To quickly assess the difficulty of the text, read a short excerpt:
In (d), c is at (6", 6"). Lay off eg in (a) = cg in (d). Draw g h in (a) parallel to o x and equal to g h in (d). Proceed in a similar manner to find other points. (b) Draw the isometric projection of a vertical, hex- agonal prism, 3^" long, a side of whose base is 0. 75", intersected by a rectangular prism ij" long, the edges of whose base are 1. 25" hori- zontal and i" vertical, and which is parallel to one face of the hexagonal prism. The upper face of the intersecting prism is i" below the ...upper base of the hexagonal prism, ox, o y, and o z may be taken as the axes or parallel to them. In (b), c is at (9", 6"). A b in (b) is par- allel to o x, and h k parallel to o z. C k = c h in (b) equals ck = ch in (c). Ez in (b) = i". Eg in (b) = e g in (c), etc. In (c), c is at (6", 2. 25"). ISOMETRIC PROJECTION PLATE 31. 85 86 MECHANICAL DRAWING. 56. Oblique Projections. All the preceding projec- tions have been orthographic, that is, the projecting lines of the different points have been perpendicular to the plane upon which the drawing is made.
