(完整版)Teigha使用说明

1、1、Teigha中DWG数据库结构:3.02及以下版本命名空间应将Teigha换为DWGdirect。O.nD no.nq. n| u_nV ewporl ISbK RotoidUC3R&c ortiRocotdEHork r劉 RftCOrtlCEiGCt经 常用到 的有 TextStyleTable、LayerTable、LinetypeTable、BlockTable 及其对应的TextStyleTableRecord、LayerTableRecord、LinetypeTableRecord、BlockTableRecord 及 Entity。2、具体使用2.1添加引用使用前应该添加 T

2、D_Mgd_3.03_9.dll或是其他版本类库，类库分为64位与32位，32位类库在64位系统上运行效果可能不太好。3.02版本及一下版本可能没有64位的类库。命名空间有：Teigha.DatabaseServices;Teigha.Geometry;Teigha.Colors;Teigha.Export_Import;Teigha.GraphicsI nterface;Teigha.GraphicsSystem;Teigha.Ru ntime;2.2 打开、新建、保存数据库使用之前应加上这个：using ( Services ser = new Services ()/ 一个应用程序加上一

3、个就行了，否则出错1、打开数据库( dwg 文件)using ( Database pDb = new Database( false , false )/ 不加参数会出错 pDb.ReadDwgFile( Application .StartupPath + TABMENU.dwg, FileOpenMode.OpenForReadAndWriteNoShare, false , );2、新建数据库using ( Database pDb = new Database()/ 加参数出错3、保存(1) 保存格式SaveType pSavetype = SaveTypeSave12; Save1

4、2 为.dwg Save13 为dxf 默认保存为 dwg ，可以不用指定。(2) 保存版本类型DwgVersion dwgver = DwgVersion.vAC18; /ACAD2010为 vAC24； ACAD200为 vAC21； ACAD200为 vAC18；很重要，保存时要用，版本过高时低版本 AutoCAD 不能打开。(3) 保存pDb.SaveAs(filename, dwgver);pDb 为数据库( Database)， filename 为 dwg 文件名， dwgver 为版本。2.3 写数据2.3.1 添加文本样式ObjectId styleId = ObjectId

5、 .Null;using ( TextStyleTable pStyles =( TextStyleTable )pDb.TextStyleTableId.GetObject( OpenMod.eForWrite)/ 文本样式记录using ( TextStyleTableRecord pStyle = new TextStyleTableRecord ()/ 表对象(记录)添加到表之前必须命名/ isShapeFile flag must also be set (if true) before adding the object/ to the database.pStyle.Name =

6、 styleName;/ 必须设定pStyle.IsShapeFile = isShapeFile;/ 添加(记录)到数据库之前必须设定(如果为 true )/ Add the object to the table. 添加对象(记录)到表 styleId = pStyles.Add(pStyle);/ 设置剩下的属性。 (可以添加后设置也可以添加之前设置) pStyle.TextSize = textSize;pStyle.XScale = xScale; pStyle.PriorSize = priorSize; pStyle.ObliquingAngle = obliquing; pSt

7、yle.FileName = fileName;if (isShapeFile) pStyle.PriorSize = 22.45;if (! string .IsNullOrEmpty(ttFaceName) pStyle.Font = newFontDescriptor (ttFaceName, bold, italic, charset, pitchAndFamily);return styleId;注： pDb 为 Database2.3.2 添加线型using ( LinetypeTable pLinetypes =( LinetypeTable )pDb.LinetypeTable

8、Id.GetObject( OpenMod.eForWrite)/ 线表记录using ( LinetypeTableRecord pLinetype = new LinetypeTableRecord () pLinetype.Name = name;/ 必须命名ObjectId linetypeId = pLinetypes.Add(pLinetype);/ 添加记录return linetypeId;注：线型要有相应的线型文件，且不一定能够加成功，线型可以在使用之前手动加在 dwg 模板中，从其他文件向 dwg 文件复制线型，可能不成功。2.3.3 添加块例：using ( BlockT

9、able blockTable = ( BlockTable )pDb.BlockTableId.GetObject( OpenMod.eForWrite)ObjectId annoBlockId;using ( BlockTableRecord btr = new BlockTableRecord ()btr.Name = AnnoBlock ;annoBlockId = blockTable.Add(btr);using ( Circle pCircle = new Circle ()pCircle.SetDatabaseDefaults(pDb);btr.AppendEntity(pCi

10、rcle);Point3d center = new Point3d (0, 0, 0);pCircle.Center = center;pCircle.Radius = 0.5;向块表中加入块之前， 块一定要有名字。 同时可以从其他文件中提取块， 加入到目标数据库 中 例：using ( Database db = new Database( false , false )if (! File .Exists( Application .StartupPath + BLOCKS + blockname +.dwg )MessageBoxShow(没找到 CAS块文件)；return Obje

11、ctId .Null;db.ReadDwgFile(Application .StartupPath + BLOCKS + blockname + .dwg ,FileOpenMode.OpenForReadAndAllShare, false , );using ( BlockTable pTable =( BlockTable )db.BlockTableId.Open( OpenMode.ForRead)using ( BlockTable bt =( BlockTable )pDb.BlockTableId.Open( OpenMod.eForWrite)using ( BlockTa

12、bleRecord btr = new BlockTableRecord ()foreach ( ObjectId id in pTable)using ( BlockTableRecord pBlock =( BlockTableRecord )id.Open( OpenMod.eForRead)foreach ( ObjectId entid in pBlock) using ( Entity pEnt =( Entity )entid.Open( OpenMod.eForRead, false , true )btr.AppendEntity( Entity )pEnt.Clone();

13、btr.Name = blockname;ObjectId blockid = bt.Add(btr);return blockid;234向模型(model)空间画实体(线、面等)加入线，例：using ( BlockTable blockTable = ( BlockTable )pDb.BlockTableId.GetObject( OpenMod.eForWrite) ObjectId modelSpaceID = blockTable BlockTableRecord .ModelSpace; using ( BlockTableRecord btr =( BlockTableRec

14、ord )modelSpaceID.GetObject( OpenMod.eForWrite)using ( Polyline2d pline = new Polyline2d () btr.AppendEntity(pline);/向块记录中添加线Vertex2d pVertex = new Vertex2d ();/ 顶点 Point3d pos = start;/ 起点pVertex = new Vertex2d (); pline.AppendVertex(pVertex);pos = start;/ pVertex.Position = pos; pVertex.Dispose();

15、起点pVertex = new Vertex2d (); pline.AppendVertex(pVertex); pos = end;/顶点，终点pVertex.Position = pos;if (linewidth = 0.0)pVertex.StartWidth = linewidth; / 线宽pVertex.EndWidth = linewidth;pVertex.Dispose();/pline.Closed = false;/ if (linestyle != null ) pline.Linetype = linestyle;/pline.Layer = LayerName;

16、/加入面的操作与上面加入线类似，但最后线的此属性在画线时不加， 但在成面时将属性变为 true线型图层名Closed 属性应设置成 true。插入文字：using ( BlockTableRecord bBTR =( BlockTableRecord )modelSpaceID.GetObject( OpenMod.eForWrite)using ( DBText pText = new DBText()/ 开始时插入文字以左上点为准插入using ( Database pDb = bBTR.Database) pText.SetDatabaseDefaults(pDb);ObjectId t

17、extId = bBTR.AppendEntity(pText);/ 注释pText.Annotative = AnnotativeStates .True;/ 加入到特殊群if (pGroup != null )pGroup.Append(textId);pText.Position = position; / 位置(应该是左上方) pText.AlignmentPoint = alignmentPoint;/ 校准点什么东西pText.Height = height;/ 高度pText.WidthFactor = 1.0; / 什么东西 pText.TextString = text;pT

18、ext.HorizontalMode = hMode;/ 文字模式pText.VerticalMode = vMode; / 垂直模式 pText.Oblique = OdaToRadian(oblique); / 倾斜 pText.Rotation = OdaToRadian(rotation);/ 旋转/ 文字样式if (!textstyleID.IsNull)pText.TextStyleId = textstyleID;/ 层名if (!layerId.IsNull)pText.SetLayerId(layerId, false );if (widthfactor != 0.0)pTe

19、xt.WidthFactor = widthfactor;/宽度因子插入块：using ( BlockTableRecord btr =( BlockTableRecord )modelSpaceID.GetObject( OpenMod.eForWrite)块在数据库中的 idBlockReference pBlkRef = new BlockReference (point, btr.ObjectId);/point 为插入的位置new Scale3d (scale, scale, scale);/图层id插入块比例pBlkRef.BlockTableRecord = BlockRefID

20、;/ pBlkRef.ScaleFactors = pBlkRef.LayerId = layerID;/ btr.AppendEntity(pBlkRef);/2.3.5 图层加入图层：using ( LayerTable pLayers = ( LayerTable )pDb.LayerTableId.GetObject( OpenMod.eForWrite) / 图层using ( LayerTableRecord pLayer = new LayerTableRecord () pLayer.Name = name; / 图层名必须有 pLayer.Color = Color .Fro

21、mColorIndex( ColorMethod .ByAci, color); / 颜色/ 图层线型 using ( LinetypeTable pLinetypes =( LinetypeTable )pDb.LinetypeTableId.GetObject( OpenMod.eForWrite)ObjectId linetypeId = pLinetypeslinetype; pLayer.LinetypeObjectId = linetypeId;return pLayers.Add(pLayer);/ObjectID2.4 关于视图在写完 dwg 文件之后， 打开 dwg 有时会找不到所画的实体， 因此在保存前应先定义好视图： 方法一：using ( ViewportTable vt =( ViewportTable )pDb.ViewportTableId.GetObject( OpenMod.eForWr
