found will pass through the centreof the sphere. Thus, by joining ab and ab the chord AB \s represented, andfrom the centre point of it, pp, a horizontal line PQ is drawn as a horizontal lineon the plane perpendicular to AB, giving the point q as its V.T. through whichthe V.T. of the AB plane may… … Fig. 59. plane ^C is next found, and then the intersection of plane AB with one of these(conveniently AC m this.solution), and the plans of the intersections obtainedcross each other in the plan of the centre of the sphere. Likewise the elevationsof the intersections cross each other in the…
