2. Plane of Projection (Paper)
Projection Theory- Represent 3D objects on 2D media to give a clear understanding what the part looks like
2 Variables
Line of Sight (LOS)
Plane of Projection (Paper)

3. Plane of Projection- Flat plane where is projected
Line of Sight (LOS)- imaginary ray of light between an observers eye and an object
Plane of Projection- Flat plane where is projected
(always perpendicular from LOS)
90°
Any > 3D

4. Different distances change what it will look like
Perspective- all lines originate from finite distance of sight at a single point
Different distances change what it will look like
How we see it!
Real Life

5. Parallel- all lines of sight are parallel (part positioned parallel to picture plane at infinite distance)
Imaginary
Not Real Life

6. Planes of Projection (Dimension they provide)
Frontal (_________ & ________)
Horizontal (__________ & ___________)
Profile (_________ & __________)
Solid Works calls these planes what?
What is the minimum # of views to get all 3 dimension of a part?

7. What are some examples of each?
Types of Drawings
One View
Two View
Three View
What are some examples of each?

8. Understanding Exercise
Identify which plane of projection the view asked for is projected onto
Identify which of the 4 views is the correctly projected according to the arrow or view direction

9. Multi-View Projection vs. Perspective
No distorted surfaces or dimensions (Scalable)
Aligned views fill in gaps of confusion
What is not clear with the isometric alone?

10. 6 Principle Views 3 views conventionally used:
____________ , __________, and _______
What do they call it in Solid Works?

11. Rules to select Views: Most Descriptive views Natural Orientation
Minimum # of views
No dimensions to hidden lines

12. Number of Views and Which is Front View?

14. First Angle Projection Third Angle Projection
VS.
Third Angle Projection
3 names you might hear?

21. Fillets (Interior Corner) Rounds (Exterior Corner) on Planes
vs.
Rounds (Exterior Corner) on Planes
What is difference between a fillet/ round & a chamfer?
2 ways to define chamfer
_____ x ______& ______ x ______

22. Runout- corners where fillets intersect cylinders

23. True Length/Foreshortened/ Point view

24. True Size & Shape/Foreshortened / Edge
Planes of a part
Normal
Inclined
Oblique
What do we have to create to show true shape and size of an inclined or oblique plane?
Comparison Chart

25. How do I really locate where to drill the hole?
Why do we care?
How do I really locate where to drill the hole?

26. Understanding Exercise
Identify what line or plane type is represented in the example below.

27. Partial Views- Show only necessary information to convey design intent
Use Break or Center line
Noted: Some hidden lines removed for clarity

28. Why is scale not noted in other views?
Removed Views
AKA Detailed Views
Why is scale not noted in other views?

29. Homework
Determine Front View
Minimum# of views
Tangencies removed
All needed dimensions
