[VBA程序]：请教版主

请教版主vba中能不能用函数来实现将所选择的实体做成块!

当然可以，简单点的使用CopyObjects直接将实体拷贝到块中，更省去了写块的操作。

不好意思,版主,偶比较菜,还是不明白,怎么将我所选择的实体用copyobject到块中.

efan2000

首先在块集合中创建一个块，返回块对象，如BlockObj。然后将选择集中的所有实体存入一个对象数组，如objCol。接着使用CopyObjects objCol, BlockObj。CopyObjects的第一个参数是对象数组第二个参数是存放拷贝后的对象的容器，可以用来作为空器的有块、模型空间等，也可以是另一个文档的模型空间。
