激光扫描技术已成为记录建筑物现状的有用工具。这类文件的主要用途是评估现有建筑物（大多数是历史建筑物）的当前竣工状况。该技术还可用作新项目施工进度文件的组成部分。为了让学生掌握行业最新技术的知识，在BIM课程中向学生介绍了激光扫描。学生们得到了设备如何运作的全面演示。随后，几栋校园建筑的外墙被扫描了出来。学生们有机会看到扫描的效果。更重要的是，扫描仪生成的点云作为期末项目的一部分提供给学生。成立了五个小组，每个小组都得到了一套现有校园建筑的平面图，细节很少。然后，团队被要求从点云中进行测量，并在Autodesk Revit中对建筑物进行建模。缺乏标记的立面图并没有阻止团队相当准确地建模建筑物。点云为学生提供了大量的信息，这些信息是所提供的文件所缺乏的。尽管导航这种点云的学习曲线有点陡峭，但提取的信息帮助学生更好地理解建筑物的外壳，并欣赏激光扫描技术的真实的价值。
Laser scanning technology has emerged as a useful tool in documenting existing conditions of buildings. The main application for such documentation is to assess current as-built conditions of existing, mostly historical, buildings. The technology can also be used as an integral part of construction progress documentation in new projects. In order to equip students with knowledge on the latest technologies in the industry, laser scanning was introduced to students in a BIM course. Students were given a thorough demonstration on how the equipment functions. After that, several campus buildings’ exteriors were scanned. Students had the chance to see the scanning in action. More importantly, the generated point-clouds from the scanner were given to students as part of the final project. Five teams were formed and each team was given a set of floor plans, with minimal details, of an existing campus building. The teams were then asked to take measurements from the point-clouds and model the buildings in Autodesk Revit. The lack of marked elevation drawings did not prevent the teams from modeling the buildings fairly accurately. The point-clouds gave the students a large amount of information that were lacking in the provided documents. Even though the learning curve for navigating such point-clouds was a bit steep, the extracted information helped the students better understand the buildings’ envelopes and appreciate the real value of laser scanning technology.
