An Extensible Configuration Method Based on CAD Document Relationship

Abstract

The invention discloses an extensible method configuration based on a CAD (Computer Aided Design) document relationship. The extensible method configuration is characterized by comprising the following steps of firstly, determining relationship types according to objects at two ends; secondly, determining which operation relationship the relationship type belongs to according to the influence of the relationship type determined in the first step; thirdly, determining which operation interface two ends of the operation relationship associate with according to the relationship type. The extensible method configuration disclosed by the invention can be dynamically finished under the condition that services do not be restarted, and thus service functions of an CAD object relationship in a PDM (Product Data Management) system are increased, and the extensible method configuration can adapt to various flexible businesses.

Description

technical field [0001] The invention belongs to the field of dynamically expanding object relations, and in particular relates to an expandable configuration method based on CAD document relations. Background technique [0002] There are many types of relationships between CAD document objects in the PDM system. The association between components and CAD documents includes "owner", "content", "provided content", "image", "provided image" and other relationships, and CAD documents will also be constructed as Relationships such as "use relationship", "reference relationship", "variant relationship", "source and image relationship", etc., because the existing system is only a simple addition to the list of object relationships, there is no abstract classification for the existing object relationships, and it is impossible to Realizing dynamic configuration increases the complexity of existing relationship management, and the relationship cannot be expanded. Adding a business ob...

[0003] The existing CAD object relationship management solidifies the existing relationship types and the influential operations of the relationships in the system. The operations of adding new relationship types and modifying objects at both ends of the relationship cannot be dynamically realized, so when facing different enterprises and users, it is necessary to Customized development work, reorganization and analysis of existing business functions and new functions, resulting in poor flexibility and scalability of the PDM system, and each system modification will also bring stability problems
