Your manager has ask you to write a report by describing the
advantages compare to other methods (like manual drawing and model making ) of
producing drawing electronically using CAD package . the advantages need to be
of the following :
Too many advantage
of using cad unlike manual drawing. With cad you can easily save on the
computer and can be accessed from anywhere with internet connection. Another
advantage CAD is there no chance of losing your documents unlike manual drawing.
Also cad drawing can be saved electronically without the paper; it is an
environmental friendly method.
The best of
virtually representing a structure is 3D drawing. 3D model can be create by
manual drawing but it wouldn’t look realistic as 3D model by auto cad. Creating 3d model it’s challenging and time
consuming, it’s much easier with auto cad.
The greatest advantage of CAD drafting over hand drafting is
the reduction in design time, which leads to reduced design costs. The cost of
purchasing and replacement cost of the equipment is expensive compared to
equipment used to draw manually.
Technology is invented to make peoples life easier, save time. Auto cad
is unimaginable faster than manual drawing. When manual drawing take several
hours of drawing something, but with cad it can be done in few mouse clicks.
With manual drawing all the objects drawn the size must be correct and
alignment. Even a small mistake can be catastrophic to the project .with cad
there is a lots of technique available to improve your accuracy in the project.
All drawing tools are electronic. Absolute accuracy can be
maintained. The computer keeps a record of all dimensions in the drawing.
Editing processes include the ability to copy, move, rotate, mirror and erase
drawing parts. Drawing storage is on a hard drive, memory stick, CD, DVD or
floppy disk rather than in a drawing folio. Hard copies can be produced in
colour and to a high professional standard. The drawings can be reproduced as
often and as quickly as you want.
Even though CAD very helpful still it has some disadvantages
such as some shapes that are difficult to draw using CAD software. Preferably
the computer equipment should be in a climate controlled, dust-proof
With manual drafting, you can separate information onto individual
transparent overlays. For example, a building plan might contain separate
overlays for its structural, electrical, and
With CAD, layers are equivalent to transparent overlays. As with
overlays, you can display, edit, and print layers separately or in combination.
You can name layers to help track content, and lock layers so they can’t
be altered. Assigning settings such as colour, line type, or line weight to
layers helps you comply with industry standards. You can also use layers to
organize drawing objects for plotting. Assigning a plot style to a layer makes
all the objects drawn on that layer plot in a similar manner.
Speed and Time – Technologies are invented to make our work easier,
save our time and to complete the work faster. AutoCAD is significantly faster
than the traditional method of manual drafting. It speeds up the task of
preparing bill of materials, reports, scaling etc. The tedious task of drawing
each line on paper can be done in few mouse clicks. As CAD software eliminates
repetitive iterations, a substantial amount of time is saved. In AutoCAD, data
describing a component or its family is associative in nature and hence
revisions are automatically made to all places the data is used.
Accuracy – In manual drafting, all the objects drawn
must be of correct size and alignment. Each object need to be manually verified
and dimensioned as the slightest error can be catastrophic to the entire
project. With CAD, there are numerous techniques available to obtain exact
dimensions thus leading to improved accuracy in the project.
Owing to the numerous benefits in
terms of speed, accuracy, data storage, revision CAD offers over manual
drafting, it has become a standard for the AEC industries.
Data storing and
Accessibility – One of the advantages of CAD drafting is that
the drawings need not be filed and stored in folder unlike in manual drafting.
CAD drafting can be easily saved on the computer server and can be accessed
from anywhere with internet connection. The chance of losing the documents is
higher in manual drafting. As CAD drawings can be saved electronically without the use of
paper, it is also an environment friendly method.
How CAD saves time
1. cntrl+1 :
This command brings up your object properties box. Depending on how you have
your workspace setup this one can be an important staple or only somewhat
2. cntrl+shift+c :
This brings up the copy with base point command. I personally use this shortcut
all the time, especially useful when used to copy spatially referenced line
work into another drawing. By using 0,0 as a base point and then again as the
insertion point your linework will be inserted in the same location spatially
in the new drawing.
3. pedit :
Brings up polyline edit command. Edit, create, and modify polyline properties
easily in the command line.
4. i :
Simply brings up the insert window. Use this command to save time inserting
blocks in your drawing. If inserting dynamic or attribute based blocks simply
repeat to insert again and again.
enter e enter : This one I guess is technically 2 combined. But it can
be entered so quickly and easily it almost becomes a second nature. Z brings up
the zoom command and E stands for extents. Pressing z enter e enter quickly
zooms your drawing to show the extents of your entire drawing. Very useful for
finding lost and runaway line work that may be hiding, as well as getting a full
view of your project.
The Time Factor
The greatest advantage of CAD drafting over hand drafting is
the reduction in design time, which leads to reduced design costs. The drafting
must create accurate drawings, and any error can have catastrophic results.
Drafters need more time for the desired results with hand drafting, as each
line has to be accurately measured and drawn. CAD software ensures total accuracy of measurement
with a few simple commands, thus saving time. CAD enables storing of earlier
design templates in the computer so the design process need not be
started from scratch for each new project. Existing templates can be customized
to fit requirements of the new project, reducing the design time.

Like most of Google’s software package, Sketchup is free for a basic

located Sketchup to be corresponding to autocad in its basic

Sketchup uses Google’s search powers to grab existing objects from an
internet cache, providing users with predefined shapes to incorporate

Google Sketchup hooks up to 3D Warehouse that contains a seriously large assortment

Computer-aided manufacturing (CAM)
is the use of software to control machine tools and related
ones in the manufacturing of work pieces.
But it is the most common; CAM may also refer to the use of a computer to
assist in all operations of a manufacturing plant, including planning,
management, transportation and storage. Its primary purpose is to create a
faster production process and components and tooling with more precise
dimensions and material consistency, which in some cases, uses only the
required amount of raw material (thus minimizing waste), while simultaneously
reducing energy consumption.
order to generate the actual model, CAM works alongside CAD—using CAD designs,
CAM uses numerical coding to run the machine that creates the product. A
CAD/CAM package allows companies to develop and save their own product designs,
and program machines to create the actual component.
CAM systems can maximize utilization of a full range of
production equipment, including high speed, 5-axis, multi-function and turning
machines, electrical discharge machining (EDM) and CMM inspection equipment.
CAM systems can aid in creating, verifying, and optimizing
NC programs for optimum machining productivity, as well as automate the
creation of shop documentation.
