Abstract
Automatic Computer Aided Design (AutoCAD 2D) engineering drawing is an important
component in BFPD courses. This software is commonly practiced by students for product
design process as part of the project development. However, there is a lack of quality in 2D
engineering drawing that affects the students’ prototype making process and project progression.
This paper intends to identify the problems that weakened the students' performances of the
AutoCAD 2D engineering drawings. Data were collected from the students’ examinations,
assignments and independent projects. Semi structured interviews were also conducted with the
students.

Introduction:
AutoCAD was derived from a program that began in 1977, and then released in
1979called Interact CAD, also referred to in early Autodesk documents as Micro CAD, which was
written prior to Autodesk's (then Marin chip Software Partners) formation by Autodesk cofounder
Michael Riddle.
The first version by Autodesk was demonstrated at the 1982 Comdex and released that December.
AutoCAD supported CP/M-80 computers. As Autodesk's flagship product, by March 1986
AutoCAD had become the most ubiquitous CAD program worldwide. The 2020 release marked
the 34th major release of AutoCAD for Windows. The 2019 release marked the ninth consecutive
year of AutoCAD for Mac. The native file format of AutoCAD is .dwg. This and, to a lesser extent,
its interchange file format DXF, have become de facto, if proprietary, standards for CAD
data interoperability, particularly for 2D drawing exchange.[citation needed] AutoCAD has
included support for .def., a format developed and promoted by Autodesk, for publishing CAD
data.
Advantages of AutoCAD
The following are the top 12 advantages:
Accurate and Reduces Errors – The principle on which AutoCAD works is a dynamic
engineering model. This model blends design and production drafting together which
allows the changes to be made to any part of the design at any point in time in the entire
project. This results in error reduction and fewer chances of mistakes. Furthermore, the
designs which are made digitally always have room for enhancements and improvement.
Save Time & Money – With a specific and user-friendly interface and workflow,
AutoCAD works speedily which saves the time of the designer. AutoCAD supports
documentation tools that not only increase productivity but also help the designers and
architects to streamline the designs and documentation workflows. It also provides
solutions to implement modifications in the projects, thus reducing the time taken. It is an
efficient program that undertakes the work process of the designer and helps in saving time
and money and reducing errors.

Easier Data Transfer – Using AutoCAD in Architect Designing has made it easier to share
files with multiple people simultaneously. It is not easy to work on heavy files and then
share them without any data loss. But, this software has made it easy to upload the designed
data on the internet and sharing it with numerous other designers.
Controllable in nature – This advantage of AutoCAD supports the scanning feature for the
data. This technique helps in measuring the quantity of the materials used. It also helps in
calculating the exact cost of the products. Eventually, it helps in managing production and
post-production processes.
Database for manufacturing – AutoCAD allows in creating manufacturing data such as
materials required for components, dimensions, and shape of the models, product, and
component drawings. This helps in creating and managing a wide database which is an
important part of the production process.
Easier Import/ Export of files – AutoCAD Inventor supports file import and export
features. AutoCAD allows the users to import models from Inventor and it also manages
to do it quite easily and speedily. AutoCAD also supports various other tools and features
that boost the productivity of the program. Some of them being; PDF support, compatible
with Autodesk 360, social media sharing, AutoCAD WS, DWG Convert, and many more.
AutoCAD also supports PRESSPULL operations which allows the users to create surfaces,
solids, and offset curves with much ease. These meshes are dynamic in nature and can
easily be manipulated. The designers can easily develop physical 3D Frameworks of their
designs with the 3D printing capabilities of AutoCAD.
Apply Point Clouds – Point Cloud is a large collection of points resulted from 3D laser
scanners to create a 3D presentation of default structures. The users can join these point
clouds to use as a starting point for their designs.
Layering feature- This feature allows the user to hide or show specific details of a
complicated complex group of drawings for clear understanding.
Calculation- The user can calculate Mass, Area, volume, Center of Gravity in no time. This
program has an Auto- Dimensioning feature that helps in designing easy and accurate
sketches. The users can also generate 2D drawings from 3D models.
Commands like Fill, Hatch, Section lines, chamfer, and fillet makes AutoCAD one-stop
solutions to many designers as these operations are impossible in manual drafting.

6. 5
Image tracing feature- This helps in a digital tracing of conventional diagrams and drawing.
PDF import enhancements- It also has an SHF text recognition tool that converts the
geometries imported from PDF text to Text objects which can be edited more conveniently.
Basic AutoCAD Function Keys:
The function keys of the keyboard can be used to control several AutoCAD settings, let us look
at a few examples below.
1. F1
This function key opens the AutoCAD Help window. It allows the user to take help online if he/she
is facing any functional issue in this software. If a user is working offline than by pressing this key
all the functionalities of this software will be opened in PDF format.
2. F2
This key opens a pop-up screen showing the command line on the bottom. This command is useful
to the user who feels difficulty in seeing the command window on the bottom of the screen.
3. F3
This command automatically activates the O snap feature of AutoCAD. O Snap feature of this
software helps to draw your drawing accurately. This will allow you to snap at the specific location
of your object while you are picking any point. For example, a user can accurately pick up two
points of the line, the center of a circle, etc. If you again press this key software will come out from
this command.
4. F4

7. 6
This key will open the O snap feature while working in 3 dimensional. This command will allow
us to accurately pinpoint on the particular position of a body.
5. F5
ISOPLANE is the plane with an angle of 30 degrees from horizontal. By using this shortcut key,
we can create any drawing in ISOPLANE.
ISOPLANE provides the following modes when working with a 2D isometric view of 3D models:
Ortho Direction
Snap Orientation
Grid Orientation
Polar Tracking Angles
The orientation of Isometric circles
This command will affect the cursor movement only when the snap style is set as isometric. If the
snap style is set as Isometric, Ortho mode will use appropriate axis pair from 30, 90, and 150
degrees.
By pressing this command again, we can alter between three ISO planes that are top, right and
left.
6. F6
This function key turns dynamic UCS on or off. UCS is a user coordinate system that a user can
define according to his requirement. Before 2007 when this command is not available while

8. 7
working, 3D user has to create a new coordinate system every time he/she changes his drawing
view. This command is only used when working on 3-dimensional objects.
7. F7
This function key will display grids in your AutoCAD drawing. The grid system allows the user
to reorient him and after that, he can focus on his design. He/She can make the grid visibility off
by pressing this key again. By changing isometric planes the user changes his viewpoint when
working in AutoCAD’s Isometric mode. It allows him/her to move viewpoint relative to the 2D
isometric object.
8. F8
This command will turn ORTHO mode on or off. This is one of the most useful keys in AutoCAD.
This mode is used when the user has to specify an angle or distance using two points using a
pointing device. By using this mode cursor
movement will become constrained in the
horizontal or vertical direction relative to the
user coordinate system.
9. F9
This key will make a snap grid on or off. Grids are the rectangular pattern of dot-like structure in
AutoCAD that covers the entire XY plane of the user coordinate system. Using Grid in AutoCAD
is like using the grid paper under your drawing. This will allow the user to align objects and
visualize distances between them. By using this key, you can easily snap to a rectangular grid and
create your drawing more easily and efficiently.

9. 8
10. F10
This function key will allow the user to use the polar tracking option of AutoCAD software. Polar
Snapping command will restrict your cursor movement only to specified increments along with
the polar angles. Polar tracking will display temporary alignment paths defined by those polar
angles you had earlier specified. It also provides additional alignment in up and down directions.
This command is useful while working on objects having more than one different orientation when
one part of the object is rotated 45 degrees in relation to another part. While working with this
command ORTHO command will automatically be shut off.
11. F11
This key will allow using Object Snap Tracking Command. Object Snap allows the user to snap
onto the specific object location when you are picking a point. This is used with other commands
to draw your design more accurately. It is so much important to command that without it you will
never able to draw accurately. Some designers use object Snap Tracking command always ON and
never turn it OFF.
12. F12
This command will allow us to use the Dynamic Input command of this software. Dynamic Input
provides user cursor input, dimension input, and dynamic prompts. When you right-click after
selecting dynamic input you can select any input according to your requirement. By using this you
can provide dimension inputs near your cursor instead of specifying it on the command line.
Auto CAD shortcut Keys:
To some that have abstained from utilizing keyboard-entered orders
out-and-out this may appear to be an overwhelming undertaking. Which means they will be more
significant than any other time in recent memory, and in particular tweaked to your AutoCAD
shortcut keys requirements.
By utilizing keyboard shortcut keys genuine efficiencies can be made to your work process,
regardless of on the off chance that you are now beyond words keyboard client or someone who
normally floats towards the utilization of AutoCAD’s strips and toolbars. The table has a list of

10. 9
some commonly used AutoCAD shortcut keys 2d and 3d that work with your computers and
software. It is highly recommended that all users should use these keys and try to remember them.

11. 10
Conclusion:
The student version of AutoCAD is functionally identical to the full commercial
version, with one exception. Learning the AutoCAD Shortcuts Keys can make your work go faster.
You can use the default keyboard shortcuts and create your own.
You can learn and easily use the AutoCAD shortcut keys that AutoCAD 2D and 3D commands
using the software easily. Most of the Civil Engineering and Mechanical Engineering students,
Draftsman and engineers were using almost so most of them are using the Mouse only. So better
avoid Mouse using and quick command that as 2D and 3D Commands as in an easy way
