MALAVIYA NATIONAL INSTITUTE OF TECHNOLOGY JAIPUR DEPARTMENT OF CIVIL ENGINEERING (2017-18 Odd Semester) COMPUTER AIDED ENGINEERING DRAWING ASSIGNMENT 3: PROJECTION OF LINES – II (Batch C) 1. A line, AB, of length 75 mm has its end A located on HP and end B in VP. The line is inclined 30 to HP and 45 to VP. Draw its projections and determine its traces if it lies in the third quadrant. 2. A line, MN, inclined 40 to VP, has its ends 50 mm and 20 mm above the HP. If the length of the elevation is 65 mm, and its VT is 10 mm above the base line, determine its true length, inclination with HP, and the distance from the xy line at which it intersects the horizontal plane. 3. The ends of a line, PQ, are on the same projector. P lies 30 mm below HP and 15 mm behind VP while Q lies 55 mm above HP and 45 mm in front of VP. Determine the true length of PQ, its angles of inclination with the reference planes, and its traces. 4. Two lines, RS and RT, make an angle of 120 between them in the plan and elevation. RS is parallel to both the reference planes. Find the true angle between RS and RT.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
