termine aQ, the projection of A in this view, bymaking a0m = a/, that is, equal to the height of A abovethe ground; and aQn = a/, that is, equal to the distance ofA in front of the vertical plane. Similarly determine b0 and join aQ£>0. Draw o^Q perpen-dicular to a0b0. Then o0c0 is the shortest… … Examples.—1. Draw the plan and elevation of any line 2\ long,which is inclined at 350 to the horizontal plane, and 250 to thevertical plane. 2. A line 2^ long has one end in xy, and is inclined at 300 and 400 respectively to the horizontal and vertical planes of projec-tion. Represent the line. 3.…
