Macros that draw shapes in Excel 2007

[Jim]

I have some perfectly good code that draws shapes that works in Excel
2003 and Excel 2004 (Mac).
However, in Excel 2007 the results produced are very different. It
would seem that the shape definition parameters have changed. And of
course you can't learn by recording because parts of the recorder have
been disabled. Does anyone have a work around?
As an example, here's some code for drawing a circular arc that
smoothly joins one end of a trapezoid. Works fine in Excel 2003, but
not in 2007.
I'll be glad to provide the spreadsheet with the completed drawing.

Sub macro1()
rn = 0.1 * 3
theta = 75
rf = 0.096592583 * 3
rb = 0.364541775060029 * 3
lgth = 1 * 3
Call DrArc(100, 300, rn, theta, newlft, nm1)
lft = newlft
Call DrTrap(lft, 300, rf, lgth, rb, newlft, nm2)
End Sub
Sub DrArc(lft, mid1, r, thet, newlft, nm1)
'
r1 = 72 * r
rad = Atn(1) / 45
a1 = thet * rad
h1 = r1 * Sin(a1)
w1 = r1 * (1 - Cos(a1))

ActiveSheet.Shapes.AddShape(msoShapeArc, lft, mid1 - h1, r1, 2 *
h1).Select
Selection.ShapeRange.Adjustments.Item(1) = thet
Selection.ShapeRange.Adjustments.Item(2) = -thet
Selection.ShapeRange.Flip msoFlipHorizontal
Selection.ShapeRange.Height = 2 * h1
Selection.ShapeRange.Width = r1
nm1 = Selection.Name
Selection.Top = mid1 - h1
Selection.Left = lft
newlft = lft + w1
Call Grad_Fill(9)
End Sub

Sub Grad_Fill(kolor)
Selection.ShapeRange.Fill.Visible = msoTrue
Selection.ShapeRange.Fill.ForeColor.SchemeColor = kolor
Selection.ShapeRange.Fill.OneColorGradient msoGradientHorizontal,
4, 0.23
End Sub

Sub DrTrap(lft, mid1, rf, lng, rb, newlft, nm1)
l1 = 72 * lng
r1 = 72 * Application.WorksheetFunction.Min(rf, rb)
r2 = 72 * Application.WorksheetFunction.Max(rf, rb)
ActiveSheet.Shapes.AddShape(msoShapeTrapezoid, lft, mid1 - r2, 2 *
r2, l1). _
Select
Selection.ShapeRange.IncrementRotation 90#
If rf > rb Then Selection.ShapeRange.Flip msoFlipHorizontal
Selection.ShapeRange.Adjustments.Item(1) = (1 - r1 / r2) / 2
nm1 = Selection.Name
Call Grad_Fill(9)
Selection.Top = mid1 - r2
Selection.Left = lft
newlft = lft + l1
End Sub

SOLUTION
The problem has to do with the attributes ".Top" and ".Left" meaning
different things between Excel 2003 and 2007.
In both there are issues with what is left and top when shapes are
rotated.
And the definitions of arc and trapazoid are also different between
the 2 versions.

The work arounds are to use a whole circle instead of an arc and to
use a freeform to obtain a trapazoid and never, never rotate ever,
ever if you need to control location.
