Three Types of Pictorial Sketches Engineering Graphics

Engineering Graphics Sketching Circles and Arcs Diameter 2/3 of center distance Diameter Engineering Graphics Normally the circle only needs to be proportional to the other surfaces of a sketched object. Care should be taken to place the center of the circle as accurately as possible and the lengths representing the diameters should be shown as equal.
