问题：
现在想在CAD的特性表上添加自定义数据，用来显示数据和修改数据。
思路：
通过ObjectArx提供的工作手册，找到了 SheetSet 的说明（如图），但是没有找到示例。
不过也可以了解到是通过COM接口来实现。通过摸索，现在可以自定义添加基本类型的数据显示和修改了，将操作记录如下。
目前下拉列表如何添加还有待研究，后续会再更新。
解决：
1、准备工作：需要先生成GUID以备使用。
GUIDGEN.exe 可能存在路径：
“C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\Tools\guidgen.exe”
“D:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\guidgen.exe”
使用GUIDGEN.exe 生成两个UID供接口和属性类使用。
数值类型说明：（这里只说明几个常用类型，更多类型可详见：[url]https://docs.microsoft.com/zh-cn/dotnet/api/system.runtime.interopservices.varenum?view=net-6.0[/url]）
/*===================================================================
* VARTYPE 数据类型
*===================================================================*/
/*
* VT_I1 char
* VT_I2 short
* VT_I4 long
* VT_I8 64位整数
* VT_INT int
* VT_R4 float
* VT_R8 double
* VT_DATE 日期
* VT_BSTR 字符串类型
* VT_BYREF 引用
* VT_LPSTR 以 NULL 结尾的字符串
* VT_LPWSTR 由 null 终止的宽字符串
* VT_PTR 指针
* VT_VECTOR 简单的已计数数组
* VT_ARRAY SAFEARRAY 指针

::SysAllocString 进行cstring 到 bstr的转换
2、在Z_PIDDynamicProperty.h文件中添加定义：
在 Forward Declarations 添加接口IZ_pidEntityDynPropSitNumber定义：
// Forward Declarations
#ifndef __IZ_pidEntityDynPropSitNumber_FWD_DEFINED__
#define __IZ_pidEntityDynPropSitNumber_FWD_DEFINED__
typedef interface IZ_pidEntityDynPropSitNumber IZ_pidEntityDynPropSitNumber;
#endif /* __IZ_pidEntityDynPropSitNumber_FWD_DEFINED__ */

添加属性类Z_pidEntityDynPropSitNumber定义：
#ifndef __Z_pidEntityDynPropSitNumber_FWD_DEFINED__
#define __Z_pidEntityDynPropSitNumber_FWD_DEFINED__
#ifdef __cplusplus
typedef class Z_pidEntityDynPropSitNumber Z_pidEntityDynPropSitNumber;

typedef struct Z_pidEntityDynPropSitNumber Z_pidEntityDynPropSitNumber;
#endif /* __cplusplus */
#endif /* __Z_pidEntityDynPropSitNumber_FWD_DEFINED__ */

添加接口IZ_pidEntityDynPropSitNumber定义并绑定一个UID：

END_INTERFACE
} IZ_pidEntityDynPropSitNumberVtbl;
interface IZ_pidEntityDynPropSitNumber

#ifdef COBJMACROS

#endif /* COBJMACROS */

#endif /* __IZ_pidEntityDynPropSitNumber_INTERFACE_DEFINED__ */
Z_pidEntityDynPropSitNumber绑定另一个UID：

dual,
nonextensible,
helpstring("IZ_pidEntityDynPropSitNumber Interface"),

]
interface IZ_pidEntityDynPropSitNumber : IDispatch {

[

{
