CAD (computer aided design) server device and method

Abstract

The invention provides a heterogeneous CAD (computer aided design) system integration method, which is used for reading key parameters in a CAD file generated by a CAD system, and updating the key parameters into a CAD file generated by another CAD system, wherein reading and updating do not depend on file format conversion, and interoperation of the files of the two CAD systems is not required. The method is further used for providing a universal heterogeneous CAD system data interaction method which needs no secondary development aiming at one specific CAD system and realizes 'obtaining after stating' of a common CAD system user by reading and updating the key parameters in the CAD files. Data interaction between the heterogeneous CAD systems can be automatically completed in real time, and by the aid of a database serving as a medium for data interaction between the heterogeneous CAD systems, acquired CAD file information in the database can also be used by a product data management system, an ERP (enterprise resource planning) system and other systems.

Description

technical field

[0001] The invention relates to a CAD server device and method, belonging to the field of computer-aided design (CAD), in particular to a heterogeneous CAD system integration method and device. Background technique

[0002] In the field of manufacturing and engineering, there are various computer-aided design systems (CAD systems) in use, often in different departments of the same organization, or different designers, due to considerations of usage habits, learning costs, historical resources, etc., need Simultaneously apply a variety of different CAD systems to design and develop the same product or project, so that heterogeneous CAD systems can be integrated, that is, to achieve data interaction, two-way drive, and collaborative work, which is a common requirement.

[0003] For example, designers A and B respectively design the same product ----- two parts of a bicycle, A uses AutoCAD to design the frame, B uses Solidworks to design the wheel, there are dif...
