    Study Notes

    Shape and Angle Distortion

    • Perspective drawing makes objects appear more like what our eyes perceive, but introduces size and shape distortion.
    • Circular holes become ellipses.
    • Right angles become obtuse angles.
    • Multiview drawing creates multiple views of an object from different directions.

    Multiview Drawing

    • Multiview drawing is a set of related images created by viewing an object from different directions.
    • Adjacent views are needed to fully describe an object's height, width, and depth.

    Methods of Multiview Drawing

    • Revolve the object with respect to the observer.
    • The observer moves around the object.
    • Glass box concept.

    Glass Box

    • The glass box concept involves revolving the planes of projection to create different views.
    • The views include top, front, right side, rear, left side, and bottom.

    Relative Orientation of Views

    • The top view shows width and depth.
    • The front view shows height and depth.
    • The right side view shows height and width.

    Problem-Solving Steps for Multiview Drawing

    1. Identify object features.
    2. Represent each feature with lines.
    3. Match each line or area to a feature.
    4. Identify line or plane types (normal, inclined, or obliqued).

    Object Features

    • Edges are lines that represent the boundary of two faces.
    • Surface limits are lines that represent the last visible part of a curved surface.
    • Surfaces are areas bounded by edges or surface limits.
    • Surfaces can be plane or curved.
    • Prisms, cylinders, and spheres have no edges.

    Projection of Normal Lines and Planes

    • A normal line projects as a straight line in all views.
    • A normal plane projects as a straight line in a single view and as a plane in the other views.

    Projection of Oblique Lines and Planes

    • An oblique line projects as a straight line in one view and a sloping line in other views.
    • An oblique plane projects as a straight line in one view and a plane in other views.

    Projection of Curved Lines and Surfaces

    • A curve line projects as a curve in all views.
    • A curve surface projects as a curve in one view and a plane in another view.

    Transferring Depth

    • Direct measurement involves measuring distances between views.
    • Miter lines (at 45 degrees) allow for transferring depth.

    Projection of Objects with Curved and Plane Surfaces

    • Curved surfaces may be tangent or intersect with planes or other curved surfaces.
    • Intersection creates an edge and a line in the multiview drawing.
    • Tangential surfaces have no edge or line in the multiview.

    Line Convention

    • Line convention prioritizes visible lines over hidden lines, center lines, and construction lines.
    • Hidden lines should be joined to visible lines, except when extending from a visible line.
    • Hidden line intersections should form L, T, V, or Y corners.
    • Center lines start and end with long dashes and should not extend between views.
    • Short dashes of center lines in a circular view cross at the center of the circle or arc.
    • For small holes, a center line is represented by a thin continuous line.
    • Hidden lines and center lines should have consistent spacing with visible lines and each other.

    Types of Planes

    • Normal planes.
    • Inclined planes.
    • Curve surfaces.
