CAD三维技术与形态构成

随着CAD技术的发展,三维图形已由过去的辅助作用,迅速扩大到现在贯穿于设计和生产的全过程。针对当前三维CAD技术发展的实际情况,笔者从理论和应用的角度对CAD建模技术和建模方法作了系统、全面、深入的分析。根据三维构思中形态设计的原理,探讨了将构成理论与三维CAD应用相结合,利用三维CAD系统培养学生抽象思维、形象思维和创新思维的教学模式。提出了要综合形态构成的基本要素与CAD三维建模的方法,并通过实例将设计的理念引入到教学过程中。

3D CAD Technique and Shape Forming

With the development of CAD technology, 3D solid model has been playing key role in the whole process of design and production instead of the secondary position in the past. According to the actual and current situation of CAD technology, we made a systematic and deep analysis of CAD modeling technology and method from the point of theory and application. Also according to the principle of shape design in 3D modeling, we discussed about the teaching modes which can train the abstract, visualization and innovation thinking by using 3D CAD system through the combination of forming theory and 3D CAD application. We put forward a method which can combine the basic elements of shape forming and CAD modeling, and we introduced the thought into the teaching by examples.
