怎么在autocad 命令栏中 调用dvb程序？
我按照cad帮助里编辑了一下gardenpath的程序，在vb编辑器中点击运行，可以在cad绘图窗口使用。但是我想把它作为一个程序，就像调用line一样，在命令栏中输入‘line’即可花直线。高手指点一下。我加载过，但是加载完老说，没有此（gardenpath）命令源码：

Private totalwidth As Double
Private angp90 As Double
Private angm90 As Double
' 将角度从度转换为弧度

dtr = (a / 180) * pi
End Function
' 计算两点之间距离

Dim x As Double
Dim y As Double
Dim z As Double
x = sp(0) - ep(0)
y = sp(1) - ep(1)
z = sp(2) - ep(2)
distance = Sqr((Sqr((x ^ 2) + (y ^ 2)) ^ 2) + (z ^ 2))
