About Us
We are passionate about bridging the gap between GD&T Theory and Practice
Founder
Nasir Ilyas is a National Physical Laboratory (NPL) certified instructor with over a decade of experience delivering GD&T training and consultancy to American engineering organisations and international clients.
Specialising in ASME Y14.5 and ISO GPS, he has trained hundreds of engineers across multiple industry sectors, supporting teams in applying tolerancing with clarity and confidence. Our courses focus on bridging textbook theory with practical application ensuring engineers, designers, and inspectors can apply tolerancing effectively in their daily work.

Geometrical tolerancing
Our Vision & Mission
“Bridging the Gap Between Theory and Practice”
Bridge Theory and Practice — link classroom learning to the realities of design, manufacturing, and inspection. Our training goes beyond textbook theory to show how tolerancing decisions impact real parts, processes, and quality outcomes across multiple sectors.
Simplify Standards — make ISO GPS and ASME Y14.5 clear and accessible by breaking down complex terminology and rules into practical, easy-to-understand concepts. We cut through the confusion that often arises because these topics are not taught well at university or college, ensuring engineers build a solid foundation.
Enable Engineering Excellence — empower engineers, inspectors, and organisations with practical skills to apply geometrical tolerancing effectively. The result is clearer design intent, improved communication across teams, fewer errors, and more efficient, cost-effective production.
