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 reading method. The consistent reading method irrelevant to the CAD systems specifically used for generating CAD documents is provided aiming at the CAD documents generated by various heterogeneous CAD systems and is used for obtaining key parameters needed for data interaction with the documents generated by other heterogeneous CAD systems from the CAD documents. The method comprises the following steps: defining a heterogeneous CAD document information reading rule formwork; generating specific heterogeneous CAD document information reading rules according to the formwork; reading CAD drawing metadata specified in the rules from the CAD documents by a CAD document accessor compatible with various CADsystems; combining the CAD drawing metadata with existing data in the databases specified in the rules and screening and operating the data according to the provisions of the rules to obtain output parameters of the CAD documents; and presenting the output parameters of the CAD documents to the users or storing the output parameters in the databases.

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 file information reading 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 a...
