Embodiment
A kind of girder construction part is published picture and the drawing optimization method fast, and its step is as follows:
(1) the three-dimensional Variant Design of girder construction part is set up the three-dimensional Variant Design master cast and the engineering drawing master module of girder construction part, and exploitation Variant Design program is carried out the three-dimensional Variant Design of girder construction part; Adopt modular technology and product family's technology, product type selecting in conjunction with enterprise, rationally divide module according to product function, analyze the parametrization modification relation of each module, determine reasonably to become ginseng, modification space, adopt SolidWorks2010, based on the template maximization principle, set up the three-dimensional Variant Design master cast and the engineering drawing master module of girder construction part, utilize VisualBasic6.0 that SolidWorks2010 is carried out secondary development, the modification situation exploitation Variant Design program of the design feature of bondbeam structural member and product, the three-dimensional Variant Design of realization girder construction part.
(2) the quick generation of girder construction part two-dimensional engineering graphic paper, utilize the association of design data between product model and the engineering drawing, generate girder construction part two-dimensional engineering graphic paper fast, by in model of parts, adding Custom Attributes, in the engineering drawing master module, add the attribute link, utilize the association of design data between product model and the engineering drawing, can generate girder construction part two-dimensional engineering graphic paper fast;
(3) generation of girder construction part engineering drawing message file adopts the method for view traversal to extract engineering drawing information automatically by program, and the information of being extracted comprises: view position, view size, scale of view, note position;
(4) drawing optimization, by generating the engineering drawing message file of girder construction part two-dimensional engineering graphic paper, exploitation drawing optimizer, girder construction part two-dimensional engineering graphic paper to quick generation is optimized, and described drawing optimization comprises view layout optimization, explains layout optimization, size layout optimization, view rupture automatically, the automatic generation of product information table, drawing format conversion;
View layout is optimized, and at first, calculates correct scale of view value and view position coordinates; Then, api interface function S caleRatio, the Position that utilizes SolidWorks2010 and provided is provided with again to scale of view and view position respectively; Correct scale of view size is that the situation of change by view size before and after the scale of view value that writes down in the engineering drawing message file and the Variant Design is determined; Correct view position coordinates is determined by the view centre coordinate that is write down in the engineering drawing message file.
Explain layout optimization, at first, the note positional information that is write down in the engineering drawing message file is changed and calculated, in the hope of correct note position coordinates; Then, utilize api function SetTextPoint to be provided with again to explaining the position.
The size layout optimization is that the boundary line can be divided into the size on the view inside dimension and external dimensions with the outermost sideline of view, and the distribution character of inside dimension and external dimensions is different, and their layout optimization method is also different, adopts an obligatory point method and a figure layer method respectively.
Near obligatory point method: at first, this inside dimension, draw a sketch point, and it is located fully by adding the constraint geometric relationship with this inside dimension graph of a correspondence key element; Then, the title and the inside dimension names associate of this sketch point are got up, and with its relevant information records in the engineering drawing message file; At last, when the size layout optimization, the method by traversal finds this sketch point, and inside dimension to correspondence is composed in the position of sketch point.Because this sketch point is located fully, it is with respect to the same moved further of graphical element, so, after the optimization this inside dimension also with the same moved further of graphical element.
A figure layer method: according to the level of view external dimensions, the outermost sideline of view is set at 0 layer, the figure level number outwards increases progressively, inwardly successively decreases.Like this, all external dimensions all will be referred to different figure layers, by the just distribution of energy controlling dimension of distance between the different figure layers is set.
View ruptures automatically, and the girder construction part mostly is slim-lined construction, in order clearly to represent the detailed information in the view, often need rupture to view.If adopt the method for in the engineering drawing master module, manually inserting fracture line to carry out the view fracture, can not guarantee after the Variant Design that the fracture line position changes synchronously with respect to model boundary, this does not meet the drawing standard of country and enterprise.So should write corresponding program view is ruptured automatically, its process is as follows: at first, calculate position breaklinePosition1, the breaklinePosition2 of fracture line; Then, utilize api function InsertBreak on the position of calculating gained, to insert fracture line; At last, utilize api function BreakView to carry out the view fracture automatically.
Product information table generates automatically, and the girder construction part is welded by sheet material, section bar usually, and the formulation that the automatic generation of product information table can be raw-material buying of girder construction part and processing technology provides foundation.Its concrete steps are as follows: at first, in model of parts, add part sequence number, part name, part specifications, weight, material, drafting person, draw Custom Attributes such as date, director's design, examination, technology examination, standardization examination, approval, audit, countersign, the total area, non-bevel line of cut length, bevel line of cut length, groove type, remarks, and the Custom Attributes value that changes is associated with model attributes; Then, the development information statistical program calculates and adds up the Custom Attributes value of parts; At last, the result who calculates gained is outputed in the product information table with the desired form of enterprise.
The drawing format conversion, in order to save the software overhead of enterprise, promote the circulation of drawing in enterprise, after the optimization of girder construction part two-dimensional engineering graphic paper finishes, can use api function SaveAs2 to convert engineering drawing in .DWG .GIF, four kinds of forms of .PDF .EDRW any one or a few.
(5) generate the girder construction part two-dimensional engineering graphic paper that meets country and company standard.
