Family table (Figure 1) is to use a table to manage all the data. However, we can see some examples of this table the value of certain items is the same, such as M3x4/M3x5/M3x6/M3x8/M3x10 five instances, in addition to the different values of length L this one, the other the The value of the same item, M2x5/M3x5/M4x5 difference between these three instances of relatively large, but also has a similar value of the item. Therefore, we can then change to, see Figure 2: Figure 1 Figure 2 In this table, just take the four items, with all of these four items will be combined M2 as an example of the specification, all the specifications together for the M3 one instance, the Ministry of M4 specifications together into one instance. The remaining length L this one does not exist in this table. The next three tables were doing this, as shown in Figure 3: Figure 3
The three tables were in the previous table (Figure 2) in the instance of the M2, M3, M4 is associated, in Excel, the construction of a link is in the PROE, the M2 is open instance, in this instance to build a family table , family table is the content of the table on the map M2 (M3, M4 empathy). This is the level of family table, instances M2, M3, M4 parent family table where the family table, the other three family table is a list of its subclasses. Similarly, sub-family table can have its sub-family table, family table is also the parent can also have its parent family table, that is, family table can be multi-level cascade, see Figure 4: Figure 4, but note : the same object (same size / parameters / features / parameters of the table / UDF / component ...) can only appear in the same branch of the family with a table. Such as size K, it appears in the second group in Table 1, then, in the second group all instances of Table 1, three family table defined (and thisSome examples of family table is more defined in the lower family table) in no longer use it, re-define its superior family form (and more superior family form) can no longer use it; but if it features in the definition of the secondary attachment K K family table instances where it did not exist and K in the secondary group list appears, then it can appear in two family table K (or the family table instance of a class defined by lower family table) years.
