Plane Create By Three Points Method

Creates a Plane object passing through three points supplied as arguments.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public static Plane CreateByThreePoints(
	XYZ point1,
	XYZ point2,
	XYZ point3
)

Parameters

point1 XYZ
First of the three points that define a unique plane. The created Plane object will pass through these points.
point2 XYZ
Second of the three points that define a unique plane.
point3 XYZ
Third of the three points that define a unique plane.

Return Value

Plane
Exceptions
Exception Condition
ArgumentException The input point lies outside of Revit design limits.
ArgumentNullException A non-optional argument was null
ArgumentsInconsistentException Throws if the input points do not define a unique plane. This is typically caused by points being too close to each other, or all three points being on or close to a straight line.
Remarks
The points supplied as arguments must fully define a plane: they may not lie on a straight line or be too close to each other. The points must lie within the Revit design limits. This function does not guarantee a specific parameterization of the created Plane. Use Plane.Create(Frame) to enforce a specific parameterization of the created Plane object. All three points are expected to lie within the Revit design limits IsWithinLengthLimits(XYZ) .
