I have a projection drawing from 3d, i need to find holes in circle in 2d drawing bane with macro but failed. Can anyone help me see where the error is?
Sub CATMain()

Dim drawingDocument1 As DrawingDocument
Set drawingDocument1 = CATIA.ActiveDocument

Dim SelectionsAll As Selection
Set Selection = drawingDocument1.Selection
MsgBox Selection.Count2
For i = 1 To Selection.Count2
Set RefView1 = Selection.Item(i).Value
Set Element = RefView1.GeometricElements
'Set Element = refView.GeometricElements.GetCurvature RefView
MsgBox TypeName(Element)
Select Case TypeName(Element)
Case "Axis2D":
MsgBox "Axis"
Case "Line2D":
MsgBox "line"
Case "Circle2D":
MsgBox "Circle"
End Select
Next
MsgBox "finish"
End Sub

Do you mean to count circles appearing in 2D sheet? If you want to find anything its not right code, firstly i recommend using method selectelement3 with triggering palette instead of preselection.

Little Cthulhu do you have any command to find them? tôi đang muốn tạo một macro như lệnh " hole dimension table" của catia

You can find the circle by Isolating the link.
This is not a very pretty method, but here is an example of temporarily copying and pasting a view, Isolating it, and then deleting it once the necessary information is retrieved.
A new view is created near the origin, and the result is text for each diameter.
Code:
'vba

Thanks. I see this code select all arcs (not closed circles) how can only closed circles be selected?

Rewrite the get_circles function next and add the is_close_circle function.
