[求助]样条曲线控制点数据的提取
Sub main()Dim selectObj As AcadSelectionSet
Set selectObj = ThisDrawing.ActiveSelectionSet
Save_Spline selectObj.Item(i)
End Sub
Private Sub Save_Spline(SplineObj As AcadSpline)
Dim fitPoints As Variant
Dim iCount As Long
fitPoints = SplineObj.fitPoints
Open "D:\10.txt" For Append As #1 'Open后面为数据的保存路径，每读取一条线要改一次名
For iCount = 0 To UBound(fitPoints) Step 3
X_scale = fitPoints(iCount)
Y_scale = fitPoints(iCount + 1)
X_scale = Format(X_scale, "##0.0000") '格式化数据，确定保留几位小数
Y_scale = Format(Y_scale, "##0.0000") '同上
Print #1, X_scale & " " & Y_scale '数据的输出格式
Next iCount
Close #1
End Sub
上面的代码就是提取控制点的小程序，可是每提取一条线的值我都得改一下名，效率太低！
哪位大侠能给我把这代码优化一下，我想每一次运行时能出现一个窗体来提示我改文件名。
谢谢了！
你提取的是样条曲线的拟合点而不是控制点。
需要使用VB的公用对话框控件来更改文件名。
