如何将选中的实体保存到另一个文件？
要求原有的实体属性不变。

1、创建一个对象数组，保存选中实体。如：Dim objCollection(0 To 1) As Object
2、打开那个文件，如：doc。
3、使用ThisDrawing.CopyObjects objCollection,doc，将实体拷贝到刚打开的文件中。

CopyObjects 的参数如何设置，我老是设不对
doc1 对象所在文件
doc2 目标文件
objCollection 对象集
doc1.CopyObjects (objCollection， doc2)
但我这样设后，还是出错，“CopyObjects 不能应用在IAcadDocument 上"

用Wblock

最初由 gephen 发布
[B]CopyObjects 的参数如何设置，我老是设不对
doc1 对象所在文件
doc2 目标文件
objCollection 对象集
doc1.CopyObjects (objCollection， doc2)
但我这样设后，还是出错，“CopyObjects 不能应用在IAcadDocumen... [/B]

我想是应该要进入modelspace,或者其他的对象中吧!
doc1.modelspace.CopyObjects (objCollection， doc2.modelspace)

"对象所在文件"还不是对象集的"上级"

如果要求实体拷贝到另一文件中后变化比例，要求图形变大或变小时，用VBA如何实现？
