Description
Technical field
The present invention relates to a kind of method and system of the engineering collaborative design based on pel, relate in particular to collaborative design method and the system of the engineering drawing of preserving in the mode of electronic document, further, the collaborative design method and the system that relate to the drawing that uses the generation of CAD graphics software.
Background technology
Collaborative design technology is a focus of current design industry research.Along with China's entry into the WTO, the intensified competition of industry, owner is more and more higher to time requirement and the quality requirements of design, and design alteration is also increased.On the other hand, the method for designing of design companies still rests on the design of traditional unit, regularly links up, and the information interaction inefficiency between specialty, is touched, lacked phenomenon and generally occur Wrong, missing, has had a strong impact on progress and the quality of engineering; Due to individual task often individual complete separately, cause the total quality of project uneven, different style, owner's suggestion is very large.
Under the background of computer networking technology develop rapidly, personal computer is connected with each other, by carrying out combination with CAD software, cooperate in the common cyberspace mode of operation of complete design task of a plurality of people occurs.According to the difference of CAD software, be divided into two dimension collaborative and three-dimensional collaborative.Current domestic construction party is generally accepted is the two-dimentional drawing that has a set of standard of strictly publishing picture; Three-dimensional is worked in coordination with very large advantage aspect the validity of information accuracy, cooperation, but because the problem of the standard of publishing picture can't extensively be promoted at present, major part also just rests on the schematic design phase.Synergistic method involved in the present invention, belongs to the collaborative category of two dimension.
The collaborative method that adopts often of two dimension comprises at present: external reference is collaborative and figure layer is collaborative.External reference refers to a design document, and a local part with reference to another one file is recorded in the linking relationship of this external file and the position relationship of quoting in current file.Like this, when external file changes, quote other file of this file, can automatically be upgraded.External reference is collaborative is a kind of simple and effective collaborative design method, uses the intrinsic function of CAD software just can complete.Between Team Member, mutually quote achievement, cooperatively interact, just can reach the object of sharing out the work and help one another, jointly completing multinomial design objective.The collaborative concept that involves figure layer and pel of figure layer.The content of design document be by a plurality of drawing elements as straight line, circle, word etc. form, and are called for short pel.Figure layer is an attribute of pel, and the pel of phase diagram layer has formed the subset one by one of drawing the inside.For a lot of operations of figure layer, as changed color, switch, control printing etc., pel onset that can be to all same figure layers, reaches the object to the batch operation of pel.Figure layer is collaborative to be referred to, the Team Member of different majors, carries out work at different figure layers, does not disturb each other; When coordinating between specialty, the application rule that needs a set of figure layer, in the time of such as the drawing of the use B specialty of A specialty, automatically change the color of some figure layer of B specialty drawing, automatically some figure layer closed and do not shown etc., thereby reach the object of cooperation.Figure layer is worked in coordination with often to be needed to be combined with external reference is collaborative, and can not realize with the inherent function of CAD software, needs by the specific software function module of exploitation.But figure layer is collaborative, than external reference is collaborative, more go deep into a step, the level of cooperation is darker.
External reference is worked in coordination with and schemed layer collaborative is all more effective Synergistic method in practice, still also has following problem:
The first, external reference is collaborative and figure layer is collaborative still thin not to the degree of task division.External reference is collaborative, and task division can only be take file as unit; Figure layer is collaborative, and task division can only Yi Tucengwei unit.Each file, each figure layer, all may comprise a large amount of design contents, and sometimes design objective involves different files, the modification of the design content of different figure layers.Some task just there will be the situation that a plurality of people of needs revise together like this, causes in design process the frequent collision conflict that occurs, the task that some originally can concurrent working becomes can only work in series.
The second, use external reference can bring a series of problem.These problems comprise: the drawing quantity that (1) submits to owner is very many, and being difficult for distinguishing which file is master file, is also very easy to cause missing documents.(2) between different majors because need cross-reference, may form complicated nested reference relation, sometimes also form circulation reference, as the drawing of A specialty with reference to B specialty, but this drawing of B specialty also needs the drawing with reference to A specialty conversely.Circulation, with reference to making the reference relation very complicated confusion that becomes, also makes software operation efficiency be a greater impact.(3) modification is very difficult.Because an engineering drawing has been divided into very many assignment files, will revise like this problem may involve and will revise a plurality of files, when revising, also to keep the consistance of coordinate, designer need to repeatedly be switched in the middle of different working documents like this, has reduced on the contrary to a certain extent design efficiency.
The 3rd, figure layer is worked in coordination with needs there is very strict cooperation rule between specialty, causes being difficult to carry out.Implement figure layer collaborative higher to the requirement of design team, between different majors, needing has strict figure layer standard, could process the efficiency that improves cooperation by certain robotization like this.
Summary of the invention

More excellent, after described first step, insert second step:
Described in the name of segment corresponding to the referenced pel that copies and the figure block name in described engineering drawing compare, check and have or not duplication of name;
If born the same name, the name of the segment that the referenced pel that copies described in modification is corresponding.
Optimum, after described second step, insert the third step:
Delete and in described referenced pel, there is external reference and with reference to the pel of alternative document.
Preferably, between described the 3rd step and the 4th step, insert fourth step: in described engineering drawing, determine the transformation parameter of the pel in described new Object, and the pel of described new Object is converted, revise the attribute of pel.
The invention also discloses a kind of engineering collaborative design system based on pel, it is characterized in that, comprising:

Preferably, described system also comprises: conversion module is used for determining at described engineering drawing the transformation parameter of the pel in described new Object, and the pel of described new Object is converted, and revises the attribute of pel.
The present invention can produce following beneficial effect:
The first, the contradiction of the convenience that the collaborative design method based on pel can arrange one's duties better and the modularity of design.Pel is the least unit that forms drawing file, and which pel user, can select arbitrarily with reference to during with reference to the pel of other file a drawing file the inside, can be one, can be one group, can be also whole file.If the pel of the whole file of reference is just equivalent to external reference collaborative; If with reference to a picture group unit, just collaborative similar with figure layer, but the method for selection is collaborative abundant more than figure layer, such as: the pel of an appointed area can be selected, the pel of some common trait can be selected to have.The feature here, just comprises figure layer, but also can be primitive types, the further feature such as font type, absolute altitude.Like this, designer just need to not be for collaborative requirement, and the design document of oneself is divided and solves very carefully, can be still by custom in the past, relevant content be all placed in a drawing file, other specialty with reference to time select on demand the parameter of reference.
The second, the file of user interactions, can must be thinlessser Task-decomposing because of the needs of collaborative design, and cause quantity sharply to increase.Design module does not need excessive refinement, but still can be used to easily other members of team.The drawing quantity that consigns to like this owner just can roughly conform to actual job requirement.
The 3rd, between the design document of different majors, can be because of cross-reference, and form circulation reference relation.This is that other pel of these pel institute references is removed in meeting of the present invention because one or a picture group unit are when being referenced.With reference to these removed pels, can set up separately in addition reference relation if necessary.Therefore, the reference relation between pel is very simple, is all one deck reference.This is also to meet cooperation custom actual between specialty.
The 4th, it is relatively simple that revisions on drawings becomes: because there is no complicated nested adduction relationship, so need to not switch back and forth in reference to file a plurality of, at most only need to enter the pel of reference, switch once.And, revise pel and be equivalent to directly at current file, modify, outside with reference to quick, simple than revising.
The 5th, the threshold of application is lower, and not needing has strict cooperation regular between specialty.Between specialty, can select arbitrarily the pel in file each other to carry out reference.

Embodiment
In order to make object of the present invention, technical scheme, beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is described in further details.Should be appreciated that specific embodiment described herein, only for explaining the present invention, is not intended to limit the present invention.
Below in conjunction with the drawings and specific embodiments, realization of the present invention is described in detail:
The present invention is the automatic processing procedure of a computing machine, by recording the reference relation of the pel between engineering drawing, realizes after drawing change the synergy that other relevant drawing upgrades automatically.
The present invention can be applied in the Synergistic method that carries out engineering design based on AutoCAD, but method and the module used are not limited to AutoCAD platform, as long as other software platform can provide corresponding interface.
The process flow diagram of the engineering collaborative design method based on pel of the present invention as shown in Figure 1.The method comprises the steps:
The first step is determined the parameter that is referenced the parameter of drawing, the pel being referenced, new Object in engineering drawing.
In first step, need to confirm to be referenced the cutting parameter of pel, cutting parameter comprises: the scope of pel, the characteristic attribute of pel, reference and be referenced the specialty at file place.Characteristic attribute can comprise any one or the multiple attribute that is referenced pel, as: figure layer, font, line style, highly, live width, color etc.If set up detailed collaborative design rule between specialty, so the specialized information of record just can be in cutting process automatic application rule.
Second step, described engineering drawing by the described parameter that is referenced drawing be referenced drawing and establish the link, described in reading, be referenced the pel that is referenced in drawing, and according to the parameter of described new Object using the described pel being inserted into after pel is processed in described engineering drawing as new Object that is referenced.
In second step, the parameter of described engineering drawing by being referenced drawing with described in be referenced drawing and establish the link, described in reading, be referenced being referenced after pel in drawing, can insert first step: described in judgement, be referenced pel and whether exist in described engineering drawing; Described be referenced pel and existed in described engineering drawing in the situation that, a newly-built example that points to existing referenced pel in described engineering drawing; The described pel that is referenced in non-existent situation, copies described referenced pel in described engineering drawing.
The name of segment corresponding to the referenced pel copying and the figure block name in described engineering drawing are compared, check and have or not duplication of name; If born the same name, the name of the segment that the referenced pel that copies described in modification is corresponding.Delete and in described referenced pel, there is external reference and with reference to the pel of alternative document, avoid being absorbed in circulation reference, also simplified reference relation.
The 3rd step is determined the screening parameter of the pel of described new Object, and the pel of described new Object is screened in described engineering drawing, deletes nonconforming pel;
The 4th step, in described engineering drawing, record described new Object with reference to information.
Between described the 3rd step and the 4th step, can insert fourth step: the transformation parameter of determining the pel in described new Object in described engineering drawing, and the pel of described new Object is converted, revise the attribute of new Object pel, to meet actual design needs.
In described the 4th step, record the comprising with reference to information of pel of described new Object: be referenced file numbering, be referenced pel cutting parameter, be referenced the specialty at file place etc.These information, when the pel being referenced changes, can be used for the pel of described new Object to upgrade.
The 5th step, be referenced drawing described in revising after, according in described engineering drawing, record with reference to information, after the amended referenced pel reading is screened, be inserted in described engineering drawing, revise the reference relation of the pel upgrading in described engineering drawing, delete the pel before upgrading.
In described the 5th step, when the pel being referenced changes, obtain the reciprocal reference information of the new Object pel corresponding with being referenced pel, comprise, with reference to parameter, screening parameter, transformation parameter.In engineering drawing, revise the name of the segment that new Object pel is corresponding, avoid again copying and clashing.According in described engineering drawing, record with reference to information, the amended referenced pel reading is screened, is inserted in described engineering drawing after conversion process, revise the reference relation of the pel upgrading in described engineering drawing, delete the pel before upgrading.
Be the process flow diagram of setting up pel reference relation of the present invention as shown in Figure 2, every one-phase of this process be progressively described now:
(1) open engineering drawing;
(2) receive user's input message, determine the parameters of the drawing that needs reference.
Parameter comprises:
The drawing file unique ID numbering corresponding in system the inside that needs reference;
The segment title that needs reference, if do not had, with reference to all pels of whole file;
Newly-established reference object is in the insertion point of current file;
Newly-established reference object is in the insertion ratio of current file;
Newly-established reference object is at the rotary proportional of current file.
Segment, refers to the set that one group of Subgraph unit forms.After one picture group unit forms a segment, for their operation, just can take segment and copy and operate as unit carries out integral body, for CAD designs, provide a lot of facilities.A segment can occur repeatedly in an engineering drawing, and each position occurring, size, angle etc. can be different.Pel Synergistic method, when selecting pel, can be take whole file as unit, also can using one of them segment as unit.Here be only the object of selecting reference, below also can be further processed the object of reference.
(3) copy the relevant pel that is referenced file
Concrete step is:
The file being referenced is opened on backstage;
The related content of file reading, if with reference to specifying segment, read-only fetching is determined the pel of segment; If with reference to the pel of whole file, read the information of all pels;
The pel that is referenced of judgement in current file whether the form with segment exist; If there is no, directly copy relevant pel; If existed, only need a newly-built example that points to existing segment, but will be screening conditions, the conversion condition of input subsequently, and the merging of input before;
The content reading and current file are compared, check the segment that has or not duplication of name;
Segment to bearing the same name directly renames in the content reading, and avoids conflict;
From the content reading, outside reference with reference to the segment of other file pel, delete;
Reading of content after processing, is inserted into current file as segment.
(4) receive user's input message, determine the parameters that the pel of reference is screened and converted, comprising:
Screening parameter: the coordinate range of reference, primitive features: as figure layer, font, line style, live width etc.,
Transformation parameter: with reference to file and the specialty that is referenced file place, the figure layer transformation rule between specialty.
(5) pel copying is screened and converted, meet the needs that use.
The pel being referenced and current reality need to still have certain distance, need to process processing according to actual conditions.The processing here mainly comprises screening and conversion.
Screening refers to, according to certain condition, nonconforming pel is deleted.Modal screening conditions are coordinate ranges of reference.As a drawing of drawing a plurality of picture frames, when being referenced, often only need one of them picture frame.Secondly, screening conditions can be also graphic features arbitrarily, as: figure layer, font, line style, live width etc.As required, only retain satisfactory pel.Screening is one of maximum difference that pel is collaborative with external reference is worked in coordination with, figure layer is collaborative.Because the file being referenced is likely used by other people, so external reference and figure layer is collaborative, all cannot delete the pel in the file being referenced, other part can only be hidden.And pel collaborative be that pel is copied, so can accomplish screening, delete.This size for minimizing drawing file is, the dirigibility of increase reference is very beneficial.
Conversion refers to: the pel copying, according to certain rule, revise the attribute of pel.Conversion is the collaborative conventional method of figure layer, applicable too here.According to reference to file be referenced file place specialty, in conjunction with the figure layer rule between specialty, can implement with down conversion the pel of difference figure layer: ON/OFF figure layer, locking/unlocking figure layer, change a figure layer color, change the printable attribute of figure layer etc.In figure layer is collaborative, transformation rule can only be formulated for figure layer, because the least unit of cooperation is figure layer; And the least unit of the collaborative conversion of pel is pel itself, can accomplish meticulousr conversion, as: for primitive attributes such as font, line style, live width, height.
(6) block the reference relation of multilayer
Cooperation between specialty, mainly to cooperate between two, so drawing reference relation between them, only to need one-level reference in fact, if that is: A specialty need to be with reference to the figure of B specialty, and in this figure, B specialty is again with reference to C specialty, the content of C specialty, is otiose for A specialty so in fact.If A specialty needs really with reference to C specialty, can directly in the drawing of A specialty, set up again the reference to C specialty so, and need not rely on B specialty with reference to content.Externally, with reference in Synergistic method, due to the restriction of CAD software, the nested reference relation of this multilayer cannot be removed, and after having caused in reference between specialty repeatedly, it is very chaotic that relation becomes, and drawing is very complicated, easily makes mistakes.A more typical example is, A specialty and B specialty respectively have a drawing, and A is with reference to the partial content of B specialty here, and the reference of B specialty the other partial content of A specialty.Finally so just form circulation reference, brought confusion to CAD running software.In the collaborative method of pel, for this situation, process specially: when setting up reference, if the content of reference is also with reference to other file content, this part content is removed.Like this, no matter how reference between specialty is simple one deck reference relation between pel, as shown in Figure 5 all the time.
(7) record pel with reference to information, for automatic renewal is from now on prepared.
Record with reference to information, comprise all inputs of step 1 and three.Reason with reference to two step typings of unpack is that the parameter of step 3 need to could the mode by user interactions be inputted after pel copies on drawing, otherwise not directly perceived, inaccurate.
Be the process flow diagram flow chart of the pel that is referenced of renewal of the present invention as shown in Figure 3, every one-phase of this process be progressively described now:
(1) obtain the reciprocal reference information of the pel being referenced, comprising: with reference to parameter, screening parameter, transformation parameter;
(2) segment corresponding to the pel having existed, be referenced renamed, avoid again copying and clashing;
(3) fileinfo being referenced is read on backstage;
(4) according to being recorded in the parameter information in current file, the pel to the file being referenced reading out, screens, the processing such as conversion, and this processing is identical with step 3;
(5) pel after processing is copied to current file;
(6) revise the original segment with reference to old pel, make it point to new pel;
(7) delete old pel.
