1. 线性对齐标注 (AcDbAlignedDimension):

4. // 假设有两条线的端点定义了对齐方向
5. AcGePoint3d basePt, definingLineStart, definingLineEnd;
7. AcDbAlignedDimension *pAlignedDim = new AcDbAlignedDimension;
8. pAlignedDim->setDefiningLine(definingLineStart, definingLineEnd); // 设置定义线
9. pAlignedDim->setBasePoint(basePt); // 设置基准点
10. // 然后同线性标注一样设置关联实体、标注样式、文本位置等属性
11. // 并插入到块记录中

20. pRotatedDim->setLeaderEndPoint(leaderEndPoint); // 设置引线端点
21. pRotatedDim->setRotation(rotationAngle); // 设置旋转角度
22. // 同样设置关联实体、标注样式等属性，并插入到块记录中

35. AcGePoint3d arcMidPt, chordPt;
37. AcDbDiametricDimension *pDiametricDim = new AcDbDiametricDimension;
38. pDiametricDim->setArcMidPoint(arcMidPt); // 设置圆弧中点
39. pDiametricDim->setChordPoint(chordPt); // 设置通过圆弧的弦上的点
40. // 同样完成其他属性设置和插入操作
41. 两线角度标注 (AcDb2LineAngularDimension):
43. Cpp
44. AcGePoint3d line1Start, line1End, line2Start, line2End;
46. AcDb2LineAngularDimension *p2LineAngDim = new AcDb2LineAngularDimension;

49. p2LineAngDim->setLine2StartPoint(line2Start);
50. p2LineAngDim->setLine2EndPoint(line2End);
51. // 完成后续属性设置和插入
52. 三点角度标注 (AcDb3PointAngularDimension):
54. Cpp
55. AcGePoint3d pt1, pt2, pt3;
57. AcDb3PointAngularDimension *p3PointAngDim = new AcDb3PointAngularDimension;
58. p3PointAngDim->setPoint1(pt1);
59. p3PointAngDim->setPoint2(pt2);
60. p3PointAngDim->setPoint3(pt3);
61. // 其他属性设置和插入操作
62. 坐标标注 (AcDbOrdinateDimension):
64. Cpp
65. AcGePoint3d originPt, definedPt;
67. AcDbOrdinateDimension *pOrdinateDim = new AcDbOrdinateDimension;
68. pOrdinateDim->setOrigin(originPt); // 设置原点
69. pOrdinateDim->setDefinedPoint(definedPt); // 设置被定义点
70. // 指定坐标类型（X, Y 或 Z），以及其他属性设置和插入操作
