excel to catia

Hi All,
I recorded this macro from a CAD program, called CATIA. What it does is creates a point and a sphere. what i want it to do is to loop for as many rows in an an excel spreadsheet. the spreadsheet is where i get my x,y & z values for the point.
Does anyone know how to solve this problem. Thanks.
Language="VBSCRIPT"

Sub CATMain()

Set documents1 = CATIA.Documents

Set partDocument1 = documents1.Add("Part")

Set part1 = partDocument1.Part

Set hybridBodies1 = part1.HybridBodies

Set hybridBody1 = hybridBodies1.Add()

Set hybridShapeFactory1 = part1.HybridShapeFactory

Set hybridShapePointCoord1 = hybridShapeFactory1.AddNewPointCoord(0.000000, 0.000000, 0.000000)

hybridBody1.AppendHybridShape hybridShapePointCoord1

part1.InWorkObject = hybridShapePointCoord1

part1.Update

Set reference1 = part1.CreateReferenceFromObject(hybridShapePointCoord1)

Set hybridShapeSphere1 = hybridShapeFactory1.AddNewSphere(reference1, Nothing, 76.200000, -45.000000, 45.000000, 0.000000, 180.000000)

hybridShapeSphere1.Limitation = 1

hybridBody1.AppendHybridShape hybridShapeSphere1

part1.InWorkObject = hybridShapeSphere1

part1.Update

End Sub

VB Code:

Dim intRowCounter 'As Integer
    
For intRowCounter = 1 To UsedRange.Rows.Count
    
Next intRowCounter

I've taken off the variable data type there as you put you're using vbscript. In Excel, there is a UsedRange object which you can reference above to find the amount of used rows in a worksheet and start a loop from.
