Problems solved by technology

[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 new modification will also bring stability problems to the system

Embodiment

[0018] A scalable method configuration based on CAD document relationships, the steps are as follows:

[0019] Step 1: Determine the relationship type according to the objects at both ends;

[0020] Step 2: Determine which type of operational relationship the relationship type belongs to according to the influence of the relationship type determined in step 1;

[0021] Step 3: According to the relationship type, determine which type of operation is associated with both ends of the operation relationship.

[0022] In this embodiment, the specific program realizes the flow:

[0023] Step 1: the system automatically updates the configuration file of the CAD document object relationship into the system memory;

[0024] Step 2: The system reads the configuration file when creating CAD document relational data, and generates different object relationships according to the object types at both ends of the relationship in the configuration file;

[0025] Step 3: Operate the CAD doc...

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 extensible method configuration based on CAD document relations. Background technique [0002] There are many types of relationships among CAD document objects in the PDM system. The association between parts and CAD documents includes relationships such as "owner", "content", "provided content", "image", and "provided image". CAD documents will also be constructed into "Usage relationship", "reference relationship", "variation relationship", "source and image relationship" and other relationships, because the existing system simply adds and lists the object relationship, and does not abstract the existing object relationship. The realization of dynamic configuration increases the complexity of existing relationship management and the relationship cannot be expanded. Adding a type of business object will add a type of relationship and related b...
