Can’t seem to figure anything out.. – Sketch 3D Review

I was SUPER excited when I found this app. My computer broke down and I have a real itch to create something again. But I can’t seem to figure a single thing out. I can’t find a tutorial anywhere on the internet about this app. I can’t figure out what the buttons do. I can’t even figure out how to select vertices, edges, or faces. I can’t figure out how to scale or rotate if I do have them selected. 4 stars just cause I know it can do many things, but I have absolutely no idea how to do them..
