Question

A straight line PQ has the end P at 15 mm above the H.P. and 60 mm in front of the V.P., and the end Q is 45 mm above the H.P. and 10 mm in front of the V.P. If the end projectors are 55 mm apart, draw the projections of the line. Determine its true length and true inclination with the principal planes.​

Answer 1

Answer:

The distance between end projectors of line AB is 40 mm. The end point A is 15 mm above HP and 20 mm in front of the VP. The line is inclined 30° to the HP. Draw the projections if the true length of the line is 80 mm. Find its inclination with the VP. Take end point B is in I quadrant
