Rule-based automation algorithm for generating 2D deliverables from BIM

초록

Efficient generation of two-dimensional (2D) deliverables from building information models (BIM) entails remarkable challenges, impacting project productivity. To address this issue, BIMDrawGEN, a rule-based algorithm, was developed in this study to streamline the creation of essential 2D deliverables during the design development phase. This approach involves an analysis of the BIM design process, resulting in the derivation of 76 automation rule sets for generating logically defined 2D deliverables from BIM data. A prototype add-in interfacing with BIM authoring tools was developed to validate the model, demonstrating significant reductions in work nodes and time by 94.54 % and 93.26 %, respectively, for BIM-based drawing creation. Significant reduction in working hours, from nearly a week to under half a day, using BIMDrawGEN enhances both industrial and academic outcomes. This efficiency enables designers to focus more on design rather than documentation. This study identifies and addresses inefficient processes in BIM, demonstrating that targeted automation could significantly improve design quality and productivity.
