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: Const pi = 3.14159 Private sp(0 To 2) As Double Private ep(0 To 2) As Double Private hwidth As Double Private trad As Double Private tspac As Double Private pangle As Double Private plength As Double Private totalwidth As Double Private angp90 As Double Private angm90 As Double ' 将角度从度转换为弧度 Function dtr(a As Double) As Double dtr = (a / 180) * pi End Function ' 计算两点之间距离 Function distance(sp As Variant, ep As Variant) _ As Double 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)) End Function ' 获取花园小路的信息 Private Sub gpuser() Dim varRet As Variant varRet = ThisDrawing.Utility.GetPoint( _ , "Start point of path: ") sp(0) = varRet(0) sp(1) = varRet(1) sp(2) = varRet(2) varRet = ThisDrawing.Utility.GetPoint( _ , "Endpoint of path: ") ep(0) = varRet(0) ep(1) = varRet(1) ep(2) = varRet(2) hwidth = ThisDrawing.Utility. _ GetDistance(sp, "Half width of path: ") trad = ThisDrawing.Utility. _ GetDistance(sp, "Radius of tiles: ") tspac = ThisDrawing.Utility. _ GetDistance(sp, "Spacing between tiles: ") pangle = ThisDrawing.Utility.AngleFromXAxis( _ sp, ep) totalwidth = 2 * hwidth plength = distance(sp, ep) angp90 = pangle + dtr(90) angm90 = pangle - dtr(90) End Sub
