Rapid Prototyping to Cement CAD Modeling Skills

Introduction

An important aspect of contemporary mechanical engineering education is mastery of a modern solid modeling computer-aided design (CAD) software package. This important skill is vital to future engineers’ careers and gives students immediately marketable skills for summer employment. Students also need to learn important accompanying topics of engineering design.

In 1956, Benjamin Bloom headed a group of educational psychologists who developed the classification of levels of intellectual behavior important in learning that is known as Bloom’s taxonomy.1 As seen in Figure 1, these levels within the cognitive domain become increasingly more complex and abstract. The goal in learning is to progress up these levels.

Figure 1. Bloom’s taxonomy.1

Learning to use a CAD program can be done in three progressive steps that essentially follow the first three levels of Bloom’s taxonomy, each step more open-ended than the previous: 1. Following a tutorial (gaining knowledge) 2. Modeling an existing part (testing comprehension) 3. Creating a new part from scratch (application)
