2. No single dimension should be repeated except where unavoidable.
3. Mark the dimensions outside the drawing as far as possible.
4. Avoid dimensioning to hidden lines wherever possible.
5. The longer dimensions should be placed outside all intermediate dimensions, so
that dimension lines will not cross extension lines.

1. Students should identify and know the correct drawing of the following
dimensioning elements like Dimension lines, Extension lines, Leader
lines, Arrowheads.
2. Draw the figure in both, Aligned system & unidirectional system.

Assignment 5 Development of Surfaces
1. A regular hexagonal pyramid (40 X 75) mm is resting on H.P. on its base with
two edges of base parallel to VP. It is cut by AIP making 600
with HP and passing
through one of the corners of the base. Draw the development of the truncated
pyramid.
2. A pentagonal pyramid side of base 20 mm and height 35 mm is resting on HP on one
of its triangular faces. It is cut by AVP inclined to VP by 300
bisecting the axis.
Draw sectional elevation, true shape of section and draw the development of
lateral surfaces of the pentagonal pyramid. Assume axis of the pyramid parallel to VP.
3. A pentagonal pyramid has its base on the H.P. and the edge of the base nearer the
V.P., parallel to it. A vertical section plane, inclined at 45° to the V.P., cuts the
pyramid at a distance of 6 mm from the axis. Draw the top view, front view, and the
development of the surface of the remaining part of the pyramid. Base of the pyramid
30 mm sides; axis 50 mm long.
