This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1908 Excerpt: ...to find its horizontal trace. See Fig. 76. SOLUTION I.--Exact Method.--Let the angle with the P.P. be 50. Following the method described in section 107, if any horizontal line of direction S.P.1 lT.P.2 is drawn making the required angle with the P.P., it must cut the P.P. in a point on a circle having its center at C. V. If /. T.A. is the initial trace of the given plane, then the vanishing-trace must be parallel to it and also tangent to the circle bed. Any point a in the initial trace can be taken as the initial point of the horizontal trace. The latter must vanish in V.P.1, where the vanishing-trace intersects the horizon. Solution II.--The vanishing-trace, as before, must be found. If an auxiliary plane B is conceived to be passed perpendicular to the P.P. and to the given plane, the lines cut out in each of the latter two by the former will be at the angle to each other that the given plane is with the P.P. The vanishing-trace of the auxiliary plane will pass through C. V., which can be taken anywhere, and be perpendicular to the given initial trace. If the S.P. is rotated about the vanishingtrace of the auxiliary plane to the position S.P.2, then C. V. V.P.1 will be parallel to the line cut out on the P.P., and S.P.2 V.P.3 can be constructed parallel to the line cut out in the given plane, namely, a line at 50 to the P.P. V.P3 is the point in which this line of direction cuts the P.P., and will be one point in the vanishing-trace of the given plane, or, in other words, V.P.'6 would be the vanishing-point of all lines of greatest declivity of the plane A with respect to the P.P. From here on the process is the same as in the first solution. Approximate Method.--From an inspection of the above demonstration it can be seen that the radius of the circle t...
