Geometric Tolerancing and Dimensioning Basics (GD&T Basics)

This one-day course is an overview of the GD&T concepts in controls necessary for proper engineering drawing reading and creation using the GD&T approach. The course will cover typical issues that can occur when applying a traditional coordinate system and how Geometric Tolerance can overcome them. You will be introduced to the symbols, terminology and the rules for GD&T based on ASME Y14.5:2018.

Enrollment Options

Select an existing open enrollment session, or contact us for additional training options.

Length

1 Day

*For private workshops for your organization, a one (1) day add-on Application Coaching Workshop service is available based on a customization of additional GD&T exercises.

Prerequisites

Live Virtual Only:

Required

Equipment Needed (Live Virtual Only):

Provide a Basic Understanding of GD&T
Define the key terms of GD&T and how they affect the interpretation of drawings.
Define and understand the proper symbols, modifiers, and feature control frame format.
Define the GD&T characteristics.
Demonstrate an understanding of the GD&T characteristics by:
Sketching the characteristics
Sketching tolerance zone
Understanding the impact of modifiers on the tolerance zone

This Live Virtual Workshop is recommended for engineers and technicians that need to read or create engineering drawing using the GD&T approach. Typically, this includes product engineers and designers, tooling and maintenance engineers and technicians, quality, inspection, manufacturing, procurement, and purchasing professionals, as well laboratory technicians who must perform gauging to layout inspections.

Combining the best of online and traditional face-to-face learning, Live Virtual Workshops use web-based teleconferencing technologies to bring your team together with our experienced instructors in an interactive learning environment. We have always believed interactivity, application, and group discussion are critical parts of an effective and sustainable learning experience. To ensure that these values hold true, and every participant can build the same caliber of knowledge, each workshop includes the following Live Virtual functionality and features:

Trainers & Moderator support: For every session, both trainers and moderators (or on-site staff) will be present and accessible to ensure optimal interaction for each participant, upholding the intimacy of our training model. Participants may interject and raise hands at any time, speak directly to trainers, moderators, and other participants, and share feedback in real-time.
Exercises & Break-out Rooms: Throughout the session, participants will be assigned to teams and split into breakouts to privately complete group activities and discussions, then returning to the larger group to present. There will also be quizzes (or polls) throughout to measure knowledge retention during the units.
Digital Learning Package or Shipped Materials: Depending on the course, participants may receive a hardcopy of the Participant Training Book and/or receive a digital learning package complete with training handouts, case studies, digital workbooks, and a virtual platform user-guide.
Technical Support & Resources:  If this is your first-time training with Plexus International or in a Live Virtual Workshop environment, we have prepared resources and user guides to help you navigate any conferencing technology and will support your teams hands-on in case you need any extra assistance. Join any session 30 minutes early and a moderator or support team member will guide you in experiencing the key functionalities and features used in our training sessions.

In this introductory course, participants will gain knowledge on GD&T foundations for reading, designing, and inspecting parts based on GD&T drawings. This is also a great refresher course on GD&T for product, manufacturing, and quality engineers and the APQP multidisciplinary team members in general. The training includes high-quality PowerPoint graphics and use of wood and plastic models to demonstrate physical meaning of each Geometric Tolerance.
