1. AutoCAD: LEARNING OBJECTIVES

What is AutoCAD?
AutoCAD is a computer-aided design (CAD) program used for 2-D and 3-D design and
drafting. AutoCAD is developed and marketed by Autodesk Inc.
AutoCAD allows you to visually design and explore your
conceptual design ideas, modify your designs using 3D free-
form design tools, generate intelligent model documentation,
transform your designs into 3D renderings, and turn them into
cinematic-quality animated presentations.
AutoCAD is the most popular drafting software used by
architects & engineers (Civil, Electrical & Mechanical &
manufacturing). AutoCAD is primarily a drafting software with
3D modelling functionalities.

Learning Objectives in 1E9


 To familiarise with the AutoCAD workspace and user interface
 Using basic drawing, editing, and viewing tools.
 Organizing drawing objects on layers.
 Inserting reusable symbols (blocks).
 Preparing a layout to be plotted.
 Adding text, hatching, and dimensions.
 Creating multi-view projections using AutoCAD
 Creating isometric views using AutoCAD
 Basic 3D rendering using AutoCAD
 Development of basic floorplan using AutoCAD

2. AutoCAD DESIGNS IN LABS

The three labs on AutoCAD will focus on:


1 Learning the basics such as drawing, modifying, using layers etc. in first lab
2 Learning to draw an architectural floorplan using AutoCAD in second lab
3 Learning to develop 3D models of simple machine tools

Lab Schedule
No changes or swaps are possible to this schedule. You may bring your own laptop and
work on the freely downloadable AutoCAD software.
3. ACCESSING AutoCAD

AutoCAD 2015 can be used in Civil Engineering CAD lab. The labs are open for students
between 9am-5pm and can be used for accessing AutoCAD.
Apart from this, AutoCAD 2019 is available on the Public Access Computer rooms in the
Hamilton area, Ham1, 3 and 4.
For home use or personal use, an educational license of AutoCAD 2017 or later versions
can be downloaded for free from

4. BASICS OF AUTOCAD

Welcome Screen
The welcome screen provides two space options: Learn & Create. Learn
shows help files, videos and any new additional features.
The ‘Getting Started’ videos on the welcome screen on the Learn space is
really useful to understand the basics of 2D drafting.

Create tab is for creating new drawing. Start with start drawing for this module.
Workspace
1. Quick Access Toolbar: New, Open, Save, Save All, Plot, Undo and Redo.  
2. Ribbon Tabs: Below QAT you will find all Ribbon Tabs available in this WorkSpace. Different Ribbon tabs offers different Ribbon panels
depending on your work.
3. Search: You can search any commands or information by entering any Keywords or Phrase.
4. External Links: Facebook, twitter etc.
5. Help: This tab may be visible by clicking the double-arrow at the end of external link bar.
6. Title Bar: Here you will see your Drawing file name which is open currently.
7. Application Menu Button (AutoCAD Logo): This AutoCAD application menu offers different options along with Default QAT options.
8. Ribbons: The main Toolbar area where you will find all Tabs in panel format arranged as per their use. Ribbon consists of panels such as
draw, modify, layers, annotation etc.
9. File Tabs: New drawing files can be added by pressing [+] icon.
10. Viewport Controls: This is on Screen View port controls form where you can change AutoCAD views and Visual Styles.        
11. View Cube: Through ViewCube a Drawing can be seen from different directions and angles. With ViewCube, you can switch between
standard and isometric views.
12. WCS: World Coordinate System
13. Navigation Bar: The Navigation Bar contains navigation tools such as Steering wheel, Pan, Zoom, Orbit, and ShowMotion.
14. Drawing Area/ Graphics Area: This is the main area of Model where new Drawings are created. This is an infinite space area.
15. Command Line: For typing AutoCAD commands from keyboard
16. Model and Layout Tabs:
 Status Bars:
17.  Drawing Settings: This is application status bar which consist of different settings such as grid on, snap on etc.
18. Additional Settings: This contains annotation and some additional settings, such as scale, workspace switch etc.
19. Drawing Coordinates: This shows current location of cursor in Drawing coordinates.
20. Coordinates
There are 3 workspaces available in AutoCAD: Drafting & Annotation, 3D Basics, and 3D Modelling. By default, the Drafting & Annotation
workspace is activated. 2D drawings can be created in this workspace. You can also activate other workspaces by using the Workspace drop-
down menu or Workspace switching menu.
You may use the video tutorial Tour the User Interface from the software.
2D Drawing in AutoCAD
Please refer to the pdf document ACAD Quick Ref for detailed steps on how to create a drawing in AutoCAD. You may also use the
video tutorials available at the learn section of AutoCAD in this purpose.
The following are the key panel and functionalities in AutoCAD which are needed for drafting.

 Draw
 Modify
 Layer
 Annotation & Dimensioning
