VBA Macro TO Export Splines from catia to text file(.dat) - vba

Question

so I was wondering if i could get some help here. so basically i am trying to find out how to write a dat file that will be able to import splines into Catia. These splines when imported are supposed to act like meshes on a structure, that is, picture a meshed structure, but instead of mesh it will be splines on it. so right now i thought to learn a macro that exports a few splines i created on a structure into a text(.dat) file. but i have been having troubles with the macro i have as it asks me to select a spline, but wont allow me to click on the spline in spec tree. The thing is that i have lots of splines and i would like the macro to just select splines automatically without asking and export them..... PLS HELP ME. thanks alot.
So here is the code:
Sub CATMain()
'*** *** Definition Variables
Dim CtrlPoint()
Dim oCoordinates(1)
Dim StartKrit As Integer
'*** Query document type ***
StartKrit = 0
Set oDoc = CATIA.ActiveDocument
ObjType = TypeName(oDoc)
If ObjType = "PartDocument" Then
DocType = "Part"
StartKrit = 1
ElseIf ObjType = "DrawingDocument" Then
DocType = "Drawing "
StartKrit = 1
End If
If StartKrit = 0 Then
box = MsgBox(" The active document is neither a CATPart still CATDrawing! " + Chr(10) + _
" The macro can not continue and will now exit " + Chr(10) + _
"Please select a CATPart or a CATDrawing and start the macro again!", vbCritical + vbOKOnly, "incorrect document type")
Exit Sub
End If

If box = vbNo Then
box = MsgBox(" The macro is now finished ", vbInformation + vbOKOnly, " the user stops ")
Exit Sub
End If
End If
Set A = fs.CreateTextFile("D:\school\INTERNSHIP\Macro\Newest.txt ", True)
A.WriteLine (" points coordinates of a spline ")

Your selectelement2 filter is set for spline2D, are you selected sketch splines or 3d splines?
If you are working with 3d splines like it sounds, you want to use this code:
mysel.Clear
otype3D(0) = "HybridShapeSpline"
mysel.Clear
box = MsgBox("Please select now the spline", vbInformation + vbOKCancel, "spline Select")
If box = vbCancel Then
box = MsgBox("you have canceled the selection" + Chr(10) + _
"The macro is now finished!", vbCritical, "abort by user")
If fs.FileExists(StorePath & StoreName & ".txt") = True Then
A.Close
fs.DeleteFile (StorePath & StoreName & ".txt ")
End If
Exit Sub
End If
Selection = mysel.SelectElement2(otype3D, " Please select the spline ", False)
