我已经尝试了你的两个建议，但它并没有改变砌块的层数..
为了让我头脑清楚，我应该把函数放在哪里？我认为它在主命令按钮的sub或插入块的过程之前，所以它首先计算函数。我有这种方法，但是我不能让它工作..
如果我在下面贴出我的整个代码(我不能贴出用户表单，但我相信你们可以想象它lol) -哦，原谅任何编码的粗糙，我几乎是自学的，所以如果你有时间，任何关于干净代码的指示都将非常感谢:

私有函数DoesLayerExist（）作为字符串＜br＞此函数必须返回字符串layername Hi Bryco，
我试过了(除了您展示的代码行之外，没有更改其他代码)，但它返回来说没有设置objLayer变量，尽管它在函数中设置了。有什么想法吗？ 这是从一些模糊的记忆中产生的，所以我会让你决定它是否有价值，但它可能值得一试。如果我没记错的话，如果图层已经存在，用VBA制作图层不会有任何影响，所以你可以尝试取消检查功能，每次都制作图层。除此之外，您可以在主sub中进行检查，而不是将其分解到一个函数中。
