Program closes before if statement (CATIA VBA) - vba

Question

I am trying to implement a minimum boundary box subroutine inside my macro. Subroutine ends before going into if statement. Can you help me find the solution?
Option Explicit
Sub bounding()
Dim partDocument1 As PartDocument
Set partDocument1 = CATIA.ActiveDocument
Dim part1 As Part
Set part1 = partDocument1.Part
Dim hybridShapeFactory1 As HybridShapeFactory
Set hybridShapeFactory1 = part1.HybridShapeFactory
Dim hybridBodies1 As HybridBodies
Set hybridBodies1 = part1.HybridBodies
Dim hybridBody1 As hybridbody
Set hybridBody1 = hybridBodies1.Item(cevap)
Dim hybridShapes1 As HybridShapes
Set hybridShapes1 = hybridBody1.HybridShapes
Dim axisSystems1 As AxisSystems
Set axisSystems1 = part1.AxisSystems
Dim axisSystem1 As AxisSystem
Set axisSystem1 = part1.FindObjectByName("axissys")
Dim direction As Long
If extindex Mod 2 = 1 Then
direction = 1
Else
direction = 0
End If
Dim reference1 As Reference
MsgBox CStr(extindex)
Select Case extindex
Case 1, 2
Set reference1 = axisSystem1.XAxisDirection
MsgBox CStr(extindex) + "1ve2"
Case 3, 4
Set reference1 = axisSystem1.YAxisDirection
MsgBox CStr(extindex) + "3ve4"
Case Else
Set reference1 = axisSystem1.YAxisDirection
MsgBox CStr(extindex) + "5ve6"
End Select
Debug.Print ("exit if check")
Dim hybridShapeDirection1 As HybridShapeDirection
Set hybridShapeDirection1 = hybridShapeFactory1.AddNewDirection(reference1)
Dim bodies1 As Bodies
Set bodies1 = part1.Bodies
Dim body1 As Body
Set body1 = bodies1.Item("PartBody")
Dim reference2 As Reference
Set reference2 = part1.CreateReferenceFromObject(body1)
Dim hybridShapeExtremum1 As HybridShapeExtremum
Set hybridShapeExtremum1 = hybridShapeFactory1.AddNewExtremum(reference2,
hybridShapeDirection1, 0)
part1.Update
hybridBody1.AppendHybridShape hybridShapeExtremum1
part1.InWorkObject = hybridShapeExtremum1
hybridShapeExtremum1.Name = "ext1" + CStr(extindex)
part1.Update
End Sub
All variables on the program are checked and they work. I don't understand what is happening an why it doesnt work. I even checked all variables. Program should go inside if statement but it doesnt

The AxisSystem properties XAxisDirection, YAxisDirection, and ZAxisDirection refer to the references from which the axis system was defined.
You can use these properties to edit the AxisSystem object itself but they are not "output" Reference objects which should be used to construct downstream geometry.
You can pull the vectors components using the GetXAxis, GetYAxis, and GetZAxis methods (which will always contain values) and then use HybridShapeFactory.AddDirectionFromCoord() method to create the direction for the extremum.

MsgBox CStr(extindex)
Dim vect(2)
Dim vAxis As Variant
Set vAxis = axisSystem1
Select Case extindex
Case 1, 2
vAxis.GetXAxis vect
Case 3, 4
vAxis.GetYAxis vect
Case Else
vAxis.GetYAxis vect
End Select
Dim hybridShapeDirection1 As HybridShapeDirection
Set hybridShapeDirection1 = hybridShapeFactory1.AddNewDirectionByCoord(vect(0), vect(1), vect(2))
