu. Instead of waiting for the graphics
objects to be regenerated at the end of an editing operation, the objects appear at the display resolution.
This can be a useful time-saving feature.
Hiding the Object Vertices
Each object is defined by two or more vertices. These vertices, or tangent handles, appear while you are
drawing or editing the object.
Disable the Control Points button in the Setup menu to turn off the display of the vertices while you are
drawing or editing the object. This feature is useful if you want to trace the outline of a figure.
Displaying Anamorphic Geometry
Select Use Aspect Ratio in the Rendering area of the Setup menu to draw and display anamorphic geometry.
For normal display, click Use Aspect Ratio and switch to Use Square Pixels.

Anti-Aliasing for Objects
The jagged edges that can occur along diagonal and curved lines in geometry are caused by aliasing, or
insufficient spatial sampling of the image. The process of minimizing jagged edges by increasing the sampling
rate is called anti-aliasing.
Use the Anti-alias field in the Rendering Setup menu to specify an anti-aliasing factor for geometry. When
the value is set to 1, no anti-aliasing occurs. Best results are obtained with a value of 4.
