The Core Design Skills of 3D CAD in Mechanics Elements
In the past decade, The 3 Dimension Computer-aided Design (3D CAD) was developed rapidly. The feature-based 3D CAD in Mechanics is a market mainstream around the world now. Thought software had the different interface and tools, the design skills and design concept are very similar. The document analysis and experts interview were used to find the common modeling skills of 3D CAD mechanics parts that we called the core design skills. According to the core design skills, teachers can teach and assess the achievement of their students in the 3D CAD program. This study arranges the four core design skills as follow: basic concepts, sketch tools, features, modification.
