Answer 1

Answer:

. Draw the projection of the following points.

Point A which is 40 mm above HP and 55 mm in front of VP (First Quadrant)

Point B, which is 10 mm above HP and 15 mm behind VP.(Second Quadrant)

Point C, which is 25 mm below HP and 20 mm behind VP (Third Quadrant)

Point D, which is 20 mm below HP and 20 mm in front of VP(Fourth Quadrant)

Draw the projection of the following points lying on HP.

Point P which is 30 mm in front of VP.

Point Q which is 40 mm behind VP.

Draw the projection of the following points lying on VP.

Point R which is 30 mm above HP.

Point S which is 40 mm below HP.

4. Draw the projection of points on a common reference line. Take 20 mm distance between the projectors.

Point A is 10 mm above HP and 25 mm in front VP

Point B is 10 mm above HP and on the VP.

Point C is 25 mm below HP and 20 mm behind VP

Point D is 20 mm below HP and 20 mm in front of VP

Point E is on the reference line

Point F is on both HP and VP.

Figure shows the projections of different points. Determine the position of the points with reference to the projection planes. The distances marked are in millimeters.

A point C is on HP and 15 mm behind VP. Another point D is also on HP and 40 mm in front of VP. The distance between their projectors is 45 mm. Join their top views and determine the inclination of this line with XY line.

A point P is on HP and 20 mm in front of VP. Another point Q is also on HP and behind VP. The distance between their end projectors is 60 mm. Draw its projections if the line joining P and Q makes an angle of 600 with reference line. Also find the position of point Q.

A point A is 25 mm above HP and is in the first quadrant. Its shortest distance from the reference line XY is 45 mm. Draw the projections of the point and determine its distance from the VP.
