Technical Drawing - Exam Papers - Higher - 1995 - Paper 1Question 1GIven the horizontal and vertical projections of two planes ABC and ADE. A = 140 - 100 - 10 (a) Determine the line of intersection between the planes. (b) Determine the dihedral angle between the planes. (c) Draw the plan and elevation of the perpendicular from D to the plane ABC. Hence or otherwise, determine the inclination of AD to the plane ABC. (d) On a separate diagram, draw the projections of the skew lines AB and DE and show the projections of the shortest horizontal distance between them. ![]() |
