This study uses an action research approach to observe teaching and learning on a computer-aided Mechanical Drawing course, in an effort to understand the development of 3-D solid model constructs using AutoCAD2000 computer application software. AutoCAD 2000 involves the application of Boolean operations in the construction of 3-D modelling, in which the 3-D model may rotate the space position at will, as well as transforming the 2-D orthographic view. This research attempts to analyse the development of 'the special thinking between the 3-D modelling and the 2-D orthographic view'.

The subjects consisted of 57 second-year students majoring in mechanical engineering at a technological university -- 11 (19.3%) being from the Department of Mechanical Drawing in vocational high schools. The subjects were divided into 11 groups.

In order to assess whether the teachers had relevant knowledge and understanding of the 3D computer-aided drawing course, pilot teaching was carried out before each unit for a total of eight units; and, following this, the researchers discussed any problems with the 11 group leaders and modified the teaching outlines and contents.

The 33 units which were designed and the findings and implications of the learner-centred approach adopted in the study are analysed in detail.
