摘要
本文基于工程实际应用，对三维数字化设计从协同设计和精细化设计、碰撞检查等方面进行了研究论述，提出各专业设计人员在一个协同的环境下建立三维数字化模型，设计人员通过多方位查看浏览，可以直观地了解其他专业的设计内容，再通过碰撞检查，可以很容易地检查出各专业之间的碰撞，及时进行设计修改或调整，最大限度地减少或杜绝硬碰撞，将设计中的差、错、碰、漏等问题降至最低，进一步提高设计质量。
Abstract
Based on the practical application, the study are discussed about 3D digital design from collaborative design and fine design, collision detection and other aspects. All the designers work in a collaborative environment to build 3D digital models, and they can intuitively understand other professional design content, and easily check out the collision between the various professionals through the collision check, timely modify the design to minimize or eliminate the hard collision, the design difference , wrong, touch, leakage and other problems, to further improve the design quality.
