Important guidelines for students:

1. Always be punctual in time. Latecomer won’t be permitted without solid reason.2. Before starting each sheet, signature of concern batch teacher should be taken on

the sheet without fail; else no credit would be given to that practical sheet.

3. Students should bring the drawing sheet ready for the practical. The borderlines andTitle block should be drawn on the drawing sheet before coming for the practical.

4. Before starting each sheet in the college, each student will have to ensure that thework in the sketch Book pertaining to that sheet is completed in all respect; else thestudent will not be allowed to start his work in the sheet.

5. Batch wise problems will be drawn on the sheet in the scheduled practical turn inthe drawing hall only.

6. Any data written on the sheets should be in the block (CAPITAL) letters only.7. All problems of all sheets should be drawn by first angle projection method if not

specify.

8. Name and ID No. Should be written on sheet in the title block with the ball pen.9. Student must come with all Drawing Equipments & Materials for laboratory work

Conversion of Units for Reference:

1µ (1 micron) = 0.000001 m (10-6 m)

1 mm (1 millimeter) = 0.001 m (10-3m)

1cm (1 centimeter) = 0.01 m (10-2 m)

1 dm (1 decimeter) = 0.1 m (10-1 m)

1dam (1 decameter) = 10 m

1 hm (1 hectometer) = 100 m (102 m)

1 km (1 kilometer) = 1000 m (103 m)

1 Mile = 8 Furlongs

1 Furlong = 220 Yards

4. Dimensioning System:

General Principles:

1. All dimensions should be detailed on a drawing.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.

Elements of dimensioning:

1. Students should identify and know the correct drawing of the followingdimensioning elements like Dimension lines, Extension lines, Leaderlines, 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 passingthrough one of the corners of the base. Draw the development of the truncatedpyramid.

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 lateralsurfaces 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 theV.P., parallel to it. A vertical section plane, inclined at 45° to the V.P., cuts thepyramid at a distance of 6 mm from the axis. Draw the top view, front view, and thedevelopment of the surface of the remaining part of the pyramid. Base of the pyramid30 mm sides; axis 50 mm long.

4. A pentagonal pyramid, side of the base 30 mm and axis 75 mm is resting on its baseon the HP with one edge of base inclined at 30° to VP. It is cut by a section planeperpendicular to the VP, inclined at 40° to the HP and passing through a point on theaxis 20 mm above the base. Draw the development of the surface of portion of thepyramid containing the major portion of the base.

5. Front view of the frustum of a right circular cone, diameter of base 44 mm andheight 50 mm, is 30 mm in height. It has an equilateral triangular of side 20 mmthrough cut in such a way that base of that triangle is parallel to base of frustum and5 mm above the base. Draw its front and top views. Also draw the development ofits lateral surface.
