Geometric Dimensioning and Tolerancing
This course is one of five modules stackable for the Graduate Diploma in Precision Engineering, specialising in Mechatronics.

This course aims to provide students with fundamental knowledge and practical skills on the subject of Geometric Dimensioning and Tolerancing (GD&T). The course is conducted in an interactive way with case studies and hands-on experiments.

GD&T is a graphic language used by mechanical designers, engineers, and quality inspection operators to effectively and accurately communicate with one another through detailed drawings. It defines the geometry of mechanical parts without any ambiguities through symbols for geometric dimensions, tolerances and relative positions among features and datums. With GD&T defined drawings, desired forms and fits can be realised. This ensures the intended function of the parts and assemblies.

Why This Course

GD&T is a powerful communication tool used in the precision engineering industry. These days, more companies are required to generate drawings that are dimensioned and toleranced with GD&T. This course is conducted by instructors with strong industrial experience in using GD&T. It also includes case studies discussions and intensive hands-on sessions to enhance the participants’ GD&T understanding.

Who Should Attend

This course is recommended for

  • Mechanical designers and engineers
  • Quality manufacturing inspection operators, engineers and managers
  • Those interested in understanding and applying engineering drawings

    Eligible for SkillsFuture Enterprise Credit (SFEC)

    SkillsFuture Enterprise Credit (SFEC)

    The SkillsFuture Enterprise Credit (SFEC) was first introduced during the Singapore’s Budget 2020 and then recently expanded to a larger group of employers in Budget 2022. It encourages employers to invest in enterprise transformation and capabilities of their employees. Eligible employers will receive a one-off S$10,000 credit to cover up to 90% of out-of-pocket expenses on qualifying costs for supportable initiatives, over and above the support levels of existing schemes.

    Submission of SFEC Claim

    Employers are required to submit their SFEC claims manually via its microsite if they fulfil any of the following scenarios:

    • Employers have sent their foreign employees (excluding foreign employees who hold Long-Term Visit Pass Plus) for training on a SFEC-eligible course;

    Employers can only submit the claims for SFEC after their employees have completed the training course(s). Click here to download the SFEC Claim e-guide.
    NOTE: You will require a Corppass account with "EPJS_User" role assigned prior to login to your account to manage your claims.

    If you are unsure whether your company is eligible for SFEC, you may submit an enquiry to Enterprise Singapore (ESG) via here for their response.
