Model-Based Definition
GD&T and tolerance analysis are part of a broader model-based definition journey. MBD is an approach to creating 3D models that effectively contain all product data needed to define a product.
GD&T is the process of annotating designs, using a symbolic language to define the allowable geometry dimensions. Tolerance analysis allows engineers to understand how stack-up of variation impacts the design quality and manufacturability.

Evaluate the impact of dimensioning on product designs before either prototyping or manufacturing.
Model-based product development is the process of using the native CAD model throughout the entire product development cycle. Beginning with concept development, including industrial design, ranging all the way through detailed design, simulation, tooling development, manufacturing process development and service instructions, the native CAD model drives the digital thread through the entire product development lifecycle.
