The elevation length and plan length of line AB measures 50 mm and 60 mm respectively. The line AB is inclined at $30^0$ to the HP and the end A is 10 mm above HP and 20 mm in front of the VP. Draw the projections of line AB.

Q.10

Elevation Length = a’b2’ = 50 mm

Plan Length = ab1 = 60 mm

A is 10 mm above HP = a’ (↑) = 10 mm

A is 20 mm in front of VP = a (→) = 20 mm

θ = 30°

Self-explanatory.
