This may appear a repeat I followed a couple of threads although none of the responses appear to have resolved the issue. points appear to be in the same plane ie. Z =0
ie. Flatten before and after geometry.intersection
Definition attached, aim of the which is to generate a orthogonal grillage for a skew greater than 25 degrees.
I am running DynamoDS 1.1.0.2093 evaluation, (same issue with 1.2.2 in the office)
Geometry.intersect and Geometry.intersectall
Workflow

Determine extents of deck geometry shew greater than 25degrees

Use extents to generate parametric grillage lines/curves

Three sections require to capture different line divisions ie. triagular lead and trailing sections with the central rectangular sect

Generate lines longitudinal and transverse (efficiently eventually)

Generate intersections and capture pointsâ€¦vertices ?

Sort points according to Euclidean geometry ie. x then y then z

Capture and sort the points in 6 branch data trees due to 6 longitudinal lines/curves

Redraw lines longitudinal and transverse
My cunning plan has become unstuck at the Geoimetry points intersections.
