1. What is GD&T? Geometric Dimensioning and Tolerancing (GD&T) is a standardized symbolic language used in engineering drawings and computer-generated 3D models to define the allowable variation in part geometry. It provides a precise method for specifying how parts must be manufactured and inspected, ensuring they meet functional requirements. GD&T
This article sums up all the specifications you need to consider when preparing a technical drawing for any CNC machining project and details the 10 steps to follow to get a flawless design. In the modern world of CNC machining, manufacturing typically starts with a 3D CAD model created using
In engineering and design, a datum is a reference point, line, or surface used to measure other dimensions. It’s crucial for ensuring consistency and accuracy in manufacturing and design. First, the process involves selecting a feature on a part that will serve as the primary reference. This should be a
General Assembly Drawings An assembly drawing (see Figure 1) represents the relative position and/or shape of a group of assembled parts. It also depicts the constituents of a parts list.A list of parts is often provided in a separate document, i.e. a parts list, but can be included within the
