How do I add nodes at equal distance to segments with different lengths?

draw circle, radius = specified distance, set circle's centre on first node, intersection with segment will be point of next node

While doing some search on my own I found this code and modified it to just draw tangents:
getperpendicularat

Sub GetPerpendicularAt_Test()
'uses MarkPointOnPerpendicular
Dim seg As Segment
Dim t As Double
Dim count As Integer
count = 40
If ActiveShape Is Nothing Then
MsgBox "nothing selected"
Exit Sub
End If


For Each seg In ActiveShape.Curve.Segments
For t = 0 To count Step 2
MarkPointOnPerpendicular seg, t / count, 0.2
Next t
Next seg
End Sub

Private Sub MarkPointOnPerpendicular(seg As Segment, t As Double, curveLength As Double)
'used by GetPerpendicularAt_Test method
Dim x As Double, y As Double
Dim dx As Double, dy As Double
Dim a1 As Double, a2 As Double
seg.GetPointPositionAt x, y, t, cdrRelativeSegmentOffset
a1 = seg.GetTangentAt(t, cdrRelativeSegmentOffset) ' * 3.1415926 / 180
a2 = seg.GetPerpendicularAt(t, cdrRelativeSegmentOffset) * 3.1415926 / 180
'dx = 0.5 * Cos(a1)
'dy = 0.5 * Sin(a1)
'With ActiveLayer.CreateLineSegment(x, y, x + dx, y + dy)
' .Outline.EndArrow = ArrowHeads(1)
'End With
dx = curveLength * Cos(a2)
dy = curveLength * Sin(a2)
ActiveLayer.CreateLineSegment x, y, x + dx, y + dy
End Sub

As far as I can figure it out, the "seg.GetPointPositionAt x, y, t, cdrRelativeSegmentOffset" is the key here. This gets the points coordinates at equal distance along the segment and "ActiveLayer.CreateLineSegment x, y, x + dx, y + dy" uses thos x and y values to create a line from those points.

Need help to alter this code to add nodes at those x and y coordinates, instead of creating lines.

Thanks.
