3. Mid-sem Examination: Preparation and readiness
Date – September 23, 2018
Venue: Drawing Hall
Time:
Slot-I: 8:00 AM to 10:00 AM; Sections A1 to A7
Slot-II: 10:30 AM to 12:30 PM; Sections A8 to A14
Be seated 15 mins before the start of exam
Bring I-card and required drawing instruments
Do not bring calculators or mobile
Your bag should have only drawing instruments
No paper, notes, any sheets or anything related to exam

4. Simple Object and Concept
Results of section at A-A will be reflected in the front view
Results of section at B-B will be reflected in the side view
Observe – (i) How to show section plane and what arrow means
(ii) Hatching to differentiate solid and void/spaces

5. Spacing in hatch line 1.5 to 2 mm Do not measure by eye only.
Show three different pieces
In section (change in direction)
Line to indicate cutting plane
- use little longer dashes
Spacing in hatch line 1.5 to 2 mm
Do not measure by eye only.
Try drafters edge.

6. Full Section with OffsetA A
Section A-A

7. Why Half section?

9. Full Section

10. SV- Section FV
Half Section A-A

11. Showing cross section To save space Rotated Section
Rotate the section about vertical axis by 90 deg,
Depth shown in width

12. Rotated section as broken view – when?
What if height of section view interferes with the view

13. Removed Sections - same purpose as rotated section
But for clarity remove the section and show it outside the main views

15. Example:
Do not show hidden lines in
Section; prefer B over A
… but…this is not a rule

16. Show hidden lines in section
Prefer B over A – why?

17. Visible edges are shown after section; B is correct.
Adjacent Pieces… section line – change the angle of hatching lines

18. What not to section…
Shafts, bolts nuts, pins, rivets ….. Not sectioned
