Q1. What should be the output diagram while the object [X] is rotated by -45° about the
local axis passing through point F (i.e. arbitrary point). Diagram must be shown in
graph copy.
Q2. Develop an auxiliary view showing the true shape of the triangular corner for the [X]
object. Diagram must be shown in graph copy.
Q3. Develop the trimetric view of the object [X] if the angle is formed by a  = 30°
rotation about the y-axis, followed by a  = 45° rotation about x-axis then plane of
projection onto the z=0 plane. Diagram must be shown in graph copy.
Q4. Develop the dimetric view of the object [X] if the foreshortening factor along z-axis
of ½. Diagram must be shown in graph copy.
Q5. Develop the trimetric view of the object [X]. Diagram must be shown in graph copy.
Q6. Determined the [X*] for an oblique projection (i.e. CAVALIER) if = -45° and +45°
with β = 45°. What effect will be on the [X*] if  will be as same as above but f =0.5
(i.e. CABINET). Plot the diagram also in GRAPH COPY.
Q7. Perform a perspective projection onto the z=0 plane of the [X] from the center of
projection Zc=10 on the z-axis. What will be effects while we translate it to the center
and then perform the same perspective projection? Plot all diagram in your graph
copy also.
Q8. Perform a perspective projection onto the z=0 plane of the [X] from the center of
projection at x= - 10 on the x-axis and y= -10 on the y-axis. What will be effects
while we translate it to the center and then perform the same perspective projection?
Plot all diagram in your graph copy also.
Q9. Perform a perspective projection onto the z=0 plane of the [X] from the center of
projection at x= - 10 on the x-axis, y= -10 and z= 10 on the y-axis. What will be
effects while we translate it to the center and then perform the same perspective
projection? Plot all diagram in your graph copy also.
