This paper presents a novel system, named AHMsys, designed to automate the process of generating 3D Heating, Ventilation, and Air Conditioning (HVAC) models from 2D Computer-Aided Design (CAD) drawings, a key component of Building Information Modeling (BIM). By automatically preprocessing and extracting essential HVAC object information then creating detailed 3D models, our proposed AHMsys significantly reduced the 20 percent work schedule of the BIM process in Akila. This advancement highlights the essential impact of integrating AI technologies in managing the lifecycle of a digital representation of the building.
