GD&T Training Online: The Excedify Certification Pathway
Excedify’s online GD&T training program helps mechanical engineers, design engineers, and quality teams use GD&T correctly. It helps parts work as intended the first time.
This practical GD&T training teaches you to interpret engineering drawings, apply tolerances, and communicate design intent across teams.
The Excedify Advantage
Excedify is more than a typical GD&T course. It is a complete GD&T certification training program built around how engineers actually work.
Structured Learning
The program follows a clear sequence.
You begin with engineering drawing fundamentals.
Next, you learn GD&T fundamentals.
Then you move to advanced GD&T standards.
Finally, you learn tolerance stack-up analysis.
Each step builds on the previous one, so engineers logically learn GD&T.
Real Engineering Examples
You work with real engineering drawings and design drafting scenarios.
You interpret engineering drawings, apply tolerances, and analyze how variation affects assemblies. This approach helps engineers understand design intent and how tolerances affect manufacturing and quality control.
Visual Learning
GD&T concepts can be difficult to visualize. Excedify solves this with high-quality animations and diagrams.
You clearly see:
- How datum references control parts
- How feature control frames define tolerances
- How variation accumulates in assemblies
This visual approach makes learning GD&T faster and easier.
Built Around Industry Standards
The training follows major GD&T standards used in engineering.
The courses cover:
- ASME Y14.5 standard
- ASME GD&T principles
- ISO GPS industry standards
This ensures engineers can apply GD&T correctly across global supply chains.
Designed for Engineering Teams
Engineering managers can train entire teams with one GD&T training course.
Managers can:
- assign modules
- track progress
- standardize GD&T practices across teams
This makes the program ideal for organizations implementing geometric dimensioning and tolerancing training at scale.
Practical and Affordable
Many GD&T courses focus only on theory.
Excedify focuses on real-world engineering design problems while keeping pricing accessible.
Companies gain measurable ROI by improving communication between design, manufacturing, and inspection teams.
The four levels of the program
The program consists of four progressive courses.
Each course focuses on a specific skill engineers need when applying GD&T.
Level 1: Technical Drawing
Before engineers can learn GD&T, they must understand engineering drawings.
This course teaches the foundations of design, drafting, and drawing interpretation.
You will learn how to:
- read and interpret engineering drawings
- understand orthographic views and section views
- apply dimensioning rules
- recognize drawing symbols and industry standards
These skills ensure engineers understand how geometry is defined before applying GD&T.
Level 2: GD&T Essentials
This course teaches the GD&T fundamentals used in modern mechanical design.
You will learn how to:
- define datum references
- interpret feature control frames
- apply form tolerances
- apply orientation tolerances
- apply location and runout tolerances
- use the maximum material condition (MMC) and the least material condition (LMC)
By the end of this course, engineers can interpret ASME GD&T drawings and communicate design intent clearly.
Level 3: Advanced GD&T
This course teaches advanced ASME GD&T methods used in complex products.
You will learn how to:
- apply composite position tolerances
- tolerance patterns of holes
- use profile tolerances
- create advanced datum structures
- design for function while controlling manufacturing cost
Engineers learn how to apply tolerances correctly without increasing production cost or causing design conflicts.
Level 4: Tolerance Stack-Up Analysis
Even perfect drawings can fail if tolerance variation is ignored.
This course teaches engineers how to analyze variation across assemblies.
You will learn how to perform:
- worst-case tolerance analysis
- statistical stack-ups
- assembly loop analysis
- clearance and interference evaluation
These skills allow engineers to predict assembly performance before production begins.
The GD&T Training Program Format
The GD&T online course is fully self-paced.
Each level includes:
- short video lessons
- interactive examples
- engineering exercises
- practical assignments
Most learners complete each training course in about 10–12 hours.
Learners receive life time access, allowing them to revisit lessons whenever needed.
After completing each course, learners receive the Excedify GD&T Certification.
This certification proves engineers can apply GD&T to real engineering designs.
