1. Career & Technical Education Sketching Explain and demonstrate basic sketching skills and techniques.

2. Career & Technical Education Sketching Concepts Explain the concepts related to sketching.

3. Purpose of a Sketch Quickly & easily get an idea on paper  Design sketches  Freehand technical sketches  Technical illustrations

4. Freehand Technical Sketch

5. Design Sketch

6. Technical Illustration

7. Sketching Materials Paper Pencil  Soft lead Optional  Eraser  Grid Paper

8. Sketching Technique Proportion Clarity Sketching Aids

9. Sketching Lines Vertical lines  Top to bottom Long straight lines  Series of short straight lines

10. Sketching Circles & Arcs Begin by lightly constructing a square

11. Sketching Angles Begin with 90 ° angle 60 ° 30 ° 45 ° Subdivide onceSubdivide twice

12. Sketching Assignment Sketch 6 circles as shown on PPT Sketch 4 cubes Turn into me for a grade when finished

13. Career & Technical Education Sketching Explain the concepts and principles underlying isometric, oblique and multiview sketching.

14. Sketching Types of Sketches  Single-view  Multi-view  Pictorials

15. Single-view Sketching Technical purposes Front view  Most descriptive features

16. Steps for Single-view Sketching Object Step 2 Step 1 Step 3Step 4

17. Multi-view Sketching Technical sketch  Front view  Top view  Side view

18. Multi-view Sketch TOP VIEW R. SIDE VIEW FRONT VIEW

19. Single-view/Multiview Sketch Assignment Sketch a multiview as shown on PPT of the object I will display for you – I will pass the object around as needed

20. Pictorial Sketches Quickly communicate an idea Three dimensions in one view  Width  Height  Depth

21. Pictorial Sketches Three (3) types  Isometric  Oblique  Perspective

22. Isometric Sketch WIDTH DEPTH HEIGHT

23. Isometric Sketching Three equally spaced axes of 120 °

24. Isometric Sketching Receding lines  Typically 30° off horizontal

25. Isometric Sketching Circular shapes appear as ellipses

26. Isometric Ellipses Correct ellipse orientation

27. Isometric Sketching Non-Isometric lines  Locate endpoints and connect

28. Isometric Sketching Assignment Draw a simple isometric sketch of the same object used for the last multiview assignment

29. Oblique Sketch WIDTH DEPTH HEIGHT

30. Oblique Sketching Front view is drawn true shape and size

31. Oblique Sketching Receding edges are usually drawn at an angle of 30°, 45°, or 60°

32. Oblique Sketching Circles and curves drawn on frontal plane will appear true shape and size

33. Oblique Sketching Assignment Now draw an Oblique sketch of the same object

34. Perspective Sketches 2-Point Perspective1-Point Perspective

35. Perspective Sketches Objects appear as the eye would see them Most realistic type of pictorial sketch Most difficult pictorial sketch to draw

36. Perspective Sketching Assignment Now draw a one point perspective of the object
