Types of Axonometric Projection • Isometric – has equal foreshortening along each of the three axis directions • Dimetric – has equal foreshortening along two axis directions and a different amount on the third axis • Trimetric – has different foreshortening along all three axis directions
Types of Axonometric Projection
Isometric Projection • The projections of the edges of a cube in isometric projection make angles of 120 degrees with each other
Isometric Projection • Lines of an isometric drawing that are not parallel to the isometric axes are called nonisometric lines – These lines are not equally foreshortened
Isometric Projection • Isometric scales can be used to draw correct isometric projections – All distances are approximately 80% of true size
Isometric Drawings • Isometric drawings, unlike isometric projections, are drawn using the full length measurements of the actual drawing and lacks foreshortening – The isometric drawing is about 25% larger than the isometric projection

Hidden Lines and Centerlines • Hidden lines are omitted unless they are needed to make the drawing clear • Center lines are shown if they are needed to indicate symmetry or if they are needed for dimensioning
Angles in Isometric • Angles project true size only when the plane containing the angle is parallel to the plane of projection • An angle may project to appear larger or smaller than the true angle depending on its position
Circles in Isometric • If a circle lies in a plane that is not parallel to the plane of projection, the circle projects as an ellipse • Ellipses can be constructed using offset measurements
Ellipses in Isometric • Approximate ellipses can be constructed from arcs

Screw Threads in Isometric • Parallel partial ellipses equally spaced at the symbolic thread pitch can be used to represent screw threads

Intersections
Spheres in Isometric
Isometric Sectioning • Isometric sectioning is useful in drawing open or irregularly shaped objects
Isometric Dimensioning • Isometric dimensions are similar to dimensions on multiview drawings but should match the pictorial style
