It was observed that many candidates:

            -  failed to show sectional lines on plan;
            -  lacked knowledge of representing building roof both in type and pitch;
-  failed to prepare doors and windows schedules in accordance with the conventional format.

To overcome these weaknesses, candidates should be:

-  given ample drawing assignments involving various lines used in building drawing and their applications;
-   exposed to building working drawings produced by qualified professionals such as architects and structural engineers;
-  well acquainted with types of roof and their structures.
