Sheet 3: Orthographic Projections
Note:
Approximate time required to complete the problem neatly is
specified undereach.
Submit the home assignment at the beginning of the Drawing
Session. Practice the remaining problems roughly on a Sketch Book
before coming to the
Drawing Hall.
Home Assignment:
1. Using first angle projection, draw the front view, top view
and a suitable side view of the
objects shown in Figure 5 so as to capture all the details. The
arrow indicates the direction
from which the front view should be observed. [15 min]
2. Using third angle projection, draw the front view, top view
and a suitable side view of the
objects shown in Figure 5 so as to capture all the details. The
arrow indicates the direction
from which the front view should be observed. [15 min]
3. Using first angle projection, draw the necessary orthographic
views of the objects shown
in Figure 9 so as to capture all the details. The arrow
indicates the direction from which
the front view should be observed. [30 min]
4. Using third angle projection, draw the necessary orthographic
views of the objects shown
in Figure 10 so as to capture all the details. The arrow
indicates the direction from which
the front view should be observed. [30 min]
5. Figure 11 show the orthographic projections of two objects in
first angle. Neatly sketch
their pictorial views in freehand and then draw them in third
angle. [20 min]
6. Figure 14 show the orthographic projections of two objects in
third angle. Neatly sketch
their pictorial views in freehand and then draw them in first
angle. [20 min]
Drawing Hall Assignment:
1. Using first angle projection, draw the front view, top view
and a suitable side view of the
objects shown in Figures 1 and 2 so as to capture all the
details. The arrow indicates the
direction from which the front view should be observed.

2. Using third angle projection, draw the front view, top view
and a suitable side view of the
objects shown in Figures 3 and 4 so as to capture all the
details. The arrow indicates the
direction from which the front view should be observed. [15x2=30

3. Using first angle projection, draw the necessary orthographic
views of the objects shown
in Figure 7 so as to capture all the details. The arrow
indicates the direction from whichthe front view should be
observed. [30 min]
4. Using third angle projection, draw the necessary orthographic
views of the objects shown
in Figure 8 so as to capture all the details. The arrow
indicates the direction from which
the front view should be observed. [30 min]
5. Figure 12 show the orthographic projections of two objects in
first angle. Neatly sketch
their pictorial views in freehand and then draw them in third
angle. [20 min]
6. Figure 13 show the orthographic projections of two objects in
third angle. Neatly sketch
their pictorial views in freehand and then draw them in first
angle. [20 min]
