(/) To draw a series of uniform circles the centers of which lie in the same straight line and plane. Fig. 21 illustrates a number of uniform circles with centers in a common straight line, drawing A being a mechanical drawing and drawing B an isometric drawing. .-r Fig. 21. To construct the isometric drawing, first consider one circle only, as, for example, the circle r-l-s-1 of drawing Aj and draw the isometric representation of this circle by the approximate method [Article 13 (a)], as shown... in drawing B by the parallelo- gram a-b-cr-d, the radii /, g, h, and i, and the ellipse r-l-s-1. Second, extend the center line r-s, the lines a-b and d-c, and through the points x and y draw lines parallel to the above lines, all as shown by the line s-Sj and the dashed lines b-m, c-p, x-^ri and y-o, respectively. Third, lay off on the line d~p the distances d-di, and dj-dj equal to the length e, the distance between centers of the circles; and, with a radius equal to radius h and the points d^ d^ sus centers, describe the arcs 2-Si _ Digitized by VjOOQLC 26 ISOMETRIC DRAWING and 3-S2 (parallel to the arc 1-s).
