Abstract

Geometric Dimensioning and Tolerancing (GD&T) is a critical part in mechanical and manufacturing design. So far, the GD&T process can only be accomplished manually with limited help from computer-aided tools. The whole process is tedious. To automate the GD&T process has many positive impacts on boosting both the effectiveness of student learning and competitiveness of the manufacturing industry. A datum-based model for practicing GD&T has been developed. In this paper, the authors will introduce an algorithm to implement the datum-based GD&T model. They will also introduce a VBA (Visual Basic Applications) software tool that computerizes the execution of the algorithm. The implementation over the last two years of the algorithm in teaching GD&T has shown promising results.
