Hello, I'm learning to model and I have lots of questions but right now I only need to know one thing. I've made 2 palm leaves and I've merged them. I want to destroy one of them now to have only one, but I can't delete 2 of the points I don't know why. Here's the pic: I want to delete red and blue points. I can delete red points but I can't with the blue ones. Yellow shows off the mesh I want to have.
