Embodiment
Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
The embodiment of the invention adopts multistage interrelational form that the engineering mark is directly or indirectly related with pel, and then when pel changed, the engineering mark of this pel can automatically be revised by system, does not need manual modification this project mark.Based on this, the embodiment of the invention provides the update method and the device of note sex object among a kind of CAD.Wherein CAD refers to graphics software, for example: each version of Auto CAD.
Embodiment 1
Present embodiment provides the update method of note sex object among a kind of CAD, and referring to Fig. 1, this method may further comprise the steps (S102-S104):
Step S102 sets up multistage relatedly for pel in the CAD drawing and note sex object, and wherein, the note sex object comprises size marking and engineering mark; This multistage association comprises pel and note direct correlation and/or indirect association, and directly or indirectly related between this note sex object; That is to say that first order association can be based upon on pel and the note sex object and (comprise size marking and engineering mark), also can be directly to be based upon (directly mark engineering mark object on size marking) between the note sex object.The above association in the second level normally is based upon between note sex object and the note sex object, promptly can mark the engineering mark on the size marking, also can dimensioning mark, and is same, also can dimensioning mark and engineering mark on the engineering mark.
Step S104 is when the pel in the CAD drawing takes place to upgrade, by the note sex object of above-mentioned multistage this pel of related update.
Clear in order to describe, represent pel 1 with A below, B represents the size marking of pel 1, and C represents the engineering mark of pel 1, and wherein, size marking and engineering mark can have a plurality of, for example B1, B2, perhaps C1, C2 etc.; Direct correlation and/or indirect association comprise one of following between the pel in the present embodiment and engineering mark:
First kind: pel and the direct correlation of one or more engineering mark; For example: A-C, perhaps A-C1, A-C2;
Second kind: pel is related with size marking, and size marking is related with the engineering mark; For example; A-B-C;
The third: pel has a plurality of engineering marks, and pel is related step by step with a plurality of engineering marks.For example: A-C1-C2;
The 4th kind: when pel has a plurality of size marking, that this pel is related step by step with a plurality of size markings; For example: A-B1-B2;
The 5th kind: be used for pel and size marking direct correlation, for example:; A-B.
Based on above-mentioned incidence relation, the note sex object by above-mentioned multistage related update pel can have following several implementation,
Mode one:
Search note sex object with figure element; When finding one or more engineerings mark (first kind of incidence relation), upgrade one by one and the engineering of this figure element marks directly with figure element.
Mode two:
Search note sex object with figure element; When finding pel and size marking direct correlation, upgrade this size marking; Search the note sex object related with this size marking; When finding size marking and engineering mark when related, upgrade this project and mark.The corresponding above-mentioned second kind of incidence relation of this mode.
Mode three:
Search note sex object with figure element; When finding pel when related step by step with a plurality of engineerings mark (the third incidence relation), the engineering of upgrading step by step with figure element marks.
For back two kinds of incidence relations, can adopt mode same as the prior art to upgrade, no longer describe in detail here.
In addition, above-mentioned which kind of incidence relation no matter, the note sex object by multistage related update pel all can adopt following manner to realize: search the first order note sex object with above-mentioned figure element, revise first order note sex object according to the update content of pel; Search and second level note sex object that renewal is related with first order note sex object, and the like, upgrade until the note sex object of finishing above-mentioned multistage association.
Present embodiment is in having used the CAD drafting system of note sex object and relevant figure element, system sets up the multistage related system of note sex object and relevant pel automatically, realized the note sex object, especially the engineering mark is with the automatic renewal of relevant pel variation, solved the mark of engineering in the relevant cad technique and can't realize the problem upgraded automatically with pel, improve the intelligent and ease for use of software, improved the efficient and the accuracy of drafting and revisions on drawings simultaneously.
Introduce the update method of note sex object among the CAD below in detail, this method begins to be introduced from drawing network element, comprises four parts substantially: draw relevant pel, set up the note sex object on relevant pel, revise relevant pel, the note sex object upgrades automatically.Referring to process flow diagram shown in Figure 2, this method may further comprise the steps:
Step S202 draws pel.
Step S204 draws the note sex object, and system sets up the incidence relation (being above-mentioned multistage related) between note sex object and the related object automatically.Present embodiment can be kept at this incidence relation in the graphic data base, and this incidence relation as above no longer describes in detail here.
Step S206 revises relevant pel.
Step S208 upgrades the note sex object automatically according to incidence relation.For example: system set up when creating note its with the modification pel between incidence relation, the traversal graphic data base, judge whether current note sex object is associated with the modification pel, find out and revise the first order note sex object that pel is associated, according to the new geometric position information of this pel, upgrade position, form and the content of first order note sex object automatically; Search and revise the second level note sex object that pel is associated then, upgrade position, form and the content of this second level note sex object automatically; By that analogy, under the current note sex object that finds, there is not related note sex object.
Present embodiment realizes that by setting up the multistage incidence relation between the relevant pel with it of note sex object the note sex object can upgrade position, form and the content of self automatically when relevant pel occurrence positions or change of shape.This technology has been set up the complete related system of note sex object with relevant pel, makes to comprise that size marking can both keep related with relevant pel with the engineering mark by all note sex objects.And support the multistage association of note sex object, for example size of mark on curve marks a base symbol then dimensionally, and when curve changed, at first size changed thereupon, and base symbol is according to the variation respective change of size then.Be the drafting pel referring to CAXA electronics chart board note sex object with relevant figure element example: Fig. 3, Fig. 4 promptly draws the note sex object (wherein, for mark pel relative dimensions
Be size marking, all the other are the engineering mark), Fig. 5 revises the result for the pel of expection, and Fig. 6 is the result that size is upgraded automatically.
The above-mentioned incidence relation of present embodiment by setting up, make the note sex object can keep concerning with the position of its relevant pel, and adjust self notes content according to the current state of affiliated partner in good time, promote the intelligent and ease for use of software, improved the efficient and the drawing accuracy of revisions on drawings.
