Intersect Method (Face, Curve)

Calculates the intersection of the specified face with this face and returns the intersection results.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 21.0.0.0 (21.1.1.109)

Syntax

C# 
public FaceIntersectionFaceResult Intersect(
	Face face,
	out Curve result
)
Visual Basic 
Public Function Intersect ( _
	face As Face, _
	<OutAttribute> ByRef result As Curve _
) As FaceIntersectionFaceResult
Visual C++ 
public:
FaceIntersectionFaceResult Intersect(
	Face^ face, 
	[OutAttribute] Curve^% result
)

Parameters

face
Type: Autodesk.Revit.DB Face
The specified face to intersect with this face.
result
Type: Autodesk.Revit.DB Curve %
A single Curve representing the intersection.

Return Value

  • FaceIntersectionFaceResult.Intersecting - One or more intersections were encountered.
  • SetComparisonResult.NonIntersecting - There is no intersection found.

Remarks

This is not a general-purpose function: it only works properly for simple configurations. For other configurations, it may return an incorrect result. Some configurations for which the function might return a correct result are:
  • A planar face that fully intersects another face in a single curve, when the other face is planar or cylindrical.
  • A cylindrical face that fully intersects another face in a single curve, when the other face is planar.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentNullException The face is a null reference ( Nothing in Visual Basic) .
Autodesk.Revit.Exceptions InvalidOperationException The intersection calculation fails.
