Observation

Many candidates attempted this question and their perfomance was not okay.
The soolution  with the step-by-step requirement for the question, the lack of knowledge of which made the students not to perform well, is given below.

DRAWING THEA GIVEN VIEW OF A TRUNCATED HEXAGONAL PYRAMID,ITS FIRST ANGLE ORTHOGRAPHIC PROJECTION VIEWS AND THE SURFACE DEVELOPMENT OF ITS GIVEN SEAM

MAJOR REQUIREMENTS INVOLVED IN THE SKETCH OF THE REQUIRED ORTHOGRAPHIC VIEW
 (b)       PLAN
-           Projecting down from the cut surface (top) to intercept the diagonals of the hexagon
-           Projecting down from the cut surface (lower) to intercept the diagonals of the hexagon
                              -           Joining the point to complete the plan

(c)       END ELEVATION
-           Projecting lines from the elevation and plan
-           Drawing the end elevation E, F, G

(d)       SURFACE DEVELOPMENT
-           Drawing horizontal lines from the cut surface to touch the side AB
-           Drawing the radial lines (5 no arcs) for development with centre A and using each point on AB as radius
-           Stepping the base edges along the arc from B and joining to the apex
-           Locating the points of the cut surfaces (top and lower) being the intersection of the arcs and the radiating lines from A
-           Joining the points to obtain the surface development
-           Neatness and quality of linework
