A view of a surface that is neither parallel nor perpendicular to any of the principal planes in the viewing cube, is a. inclined C. normal b. oblique. d. un-interpretable. A normal view of a surface is one that a. is perpendicular to the line of sight. c. will produce an edge view in a single adjacent projection. d. displays the true size and shape of the surface (true length lines, etc.) e. all of the above. b. is parallel to the projection plane. Other techniques (besides the 45° miter line) are available for solving problems using the principles of orthographic projection. a. True b. False
