Axonometric Projection Questions

• In this type of projection, each of the axes has different ratios of foreshortening:
• This type of axonometric drawing has equal foreshortening along two axis directions and a different amount on the third axis:
• The edges of a cube in isometric projection make angles of this many degrees with each other:
• In isometric projection, all distances are approximately this percentage of their true size:
• Lines of an isometric drawing that are not parallel to the isometric axes are called this:
• Angles project true size only when the plane containing the angle and plane of projection are this:
• Isometric drawings, unlike isometric projections, are drawn using the full length measurements of the actual drawing and lack foreshortening.
• If a circle lies in a plane that is not parallel to the plane of projection, the circle projects as an ellipse.
• If a circle lies in a plane that is not parallel to the plane of projection, it still projects as a circle.
• Nonisometric lines are equally foreshortened.
• An isometric drawing is about 50% smaller than the isometric projection.
• In isometric drawings, hidden lines are typically omitted.
• Dimetric drawings have different foreshortening along all three axis directions.
• Parallel partial ellipses equally spaced at the symbolic thread pitch can be used to represent screw threads.
• In isometric drawings, an angle may project to appear larger, but never smaller than the true angle depending on its position.
• Isometric sectioning is typically not used when drawing open or irregularly shaped objects.
• Isometric drawings have equal foreshortening along each of the three axis directions.
