e directions of the axes given. First choose any pointin one of the lines, say, H, in axis A at (i), and proceed to find points in B and Cthat are at the same level, by lines from H perpendicular to C and B respectively.Then by rabatting the right angle contained by axes A and B, also by A and… … Fig. 75- If the incHnations of these given axes. Fig. 75, are required to be found, itwill be seen that a vertical plane containing one of them, say, axis A, will cut theplane of the others in the Hne RT, see (ii), and that HR is at right angles to RT,therefore the vertical semicircle on the line…
