Questions & Answers
Q: What are the parameters required to solve the problem of projecting lines inclined to both planes?
The parameters required are the length of the line, the inclination of the front view with the x-y line, the position of point A relative to the horizontal and vertical planes, and the inclination of the line with the vertical plane.
Q: How do you locate point A in the projection?
Point A can be located by measuring the given distances above the horizontal plane and in front of the vertical plane.
Q: How do you find the locus of point B?
The locus of point B is found by drawing a light horizontal line through point B dash parallel to the x-y line.
Q: How is the true length of the line determined?
The true length of the line is determined by projecting a line parallel to the x-y line in the front view and finding its intersection with the inclined line. This intersection point is then projected down to the top view.
