BIM-based construction drawing checking system, the system checks whether the imported BIM 3D model meets the key domains, semantic rules, and data standards, which are established by analysing related specifications. By predicting architectural design errors, associating problematic components, and providing visual positioning, this process avoids manual tedious and repetitive work that can effectively improve the efficiencies. The model will be loaded into the CIM(City Information Modeling)platform once it passes the checking.
