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.

5. Before AutoCAD

6. ҉Michael Riddle
҉ 1979 - Interact CAD
҉ Language used – SPL
҉ Software runs on marine chip 9900

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).
• Height:

8. PROJECTION
It is the phenomena of projecting the image
of an object through light source.

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.
α=β=γ=120°αβ

15. Dimetric View
α=β≠γ
α=β=135°
γ =90°

16. TRIMETRIC VIEW
α≠β≠γ
α=120°

17. One Point Perspective View
All the line in the drawing converge at one specific point,
called vanishing point.
One Vanishing Point

18. Two Point Perspective View
 Two Vanishing Point

19. Vanishing Boundaries
Zero Point Perspective View
