What are circular and radial profiles when marking out?

Circular profiles refer to the outline or shape of an object that is round or cylindrical, often used in marking out to ensure accuracy in creating circular features. Radial profiles, on the other hand, involve measurements or markings that extend outward from a central point, resembling spokes on a wheel. Both profiles are essential in machining and fabrication processes to achieve precise geometries. They help in setting up tools and guides for cutting, shaping, or constructing parts accurately.
