Automated modeling to high level-of-detail composite object using spatial BIM objects and properties

Building Information Modeling (BIM) procedures for geometric and information modeling are laborious and time-intensive. Traditional methods focus on individual objects, with designers manually modeling each item. This paper presents an approach to high Level of Development (LoD) indoor spatial modeling using space-centered BIM composite objects. By automatically positioning these composite objects within a space, designers can achieve more efficient indoor design modeling early on. The study defines BIM composite objects and demonstrates a visual-language-based parametric modeling process integrated into BIM authoring tools. The process involves inputting data, selecting and placing interior design objects, and deriving the indoor layout. The feasibility of the space-centered design approach is demonstrated in interior architecture, showcasing its potential to reduce inefficiencies and enhance the modeling process, especially in the initial design stage. This approach not only streamlines the early design phase but also reduces inefficiencies across a wide range of applications. The demonstration is implemented and presented in the paper.
