Improvements have been made to the way graphics are displayed in GstarCAD 2022.
One of those improvements is the new ANTIALIAS system variable, which enables users to control whether anti-aliasing is applied to 2D objects in 2D wireframe visual styles.
How to turn off/on the ANTIALIAS
The initial value of ANTIALIAS variable is 1, which mean the anti-aliasing is on.
To turn off the anti-aliasing, just set the value to 0.
