Tooling Cylinder

grabcad

This model was made using a center point circle using the origin as the point of revolution. The other partial circles were sketched to be extruded at different depths from the mid plane. For the corner slot, I sketched out the profile on the face of the model and used centerlines to align it in the correct position, then extruded. I then took advantage of the circular pattern tool to create the circles that revolve around the model.
