To quickly assess the difficulty of the text, read a short excerpt:
Ac- cording to analysis this is the revolved position of a line of the required plane. In true position this line pierces H at d p a point in the required horizontal trace ; and pierces V at ', a point in the required vertical trace. The two traces S-s f and S-s 1 are now located. The element of tangency is that one determined by the point K. Since through O H another straight line may be drawn tangent to the circle c w another plane answering the conditions of the problem may be constructed. C...heck. Through some point of the element of tangency draw a profile plane cutting from the cylinder a circle. A rectilinear tan- gent to this circle at the point assumed is a line of the required plane and should pierce H and V in the traces already located. 308. Problem 184. Given a cylinder in the third quadrant whose axis is oblique to H and V and whose base is a circle on V ; required to assume a point without the surface and to draw through this point a plane tangent to the cylinder.
