CurveIntersect(Curve, IntersectionResultArray) Method

Note: This API is now obsolete.

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

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 26.0.4.0 (26.0.4.0)
Syntax

[ObsoleteAttribute("This method is deprecated in Revit 2026 and may be removed in a later version of Revit. Use the new Curve.Intersect method with CurveIntersectResultOption.Detailed. Note also that the updated method has improved handling of certain edge cases.")]
public SetComparisonResult Intersect(
	Curve curve,
	out IntersectionResultArray resultArray
)

Parameters

curve  Curve
The specified curve to intersect with this curve.
resultArray  IntersectionResultArray
Provides more information about the intersection.

Return Value

SetComparisonResult
  • SetComparisonResult.Overlap - One or more intersections were encountered. The output argument has the details.
  • SetComparisonResult.Subset - The inputs are parallel lines with only one common intersection point, or the curve used to invoke the intersection check is a line entirely within the unbound line passed as argument curve. If the former, the output argument has the details of the intersection point.
  • SetComparisonResult.Superset - The input curve is entirely within the unbound line used to invoke the intersection check.
  • SetComparisonResult.Disjoint - There is no intersection found between the two curves.
  • SetComparisonResult.Equal - The two curves are identical.
Exceptions
ExceptionCondition
ArgumentNullException Thrown when the specified curve is .
InvalidOperationException Thrown when failed to calculate the intersection.
Remarks
The array of the intersection results contains one entry for each point where curves intersect. The following is the meaning of IntersectionResult members:
  • XYZPoint is the evaluated intersection point
  • UVPoint.U is the unnormalized parameter on this curve (use ComputeNormalizedParameter to compute the normalized value).
  • UVPoint.V is the unnormalized parameter on the specified curve (use ComputeNormalizedParameter to compute the normalized value).
