Summary: 커브 제어점의 3D 좌표값을 텍스트 파일로 내보내기

다음의 샘플 코드는 커브를 선택하고 해당 커브의 3D 좌표값을 텍스트 파일로 내보내는 방법을 소개합니다.

   Sub ExportControlPoints
 
     'Pick a curve object
     Dim strObject
     strObject = Rhino.GetObject("Select curve", 4)
     If IsNull(strObject) Then Exit Sub
 
     ' Get the curve's control points
     Dim arrPoints
     arrPoints = Rhino.CurvePoints(strObject)
     If Not IsArray(arrPoints) Then Exit Sub
 
     ' Prompt the user to specify a file name    
     Dim strFilter, strFileName
     strFilter = "Text File (*.txt)|*.txt|All Files (*.*)|*.*|"
     strFileName = Rhino.SaveFileName("Save Control Points As", strFilter)
     If IsNull(strFileName) Then Exit Sub
 
     ' Get the file system object
     Dim objFSO, objStream
     Set objFSO = CreateObject("Scripting.FileSystemObject")
 
     ' Open a text file to write to
     On Error Resume Next
     Set objStream = objFSO.CreateTextFile(strFileName, True)
     If Err Then
       MsgBox Err.Description
       Exit Sub
     End If
 
     ' Write each point as text to the file
     Dim strPoint, strText
     For Each strPoint In arrPoints
       strText = Rhino.Pt2Str(strPoint)
       objStream.WriteLine(strText)
     Next
 
     ' Close the file
     objStream.Close
 
   End Sub
