acdbtext如何加入AcDbDatabase
本帖最后由 BDYCAD 于 2013-6-24 15:27 编辑//InObjIDList为输出对象ID表
//fileName为输出文件名称，格式如_T("C:\\abc.dwg")

}如上代我近来正在写的代码。是把对象输出一个DWG文件，但是文字输不出，请高手指点一下我，怎么写才对？？

有答案吗，我也想知道 看来没人肯回答阿。
那我来把
1，运行时识别，直接用下面的
if (pEnt->isKindof( AcDbText::desc ) )//判断实体是不是acdbtext，其他对象同此操作
{....}
2，你这个是将选中的代码另存为一个dwg，直接使用pNewEnt = pEnt->clone()，来在内存中创建一个与pEnt一模一样的对象。其余不用变。 感 谢楼上大侠：）
