Configuration of object division function to improvethe usability of the design 3D model in the construction stage

Abstract

The 3D model generated in the design stage is instrumental in preventing interferences and design errors during the construction process. However, it often does not consider the construction stage's activity concept, necessitating the remodeling of the 3D model for construction use. This reduces the reusability of the original 3D model, making it challenging to utilize it effectively during the construction stage. To address this issue, the authors propose a convenient function to divide the 3D model into construction activity units while retaining the attribute information. Although commercial CAD software like Dynamo has a 3D model division function, its use is complicated and requires additional software besides the 4D system for 4D simulation in the construction stage. The authors introduce a methodology and module that utilize the bounding box concept to simplify the division process after importing the 3D model into the 4D system. This eliminates the need for separate CAD software and allows for direct division into activity units within the 4D system and simultaneous simulation. The new division function is expected to improve the utilization of 3D models during the construction stage.
