Carry out the scene of three-dimensional modeling at multi-person synergy under, way general is at present:

1, first design idea is obtained by 3 d modeling software.

2, then calculate design idea by relation between geometry and topological data and have Lothrus apterus.

There is following limitation in above-mentioned synergic modeling method of the prior art: 1, the acquisition of design idea depends on modeling scene, but for three dimensional file management system, carry out file log on check out in on-the-spot mostly to lose.When modeling scene is lost, how only according to the old version of new file and file, obtain, compare, merge generation net result, become technical threshold, cause current three dimensional file management system cannot realize multi-person synergy three-dimensional design.2, geometry comparative approach of the prior art cannot the design idea of each cooperative nodes of Obtaining Accurate, revise a model with two people to be illustrated simultaneously, geometry comparative approach of the prior art is adopted just only to compare the amendment result of two people, now, although the difference of two amended models of people can be compared, but cannot knowing for sure, what everyone is to the concrete modification of model, also namely cannot know for sure is that the slip-stick artist of previous cooperative nodes has carried out modeling history feature and deletes, or the slip-stick artist of a rear cooperative nodes has carried out modeling history feature and has added, when a cooperative nodes carries out many places amendment to model, cause on the cooperative nodes of this design idea owing to design idea accurately cannot be corresponded to, just make the design idea that cannot compare each cooperative nodes, and then cannot merge design idea, cause multiple-person cooperative work to realize.

Limitation based on above-mentioned synergic modeling method just makes same model not modified by multiple slip-stick artist simultaneously, causes the modeling period of cad model longer.

For the problem that cad model modeling period in correlation technique is longer, at present effective solution is not yet proposed.

The collaborative method for building up of the embodiment of the present invention is obtained by the distinguishing characteristics after editing model file original in CAD editing system different cooperative nodes, achieve the modeling history feature in the three dimensional file before and after by contrast editor, obtain the design idea of each cooperative nodes, and then judged by the contrast whether conflicted to the distinguishing characteristics of different node, achieve the design idea judging different node whether to conflict, with when the design idea of different node is not conflicted mutually, distinguishing characteristics in model file after each node compiles is all merged in master pattern, when the design idea of different node is conflicted mutually, according to the selection of slip-stick artist, and the difference correspondence selected by slip-stick artist is merged in master pattern, achieve each cooperative nodes with this can edit a master pattern file simultaneously, reach many people to work simultaneously and set up cad model to shorten the modeling period of cad model, solve the problem that in prior art, cad model modeling period is longer, and then reach the effect of the modeling efficiency improving cad model.

Wherein, the flow process of the collaborative method for building up of the embodiment of the present invention can also illustrate with the form of Fig. 2, namely, Fig. 2 is the second process flow diagram of the collaborative method for building up according to the embodiment of the present invention, in the collaborative method for building up of the embodiment of the present invention, so-called distinguishing characteristics is the modeling history feature in three dimensional file, in general, only has the three dimensional file of parametric modeling Software Create just to have feature.In embodiments of the present invention, each cooperative nodes is by carrying out the feature of each file in master pattern file editing the editor realized master pattern file, particularly, the type that the feature of arbitrary cooperative nodes to model file is edited comprises deletion feature, add feature, amendment characteristic sum ignores feature, wherein, so-called deletion feature refers to that the model file after editor is compared with the model file before editor, the feature that model file after editor lacks, namely, geometric object represented by distinguishing characteristics is included in the model file before editor, but do not comprise in model file in the edited, so-called interpolation feature refers to that the model file after editor is compared with the model file before editor, additional feature in model file after editor, that is, the geometric object represented by distinguishing characteristics is not included in the model file before editor, but is included in the model file after editor, so-called amendment feature refers to the feature all existed in the model file before and after editor, but the parameter in the model file of this feature before and after editor is different, namely, all exist in the model file of geometric object represented by distinguishing characteristics before and after editor, but the parameter of this geometric object in the model file of editor front and back is different, so-called feature of ignoring refers on all four feature in the model file of editor front and back, for this category feature, does not participate in conflict and judges.For the acquisition of the distinguishing characteristics of different cooperative nodes mainly through the characteristic in the model file after this cooperative nodes editor and the characteristic in master pattern file are compared, compare different characteristic in the two model file and be the distinguishing characteristics of this cooperative nodes, illustrate, obtain the first distinguishing characteristics and the second distinguishing characteristics in the following manner: obtain the characteristic in master pattern file, obtain initial characteristic data; Obtain the characteristic in the first model file, obtain fisrt feature data; Obtain the characteristic in the second model file, obtain second feature data; Initial characteristic data and fisrt feature data and second feature data are compared respectively; Determine that the different characteristic data in the initial characteristic data that compares and fisrt feature data are the first distinguishing characteristics data; And determine that the different characteristic data in the initial characteristic data that compares and second feature data are the second distinguishing characteristics data.

The first cooperative nodes A and the second cooperative nodes B is comprised with cooperative nodes, the distinguishing characteristics got from the first model file is the first distinguishing characteristics, the distinguishing characteristics got from the second model file to be the second distinguishing characteristics be example to further illustrate the collaborative method for building up of the embodiment of the present invention, then judges that the first distinguishing characteristics and the whether afoul concrete determining step of the second distinguishing characteristics mainly comprise geometric conflicts determining step and rely on conflict determining step.Wherein, no matter be first carry out geometric conflicts judgement or first carry out dependence conflict judging, all do not affect in the collaborative method for building up that the embodiment of the present invention provides and the conflict of the distinguishing characteristics of different cooperative nodes is judged, particularly, Fig. 3 to Fig. 5 show each feature in the feature set after A node is edited and B node edit after feature set in each feature carry out the process flow diagram of clash handle:

All carry out feature interpolation to model file with A node and B node to be illustrated, as shown in Figure 3, geometric object represented by first distinguishing characteristics is be not included in master pattern file but the geometric object be included in the first model file, geometric object represented by second distinguishing characteristics is also be not included in master pattern file but the geometric object be included in the second model file, the feature set of then adding A node (namely, first distinguishing characteristics is multiple feature) and the B node feature set of adding is (namely, second distinguishing characteristics is multiple feature) carry out conflict judge concrete determining step be:

First, the geometric object (being assumed to be the second geometric object) in the geometric object (being assumed to be the first geometric object) in the first distinguishing characteristics represented by each feature and the second distinguishing characteristics represented by each feature is obtained;

Then, judge whether the first geometric object and the second geometric object intersect on geometric space, namely, judge that whether the arbitrary geometric object in the first geometric object is crossing with each geometric object in the second geometric object, if the first geometric object and the second geometric object intersect on geometric space, namely, as long as the arbitrary geometric object in the arbitrary geometric object in the first geometric object and the second geometric object intersects, then illustrate that the first distinguishing characteristics and the second distinguishing characteristics exist geometric conflicts, otherwise, if the arbitrary geometric object in the arbitrary geometric object in the first geometric object and the second geometric object is all non-intersect, then determine that the first distinguishing characteristics and the second distinguishing characteristics do not exist geometric conflicts,

Finally, first distinguishing characteristics and the second distinguishing characteristics are existed to the situation of geometric conflicts, receive user to the selection of the first distinguishing characteristics and the second distinguishing characteristics or modify instruction, and the dependence graph prestored in seeking system is selected or amended distinguishing characteristics whether Existence dependency relationship to judge user, the judged result difference according to relying on conflict performs different flow processs.As a result one: when judge user select or amended distinguishing characteristics Existence dependency relationship time, again receive user to the selection of the distinguishing characteristics of Existence dependency relationship or repair rear instruction, and user's selection or the distinguishing characteristics after carrying out secondary editor are merged in master pattern file, and log in coordination management system, obtain target cad model.Wherein, said method is adopted to carry out contrast judgement to the design idea after each node compiles equally for the distinguishing characteristics after carrying out secondary editor, to determine suitable interpolation feature, and the feature determined is merged in master pattern file, realizes working in coordination with and set up cad model.As a result two: when judge user select or amended distinguishing characteristics not Existence dependency relationship time, directly user to be selected or amended distinguishing characteristics is merged in master pattern file, and logs in coordination management system, obtain target cad model.First distinguishing characteristics and the second distinguishing characteristics are not existed to the situation of geometric conflicts, the dependence graph prestored in direct seeking system is to judge the first distinguishing characteristics and the second distinguishing characteristics whether Existence dependency relationship, and the judged result difference according to relying on conflict performs different flow processs.As a result one: when judging the first distinguishing characteristics and the second distinguishing characteristics Existence dependency relationship, reception user is to the selection of the distinguishing characteristics of Existence dependency relationship or repair rear instruction, and user's selection or the distinguishing characteristics after carrying out secondary editor are merged in master pattern file, and log in coordination management system, obtain target cad model.As a result two: when judge the first distinguishing characteristics and the second distinguishing characteristics not Existence dependency relationship time, directly the first distinguishing characteristics and the second distinguishing characteristics are merged in master pattern file, and log in coordination management system, obtain target cad model.

It should be noted that, just diagrammatically illustrate geometric conflicts in Fig. 3 and judge to conflict with dependence the sequencing judged, in embodiments of the present invention, when the interpolation of feature is all carried out for A node and B node, first can also carry out dependence conflict to the distinguishing characteristics of the two to judge, then carry out geometric conflicts judgement.

As shown in Figure 4, when the side in A node and B node carries out the deletion of feature, when the opposing party carries out interpolation or the amendment of feature or deletes, carry out feature deletion with A node, B node carries out feature deletion or feature is added or feature modification is that example is described, and is specially:

First, search default dependence graph, judge the first distinguishing characteristics and the second distinguishing characteristics whether Existence dependency relationship, judge the first distinguishing characteristics and the second distinguishing characteristics Existence dependency relationship if searched, then determine the first distinguishing characteristics and the second distinguishing characteristics Existence dependency conflict; Judge the first distinguishing characteristics and the second distinguishing characteristics not Existence dependency relationship if searched, then determine the first distinguishing characteristics and the not Existence dependency conflict of the second distinguishing characteristics.

Then, geometric object (being assumed to be the first geometric object) corresponding to A knot removal feature and geometric object (being assumed to be the second geometric object) corresponding to B node compiles feature is obtained.Similar with the collaborative method for building up shown in Fig. 3, for the situation that the first distinguishing characteristics conflicts with the second distinguishing characteristics Existence dependency, receive user to the selection of the first distinguishing characteristics and the second distinguishing characteristics or modify instruction, and search default dependence graph to judge whether geometric object corresponding to user's selection or geometric object corresponding to amended first distinguishing characteristics and the second distinguishing characteristics exists geometric conflicts; For the first distinguishing characteristics and the second distinguishing characteristics not Existence dependency situation of conflicting, then directly search default dependence graph to judge whether the geometric object that the first distinguishing characteristics is corresponding and geometric object corresponding to the second distinguishing characteristics exist geometric conflicts.

Finally, there is the situation of geometric conflicts in the geometric object that user selects or amended first distinguishing characteristics is corresponding if judge and geometric object corresponding to the second distinguishing characteristics, then again receive selection or the modify instruction of user, and user to be selected again or distinguishing characteristics after again carrying out secondary editor is merged in master pattern file, and log in coordination management system, obtain target cad model; There is not the situation of geometric conflicts in the geometric object that user selects or amended first distinguishing characteristics is corresponding if judge and geometric object corresponding to the second distinguishing characteristics, then direct by user first time select or first time carry out secondary editor after distinguishing characteristics be merged in master pattern file, and log in coordination management system, obtain target cad model; In like manner, for the first distinguishing characteristics and the second distinguishing characteristics not Existence dependency conflict but there is the situation of geometric conflicts, then receive selection or the modify instruction of user, and user's selection or the distinguishing characteristics after carrying out secondary editor are merged in master pattern file, and log in coordination management system, obtain target cad model; For the first distinguishing characteristics and the second distinguishing characteristics neither Existence dependency conflict there is not again the situation of geometric conflicts, then direct first distinguishing characteristics and the second distinguishing characteristics are merged in master pattern file, and log in coordination management system, obtain target cad model.

As shown in Figure 5, when the side in A node and B node carries out the amendment of feature, when the opposing party carries out interpolation or the amendment of feature or deletes, then same dependence conflict judgement and the geometric conflicts of adopting judges that the mode combined judges whether the first distinguishing characteristics and the second distinguishing characteristics exist conflict, concrete determination methods is set forth, repeats no more herein.

Wherein, for the situation that the distinguishing characteristics that cooperative nodes gets is multiple feature, then by each difference object that A node gets with get in B node each distinguish object and carry out respectively conflicting judging, if each distinguishes object and does not all exist and conflict each difference object with on B node on A node, determine that the first difference object and second is distinguished object and do not conflicted; For other situation, then determine that the first difference object conflicts mutually with the second difference object.
