How do I delete the overlapping part


My problem is that I want to insert a gem into the ring, but I don’t know how to delete the part that inserts into the ring. It’d be great if someone can help me! :wink:

If Boolean does not work, it means that the ring part is not a solid object. You can try to use the split command. When two surfaces intersects you can use them to split each other. Make an extra copy of each object, split faces, delete what you don’t want and join the right faces again afterwards. Hope this work…
