實現函數

	static void AAAMyGroupMyCommand () {
		// Put your command code here
		acutPrintf(_T("MyCommand () "));

		//創建直線
		acutPrintf(_T("創建直線"));
		AcDbObjectId lineId;
		lineId = CreateLine();

		//修改直線的顏色
		acutPrintf(_T("修改直線的顏色"));
		ChangeColor(lineId, 1);

	}

編譯，出現錯誤：

可是已經在acrxEntryPoint.cpp中包含了頭文件#include "Modify.h"。

解決方法：

<類名>::<靜態成員函數>

lineId = Modify::CreateLine();

Modify::ChangeColor(lineId, 1);

因爲

static AcDbObjectId CreateLine();

static ErrorStatus ChangeColor（）；

兩個函數爲靜態成員函數，調用是需要加 <類名>::
