Master Geometric Dimensioning and Tolerancing (GD&T) from scratch - GD T a Comprehensive Approach
Last updated 2022-01-10 | 4.4
- Why GD&T and a brief history- role of mechanical design and tolerances in the product development process
- Advantages of Geometric Dimensioning and Tolerancing over the +/- system
- Form Tolerances: Straightness of a centerline and of a line
- Flatness
- Circularity & cylindricity
- Profile of a line and of a surface

* Basics of technical drawingDescription
Please note: Course IN PROGRESS , New lectures are added weekly
welcome to the GD&T crash course developed by design engineers with years of experience in the automotive industry.
The course for anyone who wants to understand Geometric Dimensioning and Tolerancing in a simple and intuitive way. This course is ideal for an engineering student preparing for a mechanical engineering degree , Or for an an engineer or technician who sometimes work with technical drawings and wants to master how to read them
We will cover topics such as:
Introduction and advantages of GD&T over the + - tolerance system
From Tolerances
Straightness
Flatness
Circularity
Cylindricity
Line profile
Surface profile
Orientation Tolerances
Parallelism
perpendicularity

Course Project
in the course project you will apply the gained knowledge in the course to add GD&T tolerances to a Piston crank shaft assembly based on the function of each feature of each part!
As well as explaining from scratch what these symbols mean, we will go through the most common mistakes so you can avoid them. You will understand the concepts and test the knowledge with quizzes and assignments.
GD& T is the language of design engineers, come and join us and speak it fluently
Who this course is for:
- Mechanical engineering students, interested in design engineering
