About this event
If you work with manufactured parts, drawings, inspection, or product development, GD&T is not optional background knowledge. It is the shared language that helps design intent survive the trip from CAD model to shop floor to final inspection, and this online session is built to make that language clearer, more usable, and easier to apply with confidence. About the Event This virtual event is an introduction to Geometric Dimensioning & Tolerancing (GD&T) with reference to Y14.5, designed for people working in advanced manufacturing, robotics, and related technical environments. Whether you have seen GD&T on drawings but never felt fully comfortable reading it, or you want a stronger foundation before moving into more advanced applications, this session gives you a structured place to start. GD&T can feel intimidating because it combines symbols, rules, datums, feature control frames, and inspection logic into a compact notation system. But the goal is practical, not theoretical: to communicate part requirements clearly enough that designers, machinists, quality teams, suppliers, and engineers can make consistent decisions. This event focuses on that practical purpose so attendees can connect the standard to real engineering work. Because the event is online, it is especially useful for distributed teams, remote professionals, and anyone who wants to build technical fluency without travel. You can attend from wherever you work and focus on understanding the logic behind GD&T in a format that supports concentrated learning. What to Expect Expect a guided introduction to the core ideas behind GD&T rather than a rushed symbol dump. The session is centered on helping attendees understand how GD&T communicates design intent, how it differs from traditional coordinate dimensioning, and why it matters so much when parts need to function, assemble, and inspect reliably. Topics are likely to include foundational concepts such as: What GD&T is and why it exists How Y14.5 supports consistent drawing interpretation Basic symbol literacy so drawings feel less opaque Datums and datum reference frames as the backbone of functional measurement Feature control frames and how to read them The relationship between tolerance, fit, function, and manufacturability How design, production, and inspection teams use the same notation differently You should also expect the session to connect concepts to practical manufacturing and engineering workflows. In advanced manufacturing and robotics, small interpretation errors can lead to scrap, rework, assembly issues, supplier confusion, or avoidable inspection disputes. A good introduction to GD&T helps reduce those problems by making the intent behind a print more explicit. As a virtual event, the format is well suited to focused instruction and note-taking. It is a strong opportunity to build vocabulary, sharpen interpretation skills, and identify the areas of GD&T you may want to study more deeply afterward. Why Attend The value of learning GD&T is not limited to drafting specialists. If you touch product design, precision manufacturing, process planning, robotics hardware, quality systems, metrology, or technical sourcing, a stronger command of GD&T helps you ask better questions and make better decisions. Attending this event can help you: Read technical drawings with more confidence Understand how functional requirements are translated into tolerances Communicate more clearly with machinists, inspectors, suppliers, and engineers Spot ambiguity earlier, before it becomes a production or quality problem Build a stronger foundation for future work in design for manufacturing, inspection planning, and tolerance analysis For professionals in robotics, this matters even more because assemblies often depend on precise relationships between features, interfaces, and motion-critical parts. For professionals in advanced manufacturing, GD&T knowledge supports tighter feedback loops between engineering intent and real-world production outcomes. Even if you are early in your GD&T journey, this introduction can save time later. A solid foundation makes advanced topics easier to learn, helps you avoid common misunderstandings, and gives you a more useful framework for interpreting prints, discussing tolerances, and evaluating what a part actually needs to do. Practical Details This is an online / virtual event, which makes it accessible regardless of geography and easy to fit into a technical learning schedule. You do not need to travel, and the remote format makes it especially practical for working professionals, distributed teams, and attendees joining from manufacturing, engineering, or lab environments. The event takes place on Monday, September 7 at 12:00 AM UTC. Because the time is listed in UTC, it is worth converting it in advance to your local time zone so you can plan accordingly and arrive ready to focus. A few simple ways to get more out of the session: Join from a setup where you can view diagrams or slides clearly Keep a notebook or digital document ready for terminology and examples If you already work from drawings, bring your real-world questions with you Be ready to connect the concepts to your own design, manufacturing, or inspection context If GD&T has felt like something you should already know, this event offers a clear entry point. It is a practical, accessible way to build confidence in one of the most important technical communication systems used across modern manufacturing and robotics.
Who should attend
This is for you if you want a clearer, more practical grasp of how GD&T works in real engineering and manufacturing settings. - You are a **mechanical engineer, manufacturing engineer, or product engineer** who needs to read, create, or review drawings with more confidence. - You work in **advanced manufacturing or robotics** and want to better understand how tolerance decisions affect assembly, performance, and inspection. - You are part of a **quality, metrology, or inspection** team and want stronger fluency in the logic behind datums, feature control frames, and functional requirements. - You are a **machinist, programmer, technician, or process planner** who regularly works from prints and wants fewer interpretation gaps between design intent and production reality. - You collaborate with suppliers or cross-functional teams and need a more consistent technical language for discussing part requirements. - You are newer to GD&T, or you have learned it informally over time, and you want a solid introduction tied to the **Y14.5** framework rather than scattered pieces of knowledge.
