AutoCAD 二次开发时，可以使用 TypeOf 来检查对象是否为特定的 AutoCAD 对象类型，以决定下一步操作。AutoCAD ActiveX 支持的对象类型非常多，涵盖了 AutoCAD 中几乎所有的实体和组件。以下列举一些常见的 AutoCAD 对象类型：

一、基础对象类型：

AcadBlockReference：块参照（Block Reference）

AcadDimension：标注（Dimension）

AcadHatch：填充（Hatch）

AcadLayer：图层（Layer）

AcadLine：直线（Line）

AcadMLine：多线（Multiline）

AcadPoint：点（Point）

AcadPolyline：二维多段线（2D Polyline）

Acad3DPolyline：三维多段线（3D Polyline）

AcadCircle：圆（Circle）

AcadArc：圆弧（Arc）

AcadEllipse：椭圆（Ellipse）

AcadText：文本（Text）

AcadInsert：插入（Insert）

AcadRay：射线（Ray）

AcadXLine：构造线（Xline）

AcadSpline：样条曲线（Spline）

二、高级对象类型：

AcadBlockTable：块表（Block Table）

AcadBlockTableRecord：块表记录（Block Table Record）

AcadDictionary：字典（Dictionary）

AcadDictionaryEntry：字典条目（Dictionary Entry）

AcadLayout：布局（Layout）

AcadObjectId：对象ID（Object ID）

AcadObject：基础对象（Generic Object）

AcadSelectionSet：选择集（Selection Set）

AcadTransaction：事务（Transaction）

三、集合和数组：

AcadObjectIdArray：对象ID数组

AcadObjectArray：对象数组

AcadBlockTableRecordIterator：块表记录迭代器

四、其他：

AcadDatabase：数据库（Database）

AcadDocument：文档（Document）

AcadApplication：应用程序（Application）

AcadUtility：实用工具（Utility）

随着 AutoCAD 的升级，对象类型可能会被添加，而旧的对象类型则可能会被弃用或替换。因此，需要关注当前版本 AutoCAD 的官方文档或帮助文件。

使用TypeOf时，须确保正在操作的对象是所期望的类型，否则可能会遇到运行时错误。如果不能确定对象的类型，则可以先使用 TypeOf 来检查一下它是否属于一个更通用的类型（如AcadObject），然后再进一步细化检查。
