GD&T Techniques

GD&T is an indication system for regulating form. By using GD&T drawing techniques, you can improve the efficiency of processing and inspecting mating parts such as shafts and bores. You can also accurately indicate specifications to maintain a certain thickness for a part that needs strength.
Additionally, heights of protruded screws, as well as shapes of rubber or resin products or other soft parts, can be specified.
This section introduces the techniques for indicating specifications for extraordinary circumstances and materials.
