Question

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.

a. [projections not provided]
b. [inclination not provided]
c. [both]
d. [none]

Answer 1

To draw the projections of line AB and determine its inclination with the H.P., follow the steps provided, which involve constructing the top and front views and measuring the angle between AB and the H.P.

Step-by-step explanation:

To draw the projections of the line AB and determine its inclination with the H.P., we first need to know the measurements and orientations of the line and the reference planes. Given that line AB is 60 mm long and parallel to the V.P, with A and B situated 10 mm and 50 mm above the H.P respectively, we can proceed with the following steps:

1. Construct the top view by drawing a line parallel to the H.P, and 60 mm long, with one end 10 mm above the H.P and the other end 50 mm above the H.P.
2. Construct the front view by drawing a line parallel to the V.P, and 60 mm long, situated 20 mm in front of the V.P.
3. Connect the corresponding points of AB in the top and front views using construction lines.
4. Measure the angle between the line AB and the H.P to determine its inclination with the H.P.
