what is Geometric Dimensioning and tolerancing (GD&T)?

Geometric Dimensioning and Tolerancing (GD&T) is a language used in mechanical engineering drawings for efficiently and accurately communicating geometric requirements for associated features on components and assemblies. Over the years, GD&T has been successfully used in various industries and sectors including automotive, aerospace, electronic, commercial design and manufacturing. Organisations that seek accuracy in the communication between engineering, designing, manufacturing and quality control prefer GD&T as their mechanical drawing standard.  


This training program will provide the participants the basic understanding about GD&T as a concept, its importance and its successful implementation. The training program will focus more on the implementation of GD&T and will dive deep into explaining some of the key benefits of GD&T which are as below:

  • Robust design
  • Improvement in productivity
  • Reduction in costs
  • Clarity in designs
  • Ease in the verification of products
