Arc Tool
An Arc Tool object can be configured as an elliptical arc or wedge. The Angle1 property specifies the angle of the starting point. When this property is set to 0, the starting point is horizontally to the right of center when the RotateAngle property is set to 0. A positive value indicates a clockwise rotation. The end point is defined by the Angle2 property.

To add an Arc Tool object, click on TheView where you want the first endpoint to be, and hold down the mouse to drag out the arc. Hold down the Shift key to create a circular arc. By default, a circular arc is subtended over 90 degrees.
If the IsWedge property is set to 1 - Yes, the Arc object’s end points are connected to the center. If IsWedge is set to 0 - No and the BackColor property is set to a value other than Automatic, the end points are connected to each other. This is because only closed objects can have a background (fill) color.
The fill color is specified by the BackColor property. When this property is set to Automatic, only the line is shown. The line color is specified by the ForeColor property. The line width is specified by the PenWidth property. The line style is specified by the PenStyle property. Only a solid line can have a PenWidth greater than 1 pixel.
An Arc Tool object does not show text. To show text in an arc, you must use both an Arc Tool object and a Text Tool object. However, an Arc Tool object can show the status of a point. To associate the object with a point use the point identifier properties to form a fully qualified CygNet tag string. The point identifier properties are [1:SiteService], [2:Point ID], [3:Long Point ID], [4:Facility ID], and [5:UDC]. If the object is on a templated screen, only use the [5:UDC] property.
The [AlarmElement] property can be set to show the point state color in the object’s Background Color, the Foreground Color, or not at all (None). When set to None, the color specified for each component is shown. If set to one of the other options, the component color is replaced with the point state color. Note that if the object is open in Edit mode (that is, the end points are not connected) and [AlarmElement] is set to Background Color, the end points will be connected in Run mode.
The [UseCustomStateColors] property enables the object to use its own custom point state colors. If set to 1 - Yes, the colors used are those defined by the object’s [CustomStateColors] property. If set to 0 - No, the colors are those defined by the TheView’s [CustomStateColors] property.
