Study Notes
Multiview Drawing Concepts
- Multiview Drawing depicts multiple two-dimensional views of a three-dimensional object for proper shape communication between designers and manufacturers.
- Every three-dimensional object has three dimensions: width, height, and depth; these dimensions define the object's size in space.
Orthographic Projection Techniques
- Orthographic Projection is a method to create multiview drawings by projecting features of an object onto an imaginary plane at right angles to the object's features.
- Visualizing an object inside a glass box helps understand orthographic projection; the object's features are projected onto the box's six walls.
Projection Planes and Lines
- Projection Plane, also known as the plane of projection, is the imaginary surface from which two-dimensional views are derived.
- Projection Lines are imaginary lines that help project the edges and features of a three-dimensional object onto the projection plane.
Drawing and Indicating Features
- The process starts with focusing on the front projection plane, projecting visible edges through projection lines, and connecting projected corners.
- Hidden edges in a multiview drawing are represented by dashed lines, termed hidden lines.
Selecting Orthographic Views
- Front view selection should prioritize the object's most natural use position, visibility of characteristic contours, and stability, while minimizing hidden lines.
Number of Orthographic Projections
- A single view may be sufficient for uniform shapes, while two views cater to symmetrical parts requiring additional depth representation.
Steps in Sketching Multiview Drawings
- Sketching a multiview drawing involves laying out boxes for views, using construction lines for geometry indication, marking visible edges with object lines, and identifying hidden lines.
Historical Example
- Leonard P. Karr designed a man-sized hunting blind resembling a goose, named Super Goose, in 1991, illustrating practical application in design.
