7.1) when requiring picture frame inside dimension value to be equal to picture frame outside dimension value, input formula " %{a|V} ".Wherein " a " is the dimension name of the outer corresponding size of picture frame; V is the acronym of the English name " variables " of " argument table ", and herein for extract variable functor from argument table, the implication of full formula is: be imparted in prefix text box by the value of variable in argument table " a ";
7.2) when requiring picture frame inside dimension value to retain 0 decimal, input formula " %{a/ 0|V} ", wherein " a " is the dimension name of the outer corresponding size of picture frame; @is for retaining scale functor; V is for extracting variable functor, the implication of full formula is: be imparted in prefix text box after reservation 0 decimal that the value of variable in argument table " a " rounded up, in like manner, 1(or 2 is retained ...) position time, only need make " 0 " after "@" in formula into 1(or 2 ...);
7.3) when requiring picture frame inside dimension to be obtained through more complicated mapping relations by picture frame outside dimension, can realize by argument table, in prefix, now input formula " %{a|V} ", wherein " a " is the user-defined name variable in argument table, and it is obtained through other mapping relations of establishment by the size outside picture frame; V is for extracting variable functor, and the implication of full formula is: be imparted in prefix text box by User Defined in argument table, the value of variable " a " that obtains through complex mapping relation;
8) click " select-enabling prefix " for one, allow the step that prefix shows;
9) click " being applicable to " order for one, make element, step that drawing border, background are applicable to active view;
10) click " preservation " order for one, preserve the step of engineering drawing.
In step 3), described size marking comprises distance, angle, chamfering etc.
The present invention is applicable to that view segment in drawing is about the same, moulded dimension changes greatly, structure changes little Product Parametric Design.The present invention is in Solid Edge, creates the engineering drawing be linked with parameterized model, makes each view by company standard.Express except the segment of view except (needing to print) in picture frame, picture frame outer (without the need to printing) also needs complementary view.By the view " do dead " in picture frame, also " convert 2D view to " by the view in picture frame, this associates broken away views and model, and model becomes joins rear view and will change no longer thereupon.And the complementary view outside picture frame keeps " activity ", real-time and model keeps dynamically associating.In picture frame, the dimensional data of segment is by the link of editor's formula, keeps dynamically associating with the complementary view outside picture frame, thus ensure that dynamically associating of drawing in picture frame and three-dimensional model.So, play rambling view and be placed on picture frame because becoming reference and do not print outward, segment lines, mark, welding etc. that picture frame domestic demand prints keep maintaining static, ensure the neat and artistic, in good order of drawing interface, dimensional data also can keep real-time update simultaneously, ensure that the correctness that view is expressed.
The present invention is based on Solid Edge three-dimensional software, can be used for the exploitation of Product Parametric Design engineering drawing, ensure accuracy of gauge, avoid the variation becoming ginseng rear view segment, make engineering drawing interface can't be subject to the impact of Parameters variation and become disorderly and unsystematic simultaneously, but remain neat and artistic, in good order.The present invention is in Solid Edge engineering drawing, easy positioning, the view of easily makeing mistakes are moved to outside picture frame, corresponding fixing, correct view segment is created in picture frame, allow the view dimensions in picture frame and the view dimensions outside picture frame keep dynamically associating, the view dimensions outside picture frame and three-dimensional model keep dynamically associating.The potential risk that the method can avoid parametrization to bring, allowing parametrization play sharpest edges, being also significant simultaneously to developing the drawing meeting company standard.
The invention has the advantages that to avoid and become engineering drawing size break link and the positioning of view and the variation of segment after ginseng, ensure that the correctness of parametrization engineering drawing and the neat and artistic, in good order of drawing interface, eliminate the repetition and loaded down with trivial details work that adjust view after becoming ginseng simultaneously, the rapid Design that can realize disparity items is published picture, reach the effect that standardization, universalization, robotization are integrated, drastically increase design efficiency, allow Parametric designing play maximum advantage.

2) picture frame internal view is converted into 2D view, broken away views associates with three-dimensional model.Conventional project figure, after renewal is changed, can become disorderly and unsystematic mostly, for avoiding the generation of this phenomenon, the view that picture frame domestic demand prints should be converted into 2D view, disconnect its associating with three-dimensional model.
3) add auxiliary view outward and dimensioning at picture frame, itself and three-dimensional model have and dynamically associate.This step is transferred to can become rambling view outside the picture frame that do not need to print, and dimensioning etc., sets up dynamically associating of itself and three-dimensional model.
4) with formula the view dimensions in picture frame created with the view dimensions outside picture frame and associate.By demand editor formula, the view inside and outside picture frame is associated, reach the object of " three-dimensional model drives picture frame external view, picture frame external view to drive picture frame internal view ".
The enforcement of the inventive method mainly comprises the following steps:
1) one makes two-dimensional engineering graphic by design specifications by parameterized model, and makes the step of view by company standard.
2) one converts segment in picture frame to 2D view and the step of the adjustment such as Delete superfluous lines, profile drawing line view.
3) one is carried out the step of size marking to segment in picture frame, as shown in Figure 2.
4) converted the segment of 2D view in a corresponding picture frame to, created at picture frame the step that corresponding and model keeps the complementary view dynamically associated outward.
5) one is carried out the step of size marking to the view outside picture frame, as shown in Figure 3.
6) click the size of picture frame internal view for one, its Dimension Types is made into the step of " blank ".
7) click " selection-prefix " for one, in prefix text box, input the step of formula.In this example, require that picture frame inside dimension value is equal to picture frame outside dimension value, therefore, the formula of required input is " %{a|V} ".
