### Parameter-Based and Visual Application of Historic Building Information  
The 3D visualization of building information modeling (BIM) has become a key factor in communication [14]. Throughout the process of building production and construction, and the visual modeling of the same information rich model, all project participants,including experts and non-experts, can discuss the design in a common 3D model, and such interaction can enhance collaboration and understanding among participants and improve the old workflow. BIM technology has currently been extended to the restoration and conservation of historic buildings and other related issues, and many studies have used BIM technology for the investigation of historic buildings, for the early stage of modeling and analysis, and for management and simulation reproduction after modeling. Unlike new buildings, historic buildings are existing buildings that must be reconstructed with reverse engineering technology; thus, some research has digitalized historic buildings to collect space information by modeling with point cloud information, as obtained from 3D scanning in combination with 3D information modeling [15]. Such models are transferred into structured and parameterized visual models, which can provide useful information to experts including designers, architects, owners, and historians, and are very useful for traditional building construction management. Architecture and urban design have always focused on the concept of visualization and materialization. Visualization through building information modeling (BIM) can interact with models in a fast and intuitive manner. Although BIM-related applications have been widely used, there are still challenges in the costs and time resources required to develop and maintain the BIM models of historic buildings. Moreover, user proficiency in BIM and data interactivity are also obstacles in the development. In order to overcome these challenges, the first issue to address is data transmission. It is pointed out that data transmission may be solved through parameter-based external tools (for example, Dynamo) or Application Programming Interfaces (API), as they may act as information exchange links between BIM models and external data sources. In addition, the processes of the automatic maintenance of the model and data transmission may also reduce the costs for model-related settings and maintenance [16]. [PERSON] et al. [17] proposed a virtual environment restoration system for the reconstruction and restoration of synagogues, which emphasizes the use of parameter-based and adaptive controls to effectively reduce the workload of future reconstruction and to provide a new technology and opportunities for the conservation of historic buildings. [PERSON], [PERSON] et al. [18; 19; 20] proposed a system incorporating BIM to aid the traditional restoration process of historic buildings. The system records the restoration process information in the building life cycle and builds a BIM model containing building health records and the restoration information of components to assist in the traditional construction process of traditional historic buildings, as well as the communication process between construction end and the design end. In addition, [PERSON], [PERSON] et al. developed plug-in applications that can instantly return information to the construction end. Meanwhile, the visual models and parameter-based component design improve the efficiency and smoothness of the repair design process and construction communication process, which increases the continuity of the life cycle of historic buildings and the possibility of preserving cultural heritage. In addition, England has acquired a set of knowledge and experience in the application of BIM to historic buildings and put forward a series of practical guidance items for the detection, management, and care of historic buildings and their environment, as well as professional technology regarding the surveys, measurements, and recording of historic buildings.
