Hi @ansarimdnazir,

In general, the approach would be to get the geometry of all of the elements and then use the Geometry.Intersect node to find the intersection points. However, the process for initially getting the geometry into Dynamo depends on what types of elements you are working with. What all do you have?

Jacob - FYI that link is for ObjectARX (C++) and not the .NET API (C#, VB). So the correct place to reference would be here when dealing with Dynamo.

Ah, that’s what I get for posting the first ‘intersects AutoCAD api’ search result I could find. Thanks for the correction!
