关于AutoCAD二次开发导出图纸为PDF格式
作为一个刚刚接触AutoCAD二次开发的小白来说，一切都是新鲜的，好像发现新大陆，打开了新的学习大门，越来越感兴趣，同时也深知学无止境，所以努力学习、努力成长。
本次主要写的是关于AutoCAD二次开发的基础文档，目的有两个：1、从基础的学习开始，把学到的或者看到的好东西分享一下。2、记录一下AutoCAD二次开发的过程。也许以后的某一天，回头一看，能够形成一个简单的并且实际应用的体系，初衷如此。
首先引入引用和参考：
1 using Autodesk.AutoCAD.Runtime; 2 using Autodesk.AutoCAD.ApplicationServices; 3 using Autodesk.AutoCAD.DatabaseServices; 4 using Autodesk.AutoCAD.Colors; 5 using Autodesk.AutoCAD.Ribbon; 6 using acadApp = Autodesk.AutoCAD.ApplicationServices.Application; 7 using Autodesk.Windows; 8 using System; 9 using System.Collections; 10 using System.Collections.Specialized; 11 using Autodesk.AutoCAD.EditorInput; 12 using Autodesk.AutoCAD.Interop; 13 using Autodesk.AutoCAD.Interop.Common; 14 using Microsoft.VisualBasic; 15
然后编写命令代码：
1 18 [CommandMethod("dwg2PDF",CommandFlags.Session)] 2 19 public static void dwg2PDF() 3 20 { 4 21 5 22 Document activeDoc = Application.DocumentManager.MdiActiveDocument; 6 23 AcadDocument ThisDrawing = (AcadDocument) activeDoc.GetAcadDocument(); 7 24 8 25 AcadLayout layout = ThisDrawing.ActiveLayout; 9 26 10 27 String MediaName = layout.CanonicalMediaName; 11 28 if (MediaName.Equals("")) 12 29 { 13 30 activeDoc.Editor.WriteMessage("There is no media set for the active layout."); 14 31 return; 15 32 } 16 33 else 17 34 { 18 35 activeDoc.Editor.WriteMessage("The media for the active layout is: " + MediaName); 19 36 } 20 37 21 38 //转换的主要内容 22 39 23 40 try 24 41 { 25 42 AcadPlotConfiguration oplot = ThisDrawing.PlotConfigurations.Add("PDF", layout.ModelType); 26 43 oplot.PaperUnits = AcPlotPaperUnits.acMillimeters; 27 44 oplot.StyleSheet = "monochrome.ctb"; 28 45 oplot.PlotWithPlotStyles = true; 29 46 oplot.ConfigName = "DWG To PDF.pc3"; 30 47 oplot.UseStandardScale = true; 31 48 oplot.StandardScale = AcPlotScale.acScaleToFit; 32 49 oplot.PlotType = AcPlotType.acExtents; 33 50 oplot.CenterPlot = true; 34 51 35 52 Object oMediaNames = layout.GetCanonicalMediaNames(); 36 53 37 54 ArrayList mediaNames = new ArrayList((string[])oMediaNames); 38 55 39 56 foreach (String sName in mediaNames) 40 57 { 41 58 if (sName.Contains(MediaName)) 42 59 { 43 60 oplot.CanonicalMediaName = sName; 44 61 layout.CopyFrom(oplot); 45 62 layout.PlotRotation = AcPlotRotation.ac0degrees; 46 63 layout.RefreshPlotDeviceInfo(); 47 64 48 65 ThisDrawing.SetVariable("BACKGROUNDPLOT", 0); 49 66 ThisDrawing.Plot.QuietErrorMode = true; 50 67 51 68 string pdfname = Interaction.InputBox("请输入保存文件名称！", "提示"); 52 69 53 70 ThisDrawing.Plot.PlotToFile("C:\\Users\\Administrator\\Desktop\\" + pdfname+ ".pdf", "DWG To PDF.pc3"); 54 71 oplot.Delete(); 55 72 oplot = null; 56 73 57 74 58 75 //保存并且关闭当前文档 59 76 object obj = Application.GetSystemVariable("DBMOD"); 60 77 Document acDoc = Application.DocumentManager.MdiActiveDocument; 61 78 // Check the value of DBMOD, if 0 then the drawing has no unsaved changes 62 79 if (System.Convert.ToInt16(obj) != 0) 63 80 { 64 81 acDoc.Database.SaveAs(acDoc.Name, true, DwgVersion.Current, 65 82 acDoc.Database.SecurityParameters); 66 83 acDoc.CloseAndSave(acDoc.Name); 67 84 } 68 85 return; 69 86 } 70 87 } 71 88 } 72 89 catch (System.Exception) 73 90 { 74 91 activeDoc .Editor.WriteMessage("\n程序出现硬性错误，请关闭后重新打开！"); 75 92 } 76 93 }
