In the attached image, I am trying to intersect and recluster two vertical plates: the red highlighted one and the other blue plate which is just perpendicular to it as shown in the image. . When I am selecting two plates and right click, I can see the option of intersect and recluster. If I do that, it just changes the plate numbers but does not divide the red highlighted plated into 2. Why is this occurring? What should be the way out?
