Drawing Entity Concepts - Arc
Arcs are drawing entities used to create a background or present information in the job file. As drawing entities, they do not participate in the lighting calculations.
Technical Details
Small straight line segments make up the arc, and their relationship is maintained during modification. That is to say, arcs can be copied, moved, rotated, etc. and the arc will remain intact. To modify an individual segment, explode the arc.
The segment size, or arc resolution is based on the Initial Curve Increment value in the System Settings-Advanced dialog. Arcs are created using the current color and line type on the Properties toolbar.
