General Instructions

Student must attend all theory and practical classes and they need to carry Laptops to

each and every session. Both Fi rst angle & Thi rd angles will be followed. Cadian and

Autocad has same commands except one or two commands hence the student can follow the

autocad book for working on cadian. The student is expected to maintain the required

attendance failing which he/she will not be allowed to appear for the examination. During the

on-line exam, it is the responsibility of thestudent to save his/her files properly. The files

that are not saved as instructed will not be considered for evaluation.

Note:

1. The students are insisted not to change any softwares that are given to them with

laptop.

2. Exams:

Since the exams are conducted on laptop the laptop should contain

Windows XP

Cadian 2008

Laptops charged completely( should come for complete 2 Hours)

1.

The students with Other than above softwares are not allowed for Exams.

2. No Excuses.

3. It is student responsibility to make their laptops ready for Tests.

4. There Wireless connection has to be checked and repaired before getting to the Exam

Hall.

5. Battery problem, wireless not working, lap top purchased from outside reasons will not

be entertained.

6. Laptops with Vista and any other reasons will lead to cancellation of the Test for that

Drawing Limits:

Drawing limits are used to set the boundaries of the drawing. The drawing boundaries are

usually set to match the size of a sheet of drawing paper. This means that when the drawing is plotted

and a hard copy is made, it will fit on the drawing paper.

Standard Drawing Sheet Sizes are:

In millimeters

A4 210 X 297

A3 297 X 420

A2 420 X 594

A1 594 X 841

A0 841 X 1189

In Architectural (USA)

A 9 X 12

B 12 X 18

C !8 X 24

D 24 X 36

E 36 X 48

Generally, A4 and A are commonly used.

Dimensioning

The purpose of dimensioning is to provide a clear and complete description of an object. Acomplete set of dimensions will permit only one interpretation needed to construct the part.

Dimensioning should follow these guidelines.

Accuracy:correct values must be given.

Clearness:dimensions must be placed in appropriate positions.

Completeness:nothing must be left out, and nothing duplicated.

Readability:the appropriate line quality must be used for legibility.

The Basics: Definitions and Dimensions

The dimension line is a thin line, broken in the middle to allow the placement of the

dimension value, with arrowheads at each end

Dimensioned Drawing

An arrowheadis approximately 3 mm long and 1 mm wide. That is, the length is roughly

three times the width.


6/71


ACS/HY/2008-09- 6 -

An extension lineextends a line on the object to the dimension line. The first dimension line

should be approximately 12 mm (0.6 in) from the object. Extension lines begin 1.5 mm from the

object and extend 3 mm from the last dimension line.

A leader is a thin line used to connect a dimension with a particular area

Example drawing with a leader

A leader may also be used to indicate a note or comment about a specific area. When there is

limited space, a heavy black dot may be substituted for the arrows, as in figure. Also in this drawing,

two holes are identical, allowing the "2x" notation to be used and the dimension to point to only one of

the circles.

Where To Put Dimensions:

The dimensions should be placed on the face that describes the feature most clearly. Examples

of appropriate and inappropriate placing of dimensions are shown in figure

Example of appropriate and inappropriate dimensioning

ACS/HY/2008-09- 7 -

In order to get the feel of what dimensioning is all about, we can start with a simple rectangular

block. With this simple object, only three dimensions are needed to describe it completely .There is

little choice on where to put its dimensions.

Simple Object

We have to make some choices when we dimension a block with a notch or cutout (figure

Surface datum example ). It is usually best to dimension from a common line or surface. This can be

called the datum line of surface. This eliminates the addition of measurement or machining

inaccuracies that would come from "chain" or "series" dimensioning. Notice how the dimensions

originate on the datum surfaces.

Saving your drawing

When you save a drawing, your work is saved in a drawing (.dwg) file.

After you have saved your drawing for the first time, you can save it with a new name. In addition to

drawing (.dwg) files, you can also save a drawing in a Drawing Exchange Format (.dxf) file or a

drawing template (.dwt) file.

If you created your drawing using a template, saving the drawing does not alter the original template.

Orthographic Projections

Orthographic or Multiview Drawing

Imagine that you have an object suspended by transparent threads inside a glass box, as in figure .

The block suspended in a glass box

Then draw the object on each of three faces as seen from that direction. Unfold the box (figure)

and you have the three views. We call this an "orthographic" or "multiview" drawing.

The creation of an orthographic multiview drawing

Figure shows how the three views appear on a piece of paper after unfolding the box.

A multiview drawing and its explanation

Which views should one choose for a multiview drawing? The views that reveal every detail

about the object. Three views are not always necessary; we need only as many views as are required to

describe the object fully. For example, some objects need only two views, while others need four. The

circular object in figure requires only two views.

Isometric Drawing

The representation of the object in figure is called an isometric drawing. This is one of a family

of three-dimensional views called pictorial drawings. In an isometric drawing, the object's vertical

lines are drawn vertically, and the horizontal lines in the width and depth planes are shown at 30

degrees to the horizontal. When drawn under these guidelines, the lines parallel to these three axes are

at their true (scale) lengths. Lines that are not parallel to these axes will not be of their true length.

Sectional Views

Sections are used to show interior details clearly.

A cutting-plane line shows where object was cut to obtain the section view.

Cross hatching in the section view shows the solid surface of the object which was cut through

to produce the section.

Section views may replace standard views.

Conventional practices, such as not showing hatching on ribs and webs, help make sections

easier to interpret correctly.

Imagine the object cut through by the cutting plane. Think of the two halves pulled apart and a

view looking on to the cut half.

DEVELOPMENT OF SURFACES

The development of surface of an object means the unrolling or unfolding of all surfaces of the

object on a planeEvery line on the development should show the true length of the corresponding line on the

surface which is developed.

METHODS OF DEVELOMENTS:

I. PARALLEL-LINE METHOD:It is used for developing prisms and single curved

surfaces like cylinders, in which all the edges /generators of lateral surfaces are parallel to

each other.

II. RADIAL-LINE METHOD:It is employed for pyramids and single curved surfaces like

cones in which the apex is taken as centre and the slant edge or generator as radius for its

development.

III. TRIANGULATION METHOD: Itis used for developing transition pieces.

IV. APPROXIMATE METHOD:It is employed for double curved surfaces like spheres, as

they are theoretically.

APPLICATIONS

The knowledge of development of surfaces is essential in many industries such as

Automobile, Aircraft, Ship-building, Packaging and Sheet-metal work.

plates are marked and cut according to the developments.

mm.

3. Draw the development of the complete surface of a G.I. cylindrical drum with lid. Diameter is

30 cm and the height is 1.6 times the diameter. Take a suitable scale.

4. Develop the complete surface of a cube of 35 mm side.

5.
