Sketching Multiview Drawings
Multiview Drawing A multiview drawing is one that shows two or more two-dimensional views of a threedimensional object. Multiview drawings provide the shape description of an object. When combined with dimensions, multiview drawings serve as the main form of communication between designers and manufacturers. 2008 Autodesk

Width, Depth, and Height All three-dimensional objects have width, height, and depth. Width is associated with an object’s sideto-side dimension. Height is the measure of an object from top-to-bottom. Depth is associated with front-to-back distance. 2008 Autodesk

Orthographic Projection Orthographic projection is a technique that is used to create multiview drawings. Orthographic projection is any projection of the features of an object onto an imaginary plane of projection. The projection of the features of the object is made by lines of sight that are perpendicular to the plane of projection. 2008 Autodesk
Orthographic Projection The best way to understand orthographic projection is to imagine an object contained inside a glass box. 2008 Autodesk
Orthographic Projection There is a total of six glass walls surrounding the object. Each wall represents a projection plane onto which a twodimensional object view will be created. 2008 Autodesk
Projection Plane A projection plane, also referred to as a plane of projection or picture plane, is an imaginary surface that exists between the viewer and the object. The projection plane is the surface onto which a two-dimensional view of a threedimensional object is projected and created. 2008 Autodesk
Orthographic Projection Start by focusing only on the front projection plane. A person standing in front of the object would see only the five corners identified in black. 2008 Autodesk 2 3 1 4 5
Orthographic Projection Projection lines are used to project each corner outward until they reach the projection plane. 2008 Autodesk
Projection Lines A projection line is an imaginary line that is used to locate or project the corners, edges, and features of a three-dimensional object onto an imaginary two-dimensional surface. 2008 Autodesk
Orthographic Projection The visible edges of the object are then identified on the projection plane by connecting the projected corners with object lines. 2008 Autodesk
Orthographic Projection The orthographic projection process is then repeated on the other projection planes. 2008 Autodesk
Sketching a Multiview Drawing Given the overall dimensions of the object, a pencil, and a sheet of graph paper, a sketching multiview drawing can be easily done using points, construction lines, and object lines. 2008 Autodesk

forms through pen drawing input. In particular, 3D sketching based on traditional 2D perspective sketching techniques, such as repeated sketching in multiple perspectives [1, 11] and setting up reference 3D planes before sketching on them [2, 15, 16], has proven to be very powerful in the hands of professionally-trained designers.
