2. What is AutoCAD ?
• AutoCAD is a computer-aided design (CAD)
program used for 2-D and 3-D design and
drafting.
• It is used for creating blueprints for
Buildings
Bridges
Computer chips
Machine parts
3. Advantages Of AutoCAD
Over Manual Drafting
Easy to draw
Less time consumption
Accuracy and precision
Quick access
Easier modification
Good appearance in output
Easy storage, easy sharing
Less prone to error
4. Using AutoCAD you can Design with confidence.
AutoCAD is having a Intelligent tools which help simplify
your work, and innovative features improve your workflow.

History Of AutoCAD
7. AutoCAD’s Applications:
• AutoCAD was initially created for
mechanical engineers, but very
quickly extended to encompass a range
of fields.
• One example of how AutoCAD has
successfully helped a project is the
construction of the “SHANGHAI TOWER”
(Construction started: 29 November
2008, Completed:6 September 2014,
Inaugurated:18 February 2015).

12. Different Types of Views
VIEWS
Parallel Views
•Orthographic View
•Isometric View
•Dimetric View
•Trimetric View
Perspective View
•One Point
•Two Point
•Three Point
•Zero Point
13. Orthographic View
It is the two dimensional views of three
dimensional objects.
It uses two axis
14. Isometric View
It visually represent three dimensional objects in two
dimensions in drawings.

IN 1982 they launched AutoCAD at COMDEX TRADE show in Las Vegas as the first CAD program in the world to run on PC.
Take a minute and imagine you are shopping for a chair to go in your living room. You find the perfect one, but it is way too expensive. Fortunately, you have a cousin that builds furniture. Maybe he can build the chair for you! Describing the chair over the phone was more than a challenge. Your cousin suggests you send him pictures of the chair from multiple angles, along with the measurements.
This experience illustrates the process that a furniture designer must go through in order for the manufacturer to create the chair as intended. Three-dimensional drawings can be used to show the overall concept and design, but they are often not clear or detailed enough. Orthographic drawings can help to overcome those challenges.
