Step 7：According to the title of x-th of part, the configuration is inquired about to table, obtains the title with x-th of part
X-th of the matching part name mutually to match；
Step 8：X-th of matching zero according to corresponding to described x-th matching part name judges x-th of matching part name
Part whether there is in the product form table comprising described x-th part for matching part, if in the presence of from the mould
The part that part is matched by described x-th matching part or comprising described x-th in type storehouse is called in Pro/E softwares, by institute
State x-th called in of model and x-th of matching part or the part comprising described x-th matching part forms xth
Individual Matching Model pair；By x-th of Matching Model to obtaining corresponding x-th of configuration interface pair；And perform step 9；If no
In the presence of, then x+1 value is assigned to x, and judge whether x=m sets up, if so, then exit execution；Otherwise return to step 5；
Step 9：Inquired about respectively from the interface table x-th of configuration interface to the presence or absence of in configuration interface in table,
If in the presence of execution step 10, if being not present, then it represents that x-th of configuration interface is determined so as to return to the interface missing
Adopted module adds x-th of configuration interface pair again；
Step 10：According to described x-th configuration interface to being inquired about in the configuration constraint table, obtain described x-th and match somebody with somebody
Interface is put to x-th corresponding of configuration constraint；And the constraint of the Matching Model pair is converted in Pro/E softwares, so as to
Complete the assembling of x-th of Matching Model pair；
Step 11, x+1 value is assigned to x, and judges whether x=m sets up, if so, then represent to complete the parameterized model
Or the assembling of non-parametric model, and exit execution；Otherwise, return to step 5 performs.
