GD&T Basics

GD&T Basics is a restaurant in Greenville, SC. The business is listed at a Greenville, SC address, and operates from 1708-C Augusta St. Suite 225 in Greenville, SC 29605.

GD&T Basics provides Geometric Dimensioning and Tolerancing training that helps engineering and manufacturing teams apply the ASME Y14.5 standard to real production work. The company was founded by Tom Geiss, who originally built a website to teach GD&T basics to colleagues in the automotive industry; demand from other companies led him to expand into formal training. Its first online course, GD&T Fundamentals, launched in January 2015 and drew more than 125 enrollees in its first two weeks. The catalog has since grown to include Advanced GD&T (2018), Print Reading and Tolerances (2019), and GD&T Inspection (2024). Training is delivered through self-paced online courses, on-site company classes, and public seminars, with group rates and bundle discounts available.

Instruction is led by ASME Certified instructors who teach from real-world engineering experience rather than theory alone. Courses cover practical print reading, a fundamentals framework for applying GD&T on the shop floor, advanced symbol and callout usage, and inspection practices including CMM and manual reporting methods. The company also offers customized consulting, where certified instructors review a client's prints, build inspection plans, analyze tolerance stacks, and help resolve supplier and customer disputes. Group training options include progress tracking through an online learning platform, direct instructor access through question hotlines, and LMS integration for groups of 50 or more.

To date, GD&T Basics has trained more than 50,000 engineers, machinists, quality technicians, and industrial professionals at hundreds of companies. Corporate accounts and individual learners can request quotes or enrollment information through the company's contact channels.
