I have the model from the bellow image and when I'm entering Edit mode, I can't see any vertices. How can I enable them? I want to remove some parts of it. If I add a simple cube, on that I can see them. All the tutorials I've seen start with them on and tell you how to move/delete, and none of them talk about the situation when they aren't showing. Does it have something to do with the model and it can't be changed?
This is the wireframe view:
