3D property formation has become an important solution to provide a more comprehensive and accurate representation of the property’s physical characteristics than traditional 2D property formation. Despite the numerous benefits of the 3D property formation, there is a need for more detailed descriptions of 3D cadastral data delivery between the involved actors to ensure efficient and effective collaboration. In particular, the practical difficulties are when/what related 3D cadastral information and models should be exchanged and stored from/to whom. Therefore, to address these issues, we propose a lifecycle 3D property formation process with four phases by designing an IDM process, which is an international open BIM process standard. In the purpose of forming a Swedish lifecycle 3D property formation process, the IDM process has been applied through organizational, legal and technical aspects, including identifying actors and their roles and values, gathering 3D property formation requirements, defining the data exchange requirements and designing the process map. Moreover, a case study was used to specify the Swedish lifecycle 3D property formation process and information delivery between stakeholders in the IDM. The aim is to facilitate a standardized and unambiguous digital 3D property formation procedure on a national level in order to improve and enhance the digital Swedish Cadastral and Land Administration Systems, but the process is quite generic and could also be applied in other countries.

3D地层地层已经成为提供比传统2D地层地层更全面、更准确地表示地块物理特征的重要解决方案。尽管 3D 财产形成有很多好处，但仍需要对相关参与者之间的 3D 地籍数据传输进行更详细的描述，以确保高效和有效的协作。特别是，实际困难是何时/什么相关的 3D 地籍信息和模型应该从/向谁交换和存储。因此，为了解决这些问题，我们通过设计国际开放式 BIM 流程标准 IDM 流程，提出了具有四个阶段的生命周期 3D 属性形成流程。在形成瑞典生命周期3D财产形成过程的目的中，IDM 流程已通过组织、法律和技术方面得到应用，包括识别参与者及其角色和价值、收集 3D 属性形成要求、定义数据交换要求和设计流程图。此外，案例研究用于指定 IDM 中利益相关者之间的瑞典生命周期 3D 财产形成过程和信息传递。目的是在国家层面促进标准化和明确的数字 3D 财产形成程序，以改进和增强数字瑞典地籍和土地管理系统，但该过程非常通用，也可以在其他国家/地区应用。定义数据交换要求并设计流程图。此外，案例研究用于指定 IDM 中利益相关者之间的瑞典生命周期 3D 财产形成过程和信息传递。目的是在国家层面促进标准化和明确的数字 3D 财产形成程序，以改进和增强数字瑞典地籍和土地管理系统，但该过程非常通用，也可以在其他国家/地区应用。定义数据交换要求并设计流程图。此外，案例研究用于指定 IDM 中利益相关者之间的瑞典生命周期 3D 财产形成过程和信息传递。目的是在国家层面促进标准化和明确的数字 3D 财产形成程序，以改进和增强数字瑞典地籍和土地管理系统，但该过程非常通用，也可以在其他国家/地区应用。
