• 下载Teigha SDK 21.6 .NET

1.概述

这段代码展示了如何使用 Teigha SDK 创建各种类型的 CAD 标注。主要包含以下几种标注类型：
⚡ 对齐标注 (AlignedDimension)
旋转标注 (RotatedDimension)
角度标注 - 两线 (LineAngularDimension2)
角度标注 - 三点 (Point3AngularDimension)
弧长标注 (ArcDimension)
↔️ 半径标注 (RadialDimension)
⭕ 直径标注 (DiametricDimension)
大型半径标注 (RadialDimensionLarge)
坐标标注 (OrdinateDimension)

2.基础设置 ️

2.1 创建数据库和事务

using (Database db = new Database(true, true))
{
    TransactionManager tm = db.TransactionManager;
    using (Transaction ta = tm.StartTransaction())
    {
        // 标注创建代码
        ta.Commit();
    }
}

2.2 创建线型 〰️

using (LinetypeTable lineTable = (LinetypeTable)db.LinetypeTableId.GetObject(OpenMode.ForWrite))
{
    LinetypeTableRecord ltr = new LinetypeTableRecord();
    ltr.Name = "TestLineType";
    lineTable.Add(ltr);
    ltr.PatternLength = 0.1;
    ltr.NumDashes = 9;
    ltr.SetDashLengthAt(0, 0.2);
    ltr.SetDashLengthAt(1, -0.2);
}

3. 创建标注 ✨

3.1 对齐标注示例

AlignedDimension alDim1 = new AlignedDimension(
    new Point3d(0, 0, 0),     // 第一点
    new Point3d(3, 1, 0),     // 第二点
    new Point3d(1, 2, 0),     // 标注线位置点
    null,                     // 标注文字
    db.Dimstyle              // 标注样式
);
btr.AppendEntity(alDim1);
alDim1.SetDatabaseDefaults();

3.2 常用标注属性设置 ⚙️

dimension.Dimtmove = 1;              // 文字位置移动规则
dimension.UsingDefaultTextPosition = false;  // 是否使用默认文字位置
dimension.TextPosition = new Point3d(2, 4, 0);  // 文字位置
dimension.DimensionText = "Distance is <> units";  // 标注文字
dimension.Dimtol = true;             // 启用公差
dimension.Dimtp = 0.02;              // 上公差
dimension.Dimtm = 0.02;              // 下公差
dimension.Dimgap = -0.2;             // 文字间隙
dimension.Dimclrd = Color.FromColorIndex(ColorMethod.ByAci, 1);  // 标注线颜色

4. 标注类型详解

4.1 旋转标注

与对齐标注类似，但可以指定旋转角度：

RotatedDimension rotDim = new RotatedDimension(
    -0.2,                    // 旋转角度
    new Point3d(7, 0, 0),    // 第一点
    new Point3d(10, 1, 0),   // 第二点
    new Point3d(8, 2, 0),    // 标注线位置点
    null,                    // 标注文字
    db.Dimstyle             // 标注样式
);

4.2 角度标注

LineAngularDimension2 angDim = new LineAngularDimension2(
    new Point3d(16, 0, 0),    // 第一线起点
    new Point3d(16.5, 1, 0),  // 第一线终点
    new Point3d(15, 0, 0),    // 第二线起点
    new Point3d(14.5, 1, 0),  // 第二线终点
    new Point3d(15.5, 2, 0),  // 标注弧线位置点
    null,                     // 标注文字
    db.Dimstyle              // 标注样式
);

4.3 半径标注 ↔️

RadialDimension radDim = new RadialDimension(
    new Point3d(37, 0, 0),    // 圆心点
    new Point3d(40, 1, 0),    // 圆周点
    1,                        // 引线长度
    null,                     // 标注文字
    db.Dimstyle              // 标注样式
);

5. 最佳实践

✅ 总是使用事务管理标注的创建和修改
调用 SetDatabaseDefaults() 设置默认值
使用 CopyFrom() 复制现有标注的属性
使用 TransformBy() 移动或变换标注
合理设置标注样式和文字位置

6. 注意事项 ⚠️

创建标注后需要将其添加到块表记录中
修改标注属性前确保获取了写权限
注意坐标点的正确性和顺序
合理处理标注文字的位置和样式
注意保存文件时使用正确的 DWG 版本

7. 进阶技巧

使用适当的命名空间

   using Teigha.Runtime;
   using Teigha.DatabaseServices;
   using Teigha.Geometry;

标注样式定制
文字样式
箭头样式
线型样式
尺寸样式
