Background
A family table is a collection of many similar parts (or assemblies or features) that are very similar in structure but differ slightly in some parts, such as size or detailed features, etc. Typical examples are standard parts such as screws, which have hundreds of different specifications in a standard series, but have the same shape, and we refer to such parts as "parts family".

Referring to fig. 1 of the specification, an embodiment of a family table management and integration method for CAD model construction provided in the present application includes the following steps:
s010, adding a group table management object, wherein the group table management object specifically comprises: a family table master object, a family table version object.
S020, adding a group table instance object, and storing the association relation between the group table version object and the instance model.
S030, adding a generic relation object of a family table, and storing the generic relation between the generic model and the instance model.
S040, a family table custom parameter object is newly added, and the category of the custom parameter selected by the CAD tool end is stored and bound with the family table main object.
S050, a family table custom parameter value object is newly added, numerical information of the custom parameter is stored, the numerical information is associated with the family table custom parameter object, and the numerical information affects the generated instance model.
S100, constructing a family table of the target part by using the family table function of the CAD software. The first model of the family table is a generic model of the target part. The generic model contains family table information.
And S200, uploading the generic model to a PDM system and adding the generic model into a classification library, and calling the generic model by a CAD end through a classification library interface. Based on the generic model, setting different custom parameters to generate a plurality of instance models. The custom parameters include specifications and material properties of the part.
And S300, when the instance model is used for assembly, the family table is checked in, and the appointed instance model is displayed in a CAD work area. Generic relationships between the generic model and the instance model are shown by a "tree" like structure.
S400, if the instance model has detected modification, the generic model corresponding to the instance model is automatically detected modification and updated.
S500, if the generic model has detection modification, the instance model with modification influenced by the generic model needs to be manually detected, updated and re-detected. If the affected instance model is not detected, prompting that the modification to the generic model cannot be saved.
Specifically, a family table essentially manages a data model with a spreadsheet, consisting of rows and columns. Each row represents an instance model, and the columns contain the name, properties, dimensions, and various parameters of the instance. As shown in fig. 2, in the CAD tool, the first instance in the family table, also called the source model, is actually the current model, called the "generic model", is the parent model of all other instances, the values of all items in the first row are also directly called the current value of the current model (the values of all items in the first row can be directly modified if the model is to be modified), and all other instances, called "instance models", are all user-defined according to the actual needs. When an instance is selected to be generated through the family table, a new drawing model is not generated, and parameters of the instance are recorded on the model.
Distinction between generic models and generated instance models of family tables: the generic model has family table information, and the example model has no family table information. Preferably, in reality, each instance of the family table corresponds to an actual material, so in a PDM system, it is necessary that each instance be associated with a component, rather than all instances being associated with the same component. Because the generic model can also be assembled as an instance, the name of which is the generic model name, and the parameters are parameters of the generic model, the generic model can also be regarded as a special instance associated with the component.
The part family is created through a 'family table', which is not instantiated first, and a family table generic model is managed in the system. When the generic model is called, a selection instance dialog box (OOTB) is popped up, and the instance model with the corresponding specification is generated by redriving according to the selected specification.
After the examples of the family table are assembled, the objects are checked in, corresponding example objects are generated in a working area, a family table source model and an associated example model can be checked through a family view, and the association relation is displayed through a tree structure.
If the instance model is detected in the system, the generic model is automatically detected synchronously and modified, because the parent item (generic model) of the instance model is necessarily updated after the instance model is modified.
If the generic model is detected and modified in the system, the affected instance model needs to be manually detected, and the instance model is detected again after being updated. If no affected instance model is detected, a prompt is required to fail to save the modifications to the generic model.
The attributes in the family table may inherit the value of the parent or may be custom values, so that when an instance is checked in, the actual attribute value of the instance needs to be submitted. For example, in the family table, different instances correspond to different material specifications, so that the material specification attribute of the instance model is different from the source model, and other attributes not defined in the family table inherit the attribute of the generic model.
In another implementation of this embodiment, the following operations are performed for integrated management of the family table:
1. and (3) adding a group table management object, carrying by adopting a Master and version object management and control mode, wherein the group table Master object is defined as: erd. Closed. Pdm. Entity. Epm Sep Family Table Master, family table version object is defined as: erd.
