About this event
If you work with parts, drawings, fixtures, inspection, or production handoffs, GD&T is one of those skills that quickly separates guesswork from precision. This virtual classroom is built to help you understand how geometric dimensioning and tolerancing communicates design intent clearly, reduces ambiguity, and supports better outcomes across engineering and manufacturing. About the Event This event is a fundamentals-focused virtual classroom on Geometric Dimensioning and Tolerancing (GD&T), designed for people working in and around advanced manufacturing and robotics. Rather than treating drawings as a collection of symbols to memorize, the session centers on how GD&T functions as a practical language for defining part requirements, allowable variation, and relationships between features. Expect a structured learning experience that starts with the core concepts and builds toward real-world interpretation. Whether you are new to GD&T or want to strengthen the basics you rely on in day-to-day work, this format is meant to help you develop working confidence, not just familiarity with terminology. Because this is a virtual classroom, the event is especially useful for professionals who want focused instruction without travel. You can learn from anywhere while still participating in a session designed to be clear, organized, and directly relevant to technical work. What to Expect You can expect a fundamentals-first walkthrough of the concepts that make GD&T useful in engineering and manufacturing environments. The session will likely move from the building blocks of the system toward more applied interpretation, so attendees leave with a framework they can use when reading or discussing technical drawings. Topics in a fundamentals course like this typically include: Why GD&T exists and how it improves communication over traditional dimensioning alone How tolerances affect function, fit, assembly, and manufacturability Datums and datum reference frames as the basis for defining and measuring part relationships Common geometric controls and what they are intended to communicate How to interpret feature relationships on engineering drawings with greater clarity How GD&T supports inspection and quality conversations across teams The learning experience is likely to be most useful when approached as both design communication and manufacturing problem-solving. That means the value is not only in recognizing symbols, but in understanding what those symbols mean for machining, assembly, inspection, and product performance. For people in robotics and advanced manufacturing, that practical lens matters. Tolerance decisions influence alignment, repeatability, motion, fit between components, and consistency across production. A solid grasp of GD&T helps you connect the drawing to what actually happens on the shop floor, during inspection, and in final assembly. Why Attend GD&T fundamentals are valuable because they reduce uncertainty. When teams interpret drawings differently, the result can be scrap, rework, delays, inspection disputes, and avoidable friction between design and production. Learning the fundamentals gives you a more reliable way to understand what a part must do and how that requirement should be communicated. This is especially important in fields like advanced manufacturing and robotics, where assemblies are often sensitive to variation and components must work together with precision. Better GD&T knowledge can help you ask sharper questions, spot possible issues earlier, and communicate more effectively with engineers, machinists, programmers, inspectors, suppliers, and quality teams. Attendees should come away with practical benefits such as: Stronger drawing interpretation skills A clearer understanding of design intent Better communication across design, manufacturing, and quality functions More confidence in tolerance-related discussions A foundation for applying GD&T in future technical work Even if you are not the person creating drawings, understanding GD&T can improve how you collaborate. It helps you evaluate what matters, what is critical to function, and where variation is acceptable. That perspective can improve decisions in quoting, planning, machining, inspection strategy, process improvement, and product development. Practical Details This is an online / virtual event, which makes it accessible whether you are attending from an office, lab, classroom, shop support role, or home workspace. Since the session is delivered in a virtual classroom format, plan for a setting where you can focus, follow technical explanations, and take notes as concepts build on one another. The event is scheduled for Monday, August 17, 2026 at 12:00 AM UTC. If you are joining from a different region, be sure to convert the start time into your local time zone in advance so you can plan your day accurately. A few useful ways to prepare: Set aside uninterrupted time so you can stay with the material from start to finish Bring questions from your own work if you regularly deal with prints, part requirements, or inspection issues Keep a notebook or digital notes ready for terms, definitions, and examples you want to revisit Join from a reliable internet connection for the smoothest experience If GD&T has ever felt overly abstract, inconsistent, or difficult to apply, this fundamentals session offers a strong place to start. It is a practical opportunity to build a clearer understanding of one of the most important communication systems in modern engineering and manufacturing.
Who should attend
This session is for people who want a stronger, more practical grasp of how technical drawings communicate part requirements and tolerances. - **You work in manufacturing, machining, quality, or inspection** and want to read GD&T with more confidence instead of relying on partial familiarity. - **You are an engineer or designer** who needs a better fundamentals-level understanding of how tolerances affect function, assembly, and manufacturability. - **You support robotics systems or precision assemblies** where alignment, fit, repeatability, and feature relationships matter. - **You collaborate across teams** and want to communicate more clearly with design, production, suppliers, or quality personnel when drawings and tolerances are involved. - **You are early in your career or transitioning into a technical role** and want a solid foundation you can build on before moving into more advanced applications. - **You have seen GD&T before but never felt fully comfortable using it** and want a structured virtual classroom setting to connect the symbols to real manufacturing meaning.
