Title:
CAD COLLABORATIVE DESIGN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/015613
Kind Code:
A1
Abstract:
The present invention relates to a CAD collaborative design system, for storing CAD files according to a timeline, and that facilitates restoration and review of versions created, modified, and updated at different times. The system stores the CAD files by means of summary files and an incremental databases, thereby reducing data transmission volume, ensuring accuracy of file restoration, and improving the file management efficiency of the entire CAD system. The present invention further provides a new referencing method, enabling a CAD drawing engineer to easily filter the content of a referenced document, and to share a referencing rule customized by themselves with other collaborating parties. A multi-layer display mode prevents the numerous problems caused by existing external reference nesting techniques, and increases the flexibility of referencing an external file. The present invention copies and superimposes referenced content (which can be filtered and selectively displayed) on a CAD file currently being edited, thereby achieving editing and viewing changes of the referenced content in a synchronized manner, and facilitating and improving the efficiency of collaboration.
