Collaborative design method, collaborative server and storage medium

The invention relates to the technical field of computer aided design, and discloses a collaborative design method, a collaborative server and a storage medium, the method comprises the following steps: obtaining a work unit divided by an engineering project and a permission group corresponding to the work unit, the permission group being used for comprising components with the same permission; and carrying out collaborative design on components in the working unit based on the permission group, determining a target working unit and updating the permission group. A large engineering project is divided into a plurality of working units with small granularity, so that the working units can be designed in parallel. Meanwhile, in one working unit, grouping can be carried out according to the authority of the component, an authority group corresponding to the working unit is obtained, the user and the component are isolated through the authority group, coupling of the component and the user is reduced, authority m
