The central file collaboration mode allows users to view and edit models within the current project in real time, enabling instant information sharing and collaborative design. Using this method, multiple designers can jointly develop the same BIM information model on a shared collaborative design server. Design updates are synchronized to the project’s design server at short intervals, allowing multiple designers to work simultaneously on the same model.
1) Application of Central File Collaboration Mode
Central file collaboration in Revit relies on the use of worksets. Based on team members and their professional roles, the scope of work is defined, allowing each participant to independently complete their assigned designs.
Before starting the design, the design leader creates a central file and assigns design tasks along with corresponding access rights, effectively dividing the workset areas. Designers work within their designated areas and upload their progress to the central file, enabling the team to monitor each member’s contributions. Team members can also borrow editing permissions from one another within the workset model to facilitate cross-disciplinary collaboration, ensuring information sharing and seamless teamwork.
2) Advantages and Disadvantages of the Central File Collaboration Mode
This mode allows multiple designers to work on their respective tasks within the same model, making editing efficient and intuitive. It supports real-time information sharing and early detection of design errors, which enhances productivity and reduces costs. The collaborative nature encourages real-time communication, fostering innovation and optimization of design solutions.
However, the central file collaboration mode has some limitations:
a. It demands high-performance hardware and software for both computers and servers. Insufficient hardware resources can lead to software crashes and data loss.
b. BIM model files tend to be large, and simultaneous synchronization by multiple team members can strain the collaboration server, causing delays in syncing local files with the central file.
c. Each designer holds editing permissions for specific parts of the BIM model. For cross-disciplinary work, designers must borrow others’ editing rights, which can be time-consuming if permissions are strictly controlled. Conversely, overly lenient control may result in unauthorized or incorrect modifications.
d. Effective management is crucial. Designers need to regularly synchronize with the central file. Failure to update on time can cause discrepancies between local and central files, delaying progress and potentially leading to design errors.
3) Appropriate Use Cases for Central File Collaboration Mode
This mode supports multi-disciplinary collaboration on a shared BIM model, centralizing project data and enabling timely data exchange among designers. However, it requires high hardware and software capabilities, and managing editing permissions can be complex.
Central file collaboration is best suited for building projects or units that cannot be divided into smaller parts. For different disciplines, it is advisable to minimize reliance on this mode to reduce server load, improve efficiency, lower hardware costs, and prevent accidental modifications by other professionals.
