Projection of Lines
1. A and B are the ends of a straight line AB. The end A is 65mm above HP and 40mm
infront of VP. The end B is 15mm above HP and 75mm infront of the VP. The distance
between the projectors along XY line is 65mm. Draw the projections of the line AB and
determine its inclination with HP and VP.
2. The top view of a 80mm long line AB measures 55mm, While the length of its front view
is 70mm. Its one end is 15mm in front of V.P. and is in HP. Draw its projection and
determines its inclination with HP & VP.
3. A line AB, 75mm long, has one end A in VP. Other end B is 15 mm above HP and 50
mm in front of VP. Draw the projections of the line when sum of it’s Inclinations with
HP & VP is 90o, means it is lying in a profile plane. Find true angles with reference
planes.
4. Draw the projections of a line AB, 90mm long, its midpoint point M being 50mm above
the HP and 40mm infront of the VP. The end A is 20 mm above the HP and 10 mm
infront of the VP. Find the inclination of the line with the HP and the VP.

Application of Lines
1. A picture frame 2m wide & 1m high is to be fixed on a wall railing by two straight wires
attached to the top corners. The frame makes an angle of 40 o with the wall & the wires
are to be fixed to a hook on the wall on the center line of the frame & 1.5m above the
railing. Find the length of the wires & angle between them.
2. Three lines OA, OB and OC are 25mm, 40mm and 35mm respectively meeting at O at
angles of 1200 each other, forms the top view of a tripod stand. The point O is 60mm
above HP. Draw the projections of the tripod and determine the true lengths of the legs of
the tripod.
3. Two points A and B are 6m and 9m above ground are seen at angles of depression of 60 o
and 45o respectively from the top of hill 15m above ground. When observed from hill, A
is seen towards North and B is seen towards South-West. Find slope and length of road
AB.
4. Two oranges on a tree are respectively 1.8m and 3m above the ground, and 1.2m and
2.1m from a 0.3m thick wall, but on the opposite side it. The distance between the
oranges, measures along the ground and parallel to the wall is 2.7m. Determine the real
distances between the oranges.
