Since the late 1940s, geometric dimensioning and tolerancing (GDT) has become an essential component of complete part definition. It affects most areas of product realization including design, tooling, production and inspection. The ASME Y14.5-2009 Dimensioning and Tolerancing and ASME Y14.41-2012 Digital Product Definition Data Practices standards show how to apply GDT to 2D part views and 3D models respectively. While Siemens CAD programs refer to the 3D dimension application as product and manufacturing information (PMI), it is commonly known as model-based definition (MBD). This presentation will show how to use Solid Edge to apply GDT symbols to 2D part views and 3D models.
