Curve.Intersect(Curve, IntersectionResultArray%)
No longer obsolete in 2022 (was obsolete in 2026)
curve Curve The specified curve to intersect with this curve.
resultArray IntersectionResultArray% Provides more information about the intersection.
→ returns 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.
