三维计算机辅助设计(CAD),是近十年来计算机领域中最活跃、发展很快的一个学术领域。它充分地利用了计算机的高速度运转、运算判断、数据分析、存储记忆和图形处理等能力,在方案的比较和选择、工艺流程和工程的计算及优化、图纸的绘制和说明、碰撞检查以及施工规划、材料统计、成本核算、技术经济评价等一系列设计过程中,都发挥了重要作 Three-dimensional computer-aided design (CAD) is the most active and rapidly developing academic field in the computer field in the past decade. It fully utilizes the computer’s high-speed operation, operation judgment, data analysis, memory and graphics processing capabilities, comparison and selection of solutions, calculation and optimization of process flow and engineering, drawing drawing and description, and collision checking. In the course of a series of design processes such as construction planning, material statistics, cost accounting, and techno-economic evaluation, important efforts have been made.
