Problems solved by technology

[0010] This "what you say is what you get" feature of the solution of the present invention makes this solution overcome the shortcomings of the prior art for heterogeneous CAD system data interaction: 1) the user generates a statement similar to natural language according to the needs Rules, execute the rules to get the desired result of the user, and do not need to do any secondary development work for the CAD system; 2) No matter what kind of CAD system, the composition and execution method of the rules are consistent, so this method is suitable for all kinds of CAD systems. Heterogeneous CAD systems are universal; 4) There is no need for file format conversion, and it is not affected by the insufficient support of unified standards by various manufacturers; 4) The execution of rules is carried out in a user-controllable manner, and data interaction can be completed in real time

Abstract

The invention provides a heterogeneous CAD (computer aided design) document information updating method. The method is used for updating the parameters obtained from other heterogeneous CAD documents or the parameters from databases into the CAD documents so as to realize external parameter drive of the CAD documents. The method comprises the following steps: defining a heterogeneous CAD document information updating rule formwork; generating specific heterogeneous CAD document information updating rules according to the formwork; querying data in the databases according to the provisions of the rules to obtain the result data needing to be updated into the CAD documents; and updating the result data into the CAD documents by a CAD document accessor compatible with various heterogeneous CAD systems so as to drive other information in the CAD documents to change, wherein the application time of the rules can be specified so as to automatically update the CAD document information in real time.

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 method and device for updating heterogeneous CAD document information. 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...
