Class: Sketchup::ArcCurve
Overview
An ArcCurve is a Curve that makes up part of a circle. This is the underlying class for circles as well.
You can think of ArcCurves as entities that were created with SketchUp's Arc or Circle drawing tools and Curves as entities that were created with the Freehand drawing tool.
However, keep in mind that all Curves in SketchUp are really edges with some extra data attached to them. When you use the API to draw a Curve or ArcCurve, you are really drawing edges.
ArcCurve is a subclass of Curve, so all of the methods that are available to Curves are also available to ArcCurves.
Instance Method Summary collapse

#center ⇒ Geom::Point3d
Get center of the circular arc.

#end_angle ⇒ Numeric
Get the angle of the end of the arc measured from the X axis in radians.

#normal ⇒ Geom::Vector3d
Get arc normal, the vector that is perpendicular to the plane of the arc.

#plane ⇒ Array<Numeric>
Get arc plane.

#radius ⇒ Numeric
Get arc radius.

#start_angle ⇒ Numeric
Get the angle of the start of the arc, measured from the X axis in radians.

#xaxis ⇒ Geom::Vector3d
Get the X axis of the arc's coordinate system.

#yaxis ⇒ Geom::Vector3d
Get the Y axis of the arc's coordinate system.
