Note: When a line is parallel to V.P. and inclined at an angle of e to H.P., this inclination e will be

seen in the front view. e denotes always the true inclination with H.P.

3. Therefore from al draw a line at an angle of300 to xy and mark bl such that albl 50mm = true
   length.

To obtain the top view ab look from the top Tv:

Since the line is inclined to H.P., its projection on H.P. i.e., the top view will be in reduced length.

4. From bl draw a projector to intersect the horizontal line drawn from a at b, ab is the top view
   ofAB.

Problem: A line EF 60 mm long is parallel to VP and inclined 30° to HP. The end E is 10 mm above
HP and 20 mm in front ofVP. Draw the projections of the line.

Problem: The length of the fromtview of a line CD which is parallel to HP and inclined 30° to VP,

is 50 nun. TheendC of the line is 15 mm in front ofVP and 25 mmabove HP. Draw the projections

of the line and fmd its ture length.
