Problem 2. The top view and Front view of a hut is shown in figure 6 (a). The front face of the hut lies in  the picture plane. The station point is 60 mm in front of the PPP and  25 mm above the Ground plane. The central plane is 75 mm  towards the right of the vertical axis of the hut.  Draw the perspective projection of the hut.

Solution:  The solution  for the problem is shown in figure 6(b).  The step wise procedure for drawing the perspective view is discussed below:

• Draw the Front view and top view of the hut by the 3^rd angle projection technique.
• Draw PPP with face abcde in PPP. In the top view, locate station point S  60 mm below PPP and 75 mm towards the left of CP (left of edge bg).
• Locate station point S’ in the front view  by drawing vertical projector from S and 25 mm above GL.
• Join S to the corner points f, g, h, j, and k. The  points 1, 2 and 3 are the points where these line pierces the PPP.
• In the front view, draw lines joining S’ with corner points D, E, A, B, and C.
• Draw vertical projectors from points 1, 2, and 3 to meet these lines to obtain  the points J’, K’, F’, G’ and C’, respectively. Join the edges to obtain the perspective view.
