CircularArcClass

A portion of a circle that connects two points optionally has measure, height and ID attributes at each endpoint.

Description

A CircularArc is an object that describes a portion of a circle or a complete circle. In geometric terms, a CircularArc is a special case of an EllipticArc, where the major and minor axes are equal. Consequently, every point on the arc is equidistant from the CenterPoint, this distance being the Radius.

Supported Platforms

Windows, Solaris, Linux

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.

Interfaces

Interfaces Description
ICircularArc Provides access to members that control properties of circular arcs.
IClone (esriSystem) Provides access to members that control cloning of objects.
IConstructCircularArc Provides access to members that construct a circular arc using other geometries and values.
IConstructCircularArc2 Provides access to members that construct a circular arc using other geometries and values.
IConstructCircularArc3 Provides access to members that construct a fillet using a point on the fillet.
ICurve Provides access to properties and methods of all 1 dimensional curves (polylines, segments, boundaries of polygons, etc.).
ICurve2 Provides access to members that extend the functionality of one dimensional curves.
ICurve3 Provides access to members that extend the functionality of one dimensional curves.
