  26. Projecting a Third View (1)

  27. Projecting a Third View (2)

  28. Projecting a Third View (3)

  29. Projecting a Third View (4)

  30. Projecting a Third View (5)

  31. Aligning Views

  32. Alignment of Views The standard view set forms an L 32

  33. Alternative Positions of Views Minimize wasted space

  34. Parallel Edges

  35. Angles Angle will only print correctly, if the view is on the plane of that angle

  36. Interpreting Views • One method of interpreting sketches is to reverse the mental process used in projecting them • Each view provides certain definite information about the shape of the object and all are necessary to visualize it completely

  37. First- and Third-Angle Projection • There are two main systems used for projecting and unfolding the views: • Third-angle projection which is used in the United States, Canada and some other countries • First-angle projection which is primarily used in Europe and Asia • You should understand both methods We will only use 3rd angle

  38. First-angle Projection

  39. Create your own drawing

  40. Make The Drawing

  41. Turn it into a drawing

  42. Choose the sheet size A is regular 8.5”x11”

  43. View Pallete

  44. Toolbar

  45. Open The 3 Standard Views • Choose ‘Standard 3 View’ under ‘View Layout’ • Choose the part you want to draw, and click the check

  46. Right click the sheet, and choose ‘properties’

  47. Change doc properties • Change scale • Change projection type

  48. Change the drawing view • Click on the 1st view

  49. Choose a different view • Click on the view you prefer
