CreateByThreePoints Method

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

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 17.0.0.0 (17.0.484.0)
Since: 2017

Syntax

C# 
public static Plane CreateByThreePoints(
	XYZ point1,
	XYZ point2,
	XYZ point3
)
Visual Basic 
Public Shared Function CreateByThreePoints ( _
	point1 As XYZ, _
	point2 As XYZ, _
	point3 As XYZ _
) As Plane
Visual C++ 
public:
static Plane^ CreateByThreePoints(
	XYZ^ point1, 
	XYZ^ point2, 
	XYZ^ point3
)

Parameters

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

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) .

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException The input point lies outside of Revit design limits.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
Autodesk.Revit.Exceptions 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.
