Detailed Description

Interface class for an Overlay Arc Model.

An overlay model is positioned in 3D space and drawn onto a model set specific overlay.

An arc has the following geometric parameters:

Start Angle: Change which part of the ellipse is used to draw the arc
End Angle: Change which part of the ellipse is used to draw the arc
Position: Change the position of the arc's origin
Dimensions: Change the dimensions of the ellipse used to draw the arc
Max Angle Segment: Affects the number of vertices used by changing the angular difference between vertices along the arc. If you want to use X vertices to draw the arc, then set Max Angle Segment equal to PI / X

An arc has the following style parameters:

Line Width: Change the width of all of the arc's line segments
Line Color: Change the color of all of the arc's line segments
Line Stipple Pattern: Change the stipple pattern of all of the arc's line segments

Special Considerations:

In a 2D plane, the positive Y-Axis is 0 radians with clockwise being the positive direction
If the start and end angle are 0 and 2 * PI respectively, an ellipse is drawn
If the height of the arc is 0, a line is drawn
