Track revisions from revision 0 onward, record changes in the revision block, assign new issue numbers for affected parts, and reference alteration sheets.
Explore scale drawings with uniform ratios and original scales, and learn first angle and third angle projections, tolerances, surface finish, and unit indications in title blocks and drawings notes.
Discover how third angle projection represents objects with six two dimensional views on transparent planes, placed below and behind the observer, widely used in the United States and Australia.
Learn how form symbols define straightness and flatness tolerances, including two-dimensional zone and axis straightness, and how these controls apply to flat surfaces, cylindrical axes, and uniform paths across features.
Explain symbols for circle roundness and cylinder form, detailing how roundness and diameter dimensional tolerance define true shapes independent of datum features, with shafts, pins, bush fits, and cylindrical bores.
Explain position and true position in GD&T, the role of datum references, and how positional tolerances define allowable location variations for holes and features.
Master maximum material condition concepts where a feature of size contains the greatest material, and apply tolerances, bonus tolerances, and feature control frames to shafts and holes.
This Introduction to engineering drawings and blueprints course is aimed at those who have little or no previous experience of working with engineering drawings and who are required to read, understand and interpret them as part of their role. Working with engineering drawings involves understanding and analyzing, making decisions, and processing data. The Introduction to engineering drawings and blueprints based on practical application of print interpretation. It will give you a better understanding of the view representation, dimensions, tolerances, and symbols used on prints.
