SECTIONAL VIEW – PARALLEL TO H.P AND PERPENDICULAR TO V.P
A cube of 40 mm sideis cut by a horizontal section plane, parallel to
H.P at a distance of 15 mm from the top end. Draw the sectional top
view and front view

SECTIONAL VIEW – INCLINED TO H.P AND PERPENDICULAR TO V.P
A square prism of base side 50 mm and height of axis 80 mm has its
base on H.P, it is cut by a section plane perpendicular to V.P and
inclined to H.P such that it passes through the two opposite corners of
the rectangular face in front. Draw the sectional Top View and Front
View. Find the angle of inclination of the section plane

SECTIONAL VIEW – PERPENDICULAR TO H.P AND INCLINED TO V.P
A square prism of base side 40 mm and height 70 mm is resting on its
rectangular face on the ground such that its axis is parallel to H.P &V.P,
it is cut by a section plane perpendicular to H.P &incllined to V.P at an
angle of 45° and passing through a point 10 mm from one of its ends.
Draw the sectional Front View and Top View

EXAMPLE: TRUE SHAPE PROBLEM
A square prism of base side 50 mm and height of axis 80 mm has its
base on H.P, it is cut by a section plane perpendicular to V.P and
inclined to H.P such that it passes through the two opposite corners of
the rectangular face in front. Draw the sectional Top View and Front
View and true shape of the section
