ITerrainArc

The arc object is similar to the ellipse object but with the additional ability to set start and end angles that define the arc.

	Properties
	Action	An IAction representing the operation that takes place when the object is clicked in the Project Tree.
	Attachment	An IAttachment representing the attachment behavior of the arc.
	EndAngle	Gets and sets the angle at which the arc ends.
	FillStyle	An IFillStyle representing the fill color and texture of the object.
	ID	Gets the ID of the object. (Inherited from ITerraExplorerObject)
	LineStyle	An ILineStyle representing the style of the object outline.
	Message	An IMessageObject representing the message object assigned to the object.
	NumberOfSegments	Gets and sets the number of segments the arc has.
	ObjectType	Gets an enum that identifies the type of the object. (Inherited from ITerraExplorerObject)
	Position	An IPosition representing the position and orientation of the object on the terrain.
	Radius	Gets and sets the radius of the arc.
	Radius2	Gets and sets the radius of the ellipse along its North-South axis.
	SaveInFlyFile	Gets and sets a Boolean that determines whether the object is saved in the Fly file. (Inherited from ITerraExplorerObject)
	StartAngle	Gets and sets the starting angle of the arc.
	Terrain	An ITerrainObject representing terrain properties including draw order and ground object status.
	TimeSpan	An ITimeSpan representing the timespan in which the object is visible on the terrain.
	Tooltip	An ITooltip representing the tooltip that displays when a mouse cursor is placed over the object in the 3D Window.
	TreeItem	An ITreeItem describing the representation of the object in the Project Tree.
	Visibility	An IVisibility representing the visibility of the object at different distances.
	Methods
	GetClientData	Gets an array of text strings assigned to each object global namespace. (Inherited from ITerraExplorerObject)
	GetParam	Reserved. Currently not used. (Inherited from ITerraExplorerObject)
	SetClientData	Sets an array of text strings assigned to each object global namespace. (Inherited from ITerraExplorerObject)
	SetParam	Reserved. Currently not used. (Inherited from ITerraExplorerObject)

EndAngle

Gets and sets the angle at which the arc ends. The arc is built going clockwise. The StartAngle and EndAngle are relative to the arc’s yaw and not to the North. Choosing a StartAngle of –90 degrees and an EndAngle of 90 degrees always gives you the upper half of an ellipse regardless of the direction that the arc is aligned to.

JavaScript
EndAngle

C#
double EndAngle { get; set; }

C++

HRESULT EndAngle([out, retval] double* pVal)

HRESULT EndAngle([in] double pVal)

NumberOfSegments

Gets and sets the number of segments the arc has. The more segments, the smoother and more circular it appears.

JavaScript
NumberOfSegments

C#
int NumberOfSegments { get; set; }

C++

HRESULT NumberOfSegments([out, retval] long* pVal)

HRESULT NumberOfSegments([in] long pVal)

Radius

Gets and sets the radius of the arc in meters.

JavaScript
Radius

C#
double Radius { get; set; }

C++

HRESULT Radius([out, retval] double* pVal)

HRESULT Radius([in] double pVal)

Radius2

Gets and sets the radius of the ellipse along its North-South axis, in meters.

JavaScript
Radius2

C#
double Radius2 { get; set; }

C++

HRESULT Radius2([out, retval] double* pVal)

HRESULT Radius2([in] double pVal)

StartAngle

Gets and sets the starting angle of the arc. The arc is built going clockwise.

JavaScript
StartAngle

C#
double StartAngle { get; set; }

C++

HRESULT StartAngle([out, retval] double* pVal)

HRESULT StartAngle([in] double pVal)
