Description
Technical field
The present invention relates to manufacturing informatization technical field, specifically a kind of components replacement side based on Feature Mapping
Method.
Background technique
In order to improve the design efficiency under large-scale customization, experienced engineer has often previously been designed using borrow
The product crossed carries out deformation design.
In product based in three-dimensional design process, it is mainly concerned with one of content, is exactly the replacement of components.Tradition
Components alternative mainly according to the space coordinates of previous part and the creation mode of components, it is suitable to carry out
Replacement.However meeting is done so since it is desired that constraining the relationship of current design part and part to be replaced, so that creation replacement
Part cost it is relatively high.
Summary of the invention
The purpose of the present invention is to provide a kind of components replacement method based on Feature Mapping, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the invention provides the following technical scheme:
A kind of components replacement method based on Feature Mapping comprising the steps of:
A, components to be replaced are specified；
B, the linked character of components to be replaced is obtained；
C, replacement components are imported；
D, it is mapped according to the linked character obtained；
E, the incidence relation of part to be replaced is obtained；
F, it is replaced according to the information in the presence of the Feature Mapping and incidence relation created；
G, components to be replaced are deleted.
As further technical solution of the present invention: the step A is specifically that in the three-dimensional model, selection needs to be replaced
Part or component.
As further technical solution of the present invention: in the step B, in the three-dimensional model, components include a large amount of
Feature only has occurred associated feature with other components or information and is just obtained, without obtaining components
In all feature.
As further technical solution of the present invention: the step C is specifically that the components replaced will be needed to lead
Enter, for the Feature Mapping between specified replacement components and components to be replaced.
As further technical solution of the present invention: the step D is specifically: according to specified components and the pass of acquisition
Join feature, specify the corresponding relationship of the feature in replacement part between part to be replaced, completes replacement part and part to be replaced
Between Feature Mapping.
As further technical solution of the present invention: the step E is specifically: according to previous components, to it
Relevant content is obtained, including assembly relation, markup information relationship, knife rail information and other parts or letter
Cease associated relationship.
Compared with prior art, the beneficial effects of the present invention are: present invention employs the technology solutions based on Feature Mapping
To the higher problem of current design part requirements when components are replaced；After this method, designer only needs to pay close attention to zero
How component reaches design requirement, then is replaced by Feature Mapping to components.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's every other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
A kind of components replacement method based on Feature Mapping comprising the steps of:
A, specify components to be replaced: in the three-dimensional model, selection needs part or component to be replaced；
B, the linked character of components to be replaced is obtained: according to the part of selection or component retrieval its linked character, in three-dimensional mould
In type, components include a large amount of feature, still, do not needed when being replaced by each of which feature all with it is to be replaced
The feature of components is all mapped, but linked character is mapped；In the three-dimensional model, part or component are not lonely
It is vertical existing, but have to other parts or component related associated, therefore it only needs when replacing by these and other zero
Part has related associated feature to be mapped, and new parts or component, replacement in the three-dimensional model can be completed；Include among these
Feature, the feature for creating size and markup information (such as PMI) for creating assembly (constraint) relationship；For recording knife
Rail information etc. generates associated feature with other components or information；Only it is associated with other components or information
Feature just obtained, without obtaining all feature in components；
C, replacement components are imported: the components replaced will be needed to import, for specified replacement components and to be replaced zero
Feature Mapping between component；
D, it is mapped according to the linked character obtained: according to specified components and the linked character of acquisition, specifying replacement
The corresponding relationship of feature in part between part to be replaced completes the Feature Mapping between replacement part and part to be replaced；
E, obtain the incidence relation of part to be replaced: the components deposited in the three-dimensional model are relevant with other information
, therefore according to previous components, to it, relevant content is obtained.It among these include that assembly is closed
System, markup information relationship (describing the information of relationship between some or multiple features), knife rail information are (because knife rail information is sustenance
Created in the feature of threedimensional model) etc. relationship with other parts or information association；
F, it is replaced according to the information in the presence of the Feature Mapping and incidence relation created；New replacement part is come
It says, when being loaded into previous threedimensional model, is not related with any components or information, therefore in three-dimensional
It is to belong to free state in model；By in step E, incidence relation contained in the previous part to be replaced of acquisition, to obtain
Feature included in the incidence relation is taken, and passes through Feature Mapping for the incidence relation institute of the feature of replacement part and former part
The feature for including is replaced, so that the incidence relation of creation new parts and other components in threedimensional model according to this, finally makes
It becomes the state fully associative with other components and information from free state；
G, components to be replaced are deleted；Since replacement components have been completed its in a three-dimensional structure fully associative, not
Former part to be replaced is needed again, it is therefore desirable to it is deleted, it here, can determines according to actual conditions zero to be replaced
Part deleted opportunity, but before deletion, it should be ensured that when replacing the part, obtain information needed.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
