C++和ObjectARX開發一例
//-----------------------------------------
//開發環境
//vs2008+ObjectArx2010+AutoCAD2010
//vs2008新建一個win32項目或者MFC DLL項目
//vs2008設置項目屬性->配置屬性->C/C++->常規->附加包含目錄=E:\AutoCad開發\ObjectARX2010\inc
//vs2008設置項目屬性->配置屬性->連接器->常規->輸出文件=$(OutDir)\$(ProjectName).arx
//vs2008設置項目屬性->配置屬性->連接器->常規->附加庫目錄="E:\AutoCad開發\ObjectARX2010\lib-win32"
//vs2008設置項目屬性->配置屬性->連接器->輸入->附加依賴項=rxapi.lib acdb18.lib acge18.lib acad.lib acedapi.lib

//ObjectARX offers the following input functions. Refer to the ObjectARX Online Help for a complete description of how to use these functions.
//acedGetInt used to get an integer value
//acedGetReal used to get a real value
//acedGetString used to get a string
//acedGetAngle used to get a angle value
//acedGetKword used to get a key word
//acedInitGet used to initialize acedGetXXXX functions
//acedGetFileD used to retrieve file selection from a file dialog
//acedGetPoint used to pick a point
//acedGetDist used to get the distance between two points
//acedGetCorner see Online Help for a complete description
//
//ObjectARX offers the following functions for selection of AutoCAD entities. (Again refer to the ObjectARX Online Help for a complete description of how to use these functions).
//
//acedEntSel used to select a single entity
//acedNEntSel used to select a single, nested entity
//acedNEntSelP used to select a single, nested entity
//acutSSGet used to select multiple entities
//---the end----
