Engineering Graphics GE 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 C.R.ENGINEERING COLLEGE Alagarkovil, Madurai I - SEMESTER LECTURE NOTES

14 C.R.ENGINEERING COLLEGE
Engineering Graphics GE 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 C.R.ENGINEERING COLLEGE Alagarkovil, Madurai I - SEMESTER LECTURE NOTES

15 C.R.ENGINEERING COLLEGE
Engineering Graphics GE 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 C.R.ENGINEERING COLLEGE Alagarkovil, Madurai I - SEMESTER LECTURE NOTES
