Dustin Smith, metrology and software training lead at Assurance Technologies Inc., addresses common questions from his GD&T course. He emphasizes the need for everyone—from sales to engineering, production, and quality—to have a basic understanding of GD&T.

The use of advanced 3D scanning tools is revolutionizing quality control, design, and manufacturing, particularly with the adoption of digital standards and 3D printing. However, this shift presents challenges in maintaining consistent standards globally and across different regulations.

GD&T is a language for precise communication of complex geometric requirements for parts and assemblies. It specifies tolerances for exact requirements, ensuring understanding among team members.

Electronics manufacturing needs advanced metrology to create high-reliability components. Technology is advancing to combine metrology and microscopy for better defect identification.

Model-Based Definition (MBD) offers a modernized approach to implementing GD&T into electric motor production using 3D models instead of traditional 2D drawings.

The vast digital loop across key domains that CT analysis can play a role in allows it to contribute critical insights back to design from embedded simulation and virtual metrology testing, as well as all phases of process examination and related refinements.

The National Institute for Metalworking Skills (NIMS) announced that it has developed a new methodology to learn, retain, and transfer knowledge for Geometric Tolerancing & Dimensioning (GDT) across an organization.

Experts agree that, among other tools, digital twins are emerging as stars of smart factories. These are 3D duplicates of parts, products, and buildings.

For most students, measurement and GD&T is a new subject for them. I get the opportunity to review the basic concepts each year. Let's review some of the elements of geometric dimensioning and tolerancing.
