Finding intersectionpoints coordinates

Geometry
1

Hi,

I’m trying to find the coordinates of the intersections between a Revit systemfamily (pipes/ducts) and created XY planes by level. I.e. i’m trying to find the points where my vertical pipes and ducts are intersecting when crossing levels.

I wrote a dynamo script trying to find these points. I managed to get as far as finding the intersections.

With Geometry.Doesintersect (cross product) i get the booleans when a pipe or duct is intersecting a level.
With Geometry. Intersect i get Surfaces.

But where to go now? How can i find the coordinates of the intersecting points?

Many thanks for help!

Hi Mark,

It seems like you’re using the Element.Geometry node to get the pipe’s geometry and use that for clashing. A better approach would be to just get the pipe’s location (this will return a curve) and then use that as input for the Geometry.Intersect nodes.
That way it will return a point as result, but it will also be a lot faster.
