Print Reading (915108)
Engineering drawings (often still called blueprints) are the means of communicating the necessary requirements of a product or assembly. While much of a drawing is devoted to the different visual views, there is a great deal of other information to understand. This one-day course covers the basic areas of interpreting mechanical drawings, from the details found in a title block to the meaning of different line types to a proper method for visualizing a part from the two-dimensional images. Participants will also learn how to interpret dimensions and tolerances, and review several sample drawings throughout the day.
