15. Table 1-1 lists finished format sizes. Looking in the category of "flat sizes" and under the column headings of
height, length, and margin, it can be seen that a flat size drawing with a height of 22 inches, length of 34
inches, and .50-inch margin is size D. (para 1-10,a) (table 1-1)
16 Information usually found in the title block will be name and address of preparing agency, title of drawing,
drafting record, authentication and date, scale and specification number, and drawing number and sheet
number for multiple-sheet drawings. (para 1-10,b)
17. Since b'-d' of surface A is not parallel to any of the three orthographic views, none of the three views shows
line b'-d' in true length. In order to show the surface in true length and shape, an auxiliary view in required.
(para 1-13,b)
18. Line f'-h' on the oblique drawing is line s-u in the right side view and line d-e in the front view. Since this line
is parallel to the font and right side planes of projection, it will project in true length. Line f'-h' appears as a
dot (point h) in the top view. (para 1-13,b)
19. Line v-x in the right side view is line c'-e' on the oblique drawing. It can be seen that line c'-e' is line k-l in
the top view. (para 1-13,b)
20. On the five surfaces shown, only surfaces B, C, and D are shown in true length and shape in at least one view.
Surfaces B and D are true length and shape in the top view and surface C is true length and shape in the right
side view. Surface A inclines to all three planes and cannot be shown in true length and shape. Surface E
inclines to the front and right side views. Line a'-b' of surface E is shown in true length in the top view (line
g-j), but the shape of surface E cannot be seen in the top view. (para 1-13,)
