Create Method (XYZ, Double, Double, Double, XYZ, XYZ)

Arc Create(XYZ, Double, Double, Double, XYZ, XYZ) Method

Creates a new geometric arc object based on center, radius, unit vectors, and angles.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.3.0.0 (25.3.0.0)
Syntax 
public static Arc Create(
	XYZ center,
	double radius,
	double startAngle,
	double endAngle,
	XYZ xAxis,
	XYZ yAxis
)

Parameters

center XYZ
The center of the arc.
radius Double
The radius of the arc.
startAngle Double
The start angle of the arc (in radians).
endAngle Double
The end angle of the arc (in radians).
xAxis XYZ
The x axis to define the arc plane. Must be normalized.
yAxis XYZ
The y axis to define the arc plane. Must be normalized.

Return Value

Arc
The new arc.
Exceptions
Exception Condition
ArgumentNullException A non-optional argument was NULL
ArgumentOutOfRangeException xAxis is not length 1.0. -or- yAxis is not length 1.0. -or- The given value for radius must be between 0 and 30000 feet.
ArgumentsInconsistentException The vectors xAxis and yAxis are not perpendicular. -or- Start angle must be less than end angle. -or- Curve length is too small for Revit's tolerance (as identified by Application.ShortCurveTolerance).
Remarks
If the angle range is equal to or greater than 2 * PI, the curve will be automatically converted to an unbounded circle.
