Parallel projection {orthogonal projection, geometry} {orthographic projection, orthogonal} can have projection rays perpendicular to the plane. Orthogonal projection can be on horizontal plane {horizontal projection} {plan, projection}, vertical plane {elevation, projection}, or other planes {section, projection}. Plans {figured plan} can mark vertical distances from plane to figure.
