Development of Design Facilities to Facilitate Curriculum Revision of the Engineering Design Graphics Sequence

近年来，工程专业开发了一些课程，将草图和计算机应用程序作为独立的概念进行设计。开发这些程序需要下一步--将草图和计算机辅助设计整合为一个具有明确目的和目标的统一课程。课程仍然是通过在课程的一半时间里使用手工绘制实验室和使用计算机实验室来进行计算机体验来教授。承认计算机是当下的设计工具的时候到了。有必要教授草图技巧，鼓励解决和规划问题，然后使用计算机进行设计和分析的实际计算机应用。将素描过程融入计算机辅助设计教学中是十分必要的。这种教学方法将加强素描和计算机之间的联系。计算机在设计序列的第一课中的完全集成将加速学生在实体建模、有限元分析、计算机辅助制造、计算机集成制造和计算机数控领域的应用进展。实体造型的概念及其与制造领域的关系已经成为一个重要的问题，必须加以解决。这一问题将得到解决，并将利用本提案所要求的设备加强课程材料的开发。

In recent years, engineering programs have developed courses that teach sketching and computer applications to design as separate concepts. The next step is needed in the development of these programs - that of integrating the sketching and computer aided design into a unified course with clearly defined purposes and goals. Courses are still taught by using the manual drafting lab for half of the course and using a computer laboratory for computer experience. The time has arrived to admit that the computer is the design tool of the present. There is a need to teach sketching skills that encourage problem solving and planning and then using the computer for the practical computer applications of design and analysis. It is essential to integrate the sketching process into the instruction of computer aided design. This method of instruction will enhance the correlation between sketching and the computer. The complete integration of the computer in the first course of the design sequence will accelerate the students' progress toward its applications in the areas of solid modeling, finite element analysis, computer aided manufacturing, computer integrated manufacturing, and computer numerical control. The concept of solid modeling and how it relates to the field of manufacturing has become an important issue and must be addressed. This issue will be addressed and the development of curriculum materials will be enhanced with the equipment requested in this proposal.
