does anyone send me pdf file to understand GD&T application?? | GrabCAD QuestionsOne of the most important is to capture the intention of the designer and all of the requirements associated with the newly designed product. The next benefit or purpose of the engineering drawing is to act as a communication tool. These handwritten notes became a source of error as organizations began scaling up or when those notes needed to be translated to other languages. This will allow you to understand the intent of the product designer, which will allow you to assess the conformance of a unit coming off of your production line. Additionally, it is not uncommon for designers to identify features that are CTQ Critical to Quality on an engineering drawing. The first tool in your engineering drawing toolbox is the drawing view. Drawing Views are simply the representation of your component from multiple perspectives Front, Side, Top, etc.

A datum feature is usually an important functional feature that needs to be controlled during measurement as well. The datum features on a drawing are denoted with a series of capital letters. These letters are in boxes and tied to the datum feature with a black triangle. This letter will also show up in any feature control frame that uses this datum feature as a reference. As stated before, datums can be located on points, axes,edges, and surfaces. Here is how different types of features are called out on engineering drawings. The symbol must be placed on or with one single extension line out of the datum surface.

Fischer - Now in its second printing. Changes in the structure, philosophy, expansion of scope, and the overall intent of the new revision are discussed. New terms, definitions, symbols, rules, feature types, tools, techniques, approaches, and changes made to each section of the standard are also discussed. Author's Note: This is a great book, beautifully laid out, with 2D and 3D full-color illustrations. Many of the concepts explained are accompanied by figure sequences which are constructed to explain each step of a process. The book contains multiple approaches and examples of Datum Feature Simulation sequences and gaging examples.
