In order to solve the problems such as difficulty in implementing design standards, lack of efficient collaborative system, and lack of effective control over printing and digital signatures.We built a private cloud-based design collaboration management platform. It combines the actual needs of designers and integrates design standards, process management and project management. It achieves multi-disciplinary cooperative design, promotes standardization of drawings, digitalizes process information, and enables real-time synchronization and data sharing, thus further improves design quality and management level.
