About This Course
Geometric Dimensioning and Tolerancing (GD&T) Training in Bangalore at CADD Mentors covers both ISO 1101 and ASME Y14.5 standards — the engineering drawing language used in every precision manufacturing and product development environment. This GD&T course teaches engineers and CAD professionals how to read, interpret and apply GD&T controls to mechanical drawings, enabling clear communication of design intent across design, manufacturing and quality teams.
CADD Mentors provides GD&T training from our HSR Layout centre in Bangalore. Online training is available for professionals across India.

Curriculum
What You Will Learn in GD&T Training
Purpose of GD&T: communicating design intent beyond ±tolerance dimensions
ISO 1101 and ASME Y14.5 drawing standards: rules, symbols and interpretation
Feature of size, actual mating envelope and maximum material condition (MMC)
Form controls: flatness, straightness, circularity and cylindricity
Orientation controls: parallelism, perpendicularity and angularity
Position and true position: locating holes, slots and features on a pattern
Runout controls: circular runout and total runout for rotating components
Datum reference frames: primary, secondary and tertiary datum selection
Tolerance stacking and worst-case analysis for assemblies
Reading and interpreting GD&T on engineering drawings for inspection and manufacturing
Course Structure
GD&T Training — Syllabus Modules
Module 1 – Introduction to GD&T and Drawing Standards
Why GD&T, history, ISO 1101 vs ASME Y14.5, basic rules and the GD&T symbol set.
Module 2 – Datums and Reference Frames
Datum targets, datum reference frames, primary-secondary-tertiary hierarchy and how datums constrain geometry.
Module 3 – Form Controls
Flatness, straightness, circularity and cylindricity — independent of datums — with drawing examples.
Module 4 – Orientation Controls
Parallelism, perpendicularity and angularity with respect to datums for flat and cylindrical surfaces.
Module 5 – Position and True Position
Locating features with true position, bonus tolerance at MMC/LMC, composite position and pattern location.
Module 6 – Profile and Runout Controls
Profile of a line and surface, circular and total runout for shafts, hubs and bearing seats.
Module 7 – Tolerance Stacking and Assembly Analysis
Worst-case and statistical tolerance analysis for assemblies — applying GD&T to real-world fit and function.
Module 8 – Interpretation and Inspection
Reading production drawings, CMM inspection context and communication between design, manufacturing and quality.

Frequently Asked Questions - GD&T Training
- Is GD&T training available in Bangalore at CADD Mentors?
- Yes. GD&T training is available from our HSR Layout centre in Bangalore. Classroom sessions are batch-based and online training is also available.
- What is GD&T used for?
- Geometric Dimensioning and Tolerancing (GD&T) is the engineering drawing language used to communicate precise dimensional requirements between designers, manufacturers and quality inspectors. It replaces ambiguous ±tolerances with geometrically defined controls that guarantee part function regardless of where it is manufactured.
- Which standard is covered — ISO or ASME?
- The course covers both ISO 1101 (used in Europe and India) and ASME Y14.5 (used in the USA and global OEM supply chains). Differences between the two standards are highlighted.
- Do I need CAD software knowledge to learn GD&T?
- GD&T is primarily a drawing interpretation and annotation skill. Some practical exercises use AutoCAD Mechanical and SolidWorks for applying GD&T callouts. Basic familiarity with 2D drawings is sufficient to start.
- How long is the GD&T course?
- The GD&T course at CADD Mentors is approximately 30 hours, covering all fourteen GD&T controls, datum theory, MMC/LMC, tolerance stacking and inspection interpretation.
- Can I take the GD&T course alongside other Mechanical CAD courses?
- Yes. GD&T is often taken alongside AutoCAD Mechanical or SolidWorks as a complementary skill. It is also available as a standalone short course for professionals.
