Assignment No. 3

Course name: Engineering Drawing (ES2302)


Assignment Topic: Projection of lines (Basics)

1. A 50 mm long line PQ is parallel to both the H.P. and the V.P. It is 25 mm in front of the
V.P. and 60 mm above the H.P. Draw its projections.
2. A 80 mm long line PQ has end P 20 mm above H.P. and 40 mm in front of the V.P. The line
is inclined at 30° to the H.P. and is parallel to the V.P. Draw the projections of the line.
3. An 80 mm long line PQ is inclined at 30° to the V.P. and is parallel to the H.P. The end P of
the line is 20 mm above the H.P. and 40 mm in front of the V.P. Draw the projections of the
line.
4. Draw the projections of a 70 mm long line PQ, situated in the V.P. and inclined at 30° to the
H.P. The end P of the line is 25 mm above the H.P.
5. A 60 mm long line AB is parallel to and 20 mm in front of the V.P. The ends A and B of the line are
10 mm and 50 mm above the H.P., respectively. Draw the projections of the line and determine its
inclination with the H.P.
6. The top view of a line measures 60 mm. The line is parallel to the V.P. and inclined at 45° to
the H.P. One end of the line is 25 mm in front of the V.P. and lies on the H.P. Draw its
projections and determine the true length.
7. A line AB 60mm long is situated in H.P and inclined to V.P at 30°. The end A is 20mm in
front of V.P, draw the projection of line.
8. The front view of 75 mm long line measures 55 mm. The line is parallel to H.P. and one of
its ends is in the V.P. and 25 mm above H.P. Determine the projection of the line.
9. A 60 mm long line PQ has its end P 20 mm in front of the V.P. The line is perpendicular to
the V.P. and 40 mm above the H.P. Draw the projections of the line.
10. Draw the projections of a 60 mm long line PQ, which is situated both on the H.P. and the
V.P. Also, determine the traces of the line.
