Summary: The 2 dimension figure that introduced to be generated with UG-drafting is changed into a kind of of DXF file format reliable method, solved complex because parameter is installed,constructional 2 dimension graph is changed directly with UGTODXF undeserved and the disappear hidden from view that bring and view are missing wait for a problem, realized UG2 dimension graph and software of 2 dimension CAD without seam changeover. Keyword: UG; DXF; Data changeover; The Unigaphics that company of UGS of United States of preface of 2 dimension graph develops (UG) software is CAD/CAM/CAE of a collect the large CAD software at an organic whole. Thirdly compound modelling, feature establishs safeguard model, assemble build a model, assemble clearance and interference examination, orgnaization athletic analysis and structure are limited yuan of analysis function is powerful, add its to be in the CAM of lead position on the technology, make products plan, analysis and treatment are finished, those who realized CAD/CAM/CAE is organic and compositive. At present UG software already made the times CAD software that gets an user to look at in person, if treatment facilities is advanced, can come true completely to turn production without the graph. But with respect to Chinese user, because make equipment still do not have complete modernization at present, the production business of true CAD/CAM unifinication is not much, accordingly, the 2 dimension that still need component in product production process design blueprint. But software of any a kind of CAD are not perfect, the Drafting module of UG is tagged in Chinese character input, symbol and respect of list work out from there still is the place that fare badly for convenient sex. Use the UG of 14 version, although have module of Chinese character input, but not as ideal as Windows compatibility, do not have other to word processing software of 2 dimension CAD (like AUTOCAD) convenient, to complex assembly drawing form need uses more time composition word processing to work. Regard a CAD application as the unit, always make full use of the good qualities of software of every kinds of CAD, it is especially below the state of affairs with UG less a cycle of songs in a traditional opera, build the good qualities of model, analysis and treatment to fill those who distribute brandish UG, often turn the word processing of 2 dimension graph to AUTOCAD to undertake. Accordingly, the user often should use UG and AUTOCAD changeover function. To make sure data is shared, UG-Translator offerred a variety of software interface technologies. Among them the direct changeover interface that UGTODXF is UG and AUTOCAD. Of 1 problem putting forward UG is a large-scale CAD/CAM/CAE software, its data set is become degree tall. Its are three-dimensional model, assemble and information of 2 dimension blueprint is centrally in file of a Part, and other CAD software (be like SolidWorks, solidedge) it is the model, assemble and information of 2 dimension graph is deposited respectively in different file. Accordingly, when the UGTODXF that using UG-Translator undertakes data is changed, must distinguish the of all kinds information in Part file, undertake data accepts or reject. If want to change the figure in UG-Drafting in AUTOCAD to undertake word processing, advocate if be opposite,secondly dimension information has transition. The content that its change basically is view (include umbriferous view, local enlarge graph, cutaway view and wait to view) dimension, form the concerned information such as tolerancepublic errand and character. Accordingly, when the UGTODXF that using UG-Translator undertakes data format is changed, the concerned parameter that must change a project to control undertakes installing. However, to complex assembly drawing form, want to obtain the DXF document that agrees completely with original figure, implementation rises more complex. Often install because of parameter undeserved and make redundant line, appear even sometimes view and thalweg are missing wait for a problem. When 2 changeover method is using UGTODXF to change complex assembly drawing form, install to because concern parameter,avoid undeserved and cause redundant line and view to lose wait for a problem, in transition, use CGM data form excessive. CGM (Computer Graphics Mefafile) is format of standard of graph of a of ANSI 2 dimension. CGM transition is complete according to current figure window medium indication outline and graph make CGM file, this file can issue transplanting in different operating system. UG uses binary encode to output CGM. After making CGM file, found a new document again, introduce the CGM file that makes before (Import) . Next reoccupy UG TODXF outputs DXF file format. The DXF file that such generating is opened in AUTOCAD agree completely with UG-Drafting graph, nonexistent generation is redundant line and view are missing wait for a problem. The process that makes DXF file in UG divides a pace: The first pace is to specify parameter level interactively, the 2nd pace is changeover phase. After changeover, AUTOCAD wants can complete open the DXF file that makes by UG-Translator, still must to load file of two font form, they are Ugtxt respectively. Shp and Ugmtxt.
Shp. The measure in file of form of font of the to load in AUTOCAD is: 1) copy Ugtxt from inside the EDS140/ugtodxf/ catalog of UG.
Shp and Ugmtxt.
Two files go to Shp in the Font folder in AUTOCAD. 2) Ugtxt is compiled with Compile command in AUTOCAD.
Shp and Ugmtxt.
Shp, open the DXF file that makes by UG next. Be as follows UG-Drafting without the concrete step that seams changeover to become DXF document: (1) is in UG, open the component that wants changeover, enter Drafting, the choice wants the blueprint name of changeover. (2) chooses File-Export-CGM, appear at this moment the dialog box that inputs CGM file name, requirement user designates name of a file, input file name Filename (patulous name need not be inputted, the system can be added automatically) hind, again OK. (3) appears at this moment dialog box, preexistence uses Fit in graphical window, believe firmly the content that wants changeover appears in graphical window entirely; In installing a dialog box by right graph again each option, next OK, made CGM file so. (4) chooses File-New to build Newname of a file. (5) appears at this moment in File-import-CGM (6) of the choice in new document dialog box of choice CGM file. Choose the CGM file that builds before, and OK, the CGM file that makes before at this moment is introduced in current file. (7) chooses File-Export-DXF, occurrence dialog box. Designate DXF file name, default is the name that builds a file, its expand the name is DXF. Click Class Select to press again twist, choose all content in graphical window. The other option in the dialog box can press default, choose OK next, made DXF file so. (the DXF file copy that 8) will make has AUTOCAD or other to installation on the computer of software of 2 dimension CAD, run AUTOCAD again, open the DXF file that makes on UG with DXF means, you can see the graphical just the same in the graph that open and UG-Drafting, missing without any picture news. 3 last words are opposite complex when assembling a graph to undertake DXF is changed, through using CGM data form excessive, the geometrical outline that in outputting UG-Drafting only, shows (be like view, dimension, form tolerancepublic errand and about tag etc) , both neither can increase line to also won't lose view, assured the DXF file that opens in AUTOCAD thereby, its graph shows agree completely with UG-Drafting.
