Converting AutoCAD Drawings to PDF


//////////////////////////////////////////////////////////////////////////////////////////////////// // This example was designed for using in Delphi 7 or higher. // // 1. Autodesk AutoCAD 2000 or above should be installed and activated on your PC. // Autodesk AutoCAD LT does not have COM interface and cannot be used as COM-server! // // 2. Universal Document Converter 5.2 or above should be installed, too. // // 3. Add "Universal Document Converter Type Library" and "AutoCAD XXXX Type Library" type libraries to the project. // XXXX is the AutoCAD version installed on your computer. // // Delphi 7: // Use the Project | Import Type Library menu. // Delphi 2006 or latter: // Use the Component | Import Component menu. // // Clear the "Generate Component Wrapper" checkbox and click the "Create Unit" button (Delphi 7) or // select the "Create Unit" option (Delphi 2006 or latter). // //////////////////////////////////////////////////////////////////////////////////////////////////// program AutoCADtoPDF; {$APPTYPE CONSOLE} uses SysUtils, Variants, Windows, Dialogs, ActiveX, UDC_TLB, AXDBLib_TLB, AutoCAD_TLB; procedure PrintAutoCADtoPDF(AutoCADFilePath: string); var objUDC: IUDC; Printer: IUDCPrinter; Profile: IProfile; App: AcadApplication; Doc: AcadDocument; Layout: AcadLayout; Version: Double; FormatSettings: TFormatSettings; ReadOnly, Password: OleVariant; nBACKGROUNDPLOT, nFILEDIA, nCMDDIA: OleVariant; xNull: OleVariant; SaveChanges: OleVariant; begin //Create a UDC object and get its interfaces objUDC := CoAPIWrapper.Create; Printer := objUDC.get_Printers('Universal Document Converter'); Profile := Printer.Profile; //Use Universal Document Converter API to change settings of converterd drawing Profile.Load('C:\Program Files\Universal Document Converter\UDC Profiles\Drawing to PDF.xml'); Profile.OutputLocation.Mode := LM_PREDEFINED; Profile.OutputLocation.FolderPath := 'c:\UDC Output Files'; Profile.PostProcessing.Mode := PP_OPEN_FOLDER; App := CoAcadApplication.Create; //double Version = double.Parse(App.Version.Substring(0, 4), new CultureInfo("en-US")); GetLocaleFormatSettings($0409 {en_US}, FormatSettings); Version := StrToFloat(Copy(App.Version, 1, 4), FormatSettings); //Open drawing from file ReadOnly := False; Password := Variants.EmptyParam; Doc := App.Documents.Open(AutoCADFilePath, ReadOnly, Password); //Change AutoCAD preferences for scaling the drawing to page if Doc.ActiveSpace = acPaperSpace then Layout := Doc.PaperSpace.Layout else //Doc.ActiveSpace = acModelSpace Layout := Doc.ModelSpace.Layout; Layout.PlotType := acExtents; Layout.UseStandardScale := True; Layout.StandardScale := acScaleToFit; Layout.CenterPlot := True; nBACKGROUNDPLOT := 0; nFILEDIA := 0; nCMDDIA := 0; if Version >= 16.1 then begin nBACKGROUNDPLOT := Doc.GetVariable('BACKGROUNDPLOT'); nFILEDIA := Doc.GetVariable('FILEDIA'); nCMDDIA := Doc.GetVariable('CMDDIA'); xNull := 0; Doc.SetVariable('BACKGROUNDPLOT', xNull); Doc.SetVariable('FILEDIA', xNull); Doc.SetVariable('CMDDIA', xNull); end; Doc.Plot.QuietErrorMode := True; //Plot the drawing Doc.Plot.PlotToDevice('Universal Document Converter'); if Version >= 16.1 then begin //Restore AutoCAD default preferences Doc.SetVariable('BACKGROUNDPLOT', nBACKGROUNDPLOT); Doc.SetVariable('FILEDIA', nFILEDIA); Doc.SetVariable('CMDDIA', nCMDDIA); end; //Close drawing SaveChanges := False; Doc.Close(SaveChanges, Variants.EmptyParam); //Close Autodesk AutoCAD App.Quit(); end; var TestFilePath: string; begin TestFilePath := ExtractFilePath(ParamStr(0)) + 'TestFile.dwg'; try CoInitialize(nil); try PrintAutoCADtoPDF(TestFilePath); finally CoUninitialize; end; except on E: Exception do MessageDlg(E.ClassName + ' : ' + E.Message, mtError, [mbOK], 0); end; end.
