Technical Drawing
P02/B Q1. The candidates were given parts for a Bearing Housing to assemble to produce a
Front Elevation and a Sectional End Elevation (Full Section) along a specific
Cutting Plane.
Comments on CSEC® Technical Drawing P02/B Q1
 The parts were assembled well (correct) and showed proper alignment for orthographic
projection method used to include the pin positional in the correct direction.
 The outside and hidden details of the features were well represented on the Front Elevation
of the assembly.

9.  The candidate showed the sectional view of the assembled parts along the cutting plane as
indicated in the question.
 Line weights were appropriately applied for outline, hidden detail, centre line, dimensions
and hatching lines.
 Six dimensions were included to show the requested: radius; metric thread, diameter and
an overall dimension.
 The title scale and projection method were indicated in the required format.
 The web was properly represented in section
How this work could be improved:
 Hatching lines must vary in direction and width to represent different parts.
 The cutting plane should be placed on the view representing outside features in this case
the front elevation to show where the section was taken
 All parts featured in the Sectional view (along where the cutting plane passed) must be
hatched.
 The Bolt head will not be visible in the Section View.

10. The candidates were given parts for a Bearing Housing to assemble to produce a Front Elevation
and a Sectional End Elevation (Full Section) along a specific cutting plane.
Comments on CSEC® Technical Drawing P02/B Q1
 The Sectional End Elevation was also an accurate representation as required by the given cutting plane.
 The cutting plane was shown on the Front Elevation to indicate where the section was taken.
 The requested six dimensions were shown to include the: metric thread, radius, diameter and overall
dimension.
 The web was properly represented in section.
 The Title, scale and projection method was stated in the requested format.
Weaknesses:
 Line weights for dimension lines/extension lines were not appropriate.
 The line to show the cut hole in the bearing cap in section was missing.
