希望有大神能够帮我修改下VBA程序
新手小白，为完成课程设计。边看书，边做。为实现自动生成一对斜齿轮，只要出图就行。思路是先画一个轮齿的齿廓，然后阵列，然后拉伸成为一个实体。
错误可能有点多，望谅解~真心求助。

你把vba文件发上来，不然窗体中哪么控件，添加也很麻烦！
这么多代码，不调试很难知道哪错了
附件已上，今天又修改了一下。感觉还是很多不对的地方，求指教，谢谢了
楼主，几点建议
1、开明白vb语法中的数据类型，z1 = Me.TextBox7，z1得到的是字符串，不能进行数学运算，
改为z1 = Val(Me.TextBox7)，这样的代码很多！
2、ε = (((df2) ^ 2 - (db2) ^ 2) ^ -2) / db2,这么多括号是干吗的？你要搞明白vb的运算优先级！这完全可能改为：ε = Sqr(df1 ^ 2 - db1 ^ 2) / db1
3、ε = Sqr(df1 ^ 2 - db1 ^ 2) / db1，既然要开平方，必须保证df1 ^ 2 - db1 ^ 2是正数！你给你例子得出结果是负数！
4、Dim p1(0 To 1) As Double
Dim P2(0 To 1) As Double
....
Call ThisDrawing.ModelSpace.AddLine(p1, P2)
vba帮助内容
RetVal = object.AddLine(StartPoint, EndPoint)
ModelSpace 集合, PaperSpace 集合, Block
使用该方法的对象。
StartPoint
Variant[变体] (三元素双精度数组); 仅用于输入
指定直线起点的三维WCS坐标。
EndPoint
Variant[变体] (三元素双精度数组); 仅用于输入
指定直线终点的三维WCS坐标。
StartPoint，EndPoint都是三维点，你定义成了二维点。。
5、Public AcadApp As AcadApplication '定义了AcadApp 对象，但是从来没有对它进行实例化，也就是AcadApp 没有指向一个真正的对象，而后面直接用：
AcadApp.ActiveDocument.CloseAcadApp.Documents.Add
当然出错了！
这里可以用：Set AcadApp = ThisDrawing.Application 实例化
后面的没细看，你还是改改吧，尤其是vb的基础，一定要弄明白，还有一些编码的规则也学学，如变量的明确定义，变量的命令规则等

感谢大神悉心指导，做课程设计太赶了，没那么多时间看书，慢慢的才了解一点点了。
