I am new to using Blender, I am wondering if there is a way to easily get the intersection path between two planes as an object. So far what I've done is use the intersect (knife) tool and then manually delete all the vertices, edges and faces until I'm left with just the path, but doing this is quite laborious with complex surfaces. Thank you very much for your ideas.
Edit:In the example image, I would look to get the marked area as a path.
