Create an ellipse (oval), rotate it 15deg, convert it to curves.
I created this macro to replace the shape with an ellipse but would like to add to it. I'd like to get the angle of rotation of the shape then after the shape is replaced have it rotate it to what it was.
Could probably be streamlined too but beyond my code hacking skills.
Sub ConvertCirclesBack() Dim sr As ShapeRange, s As Shape Dim x#, y#, w#, h#, dOffset# ActiveDocument.BeginCommandGroup ("Convert") Set sr = ActiveSelectionRange If sr.Shapes.Count < 1 Then MsgBox "Select at least one shape" Exit Sub End If Optimization = True ActiveDocument.Unit = cdrInch If sr.Count = 0 Then Exit Sub For Each s In sr s.GetBoundingBox x, y, w, h Set s = ActiveLayer.CreateEllipse2(x + w / 2, y + h / 2, w / 2, h / 2) s.Flip cdrFlipVertical Next s sr.Delete Optimization = False ActiveWindow.RefreshActiveDocument.EndCommandGroupEnd Sub

If a Curve was created in the way you describe, then it will have four nodes.
Some math could be used to use the coordinates of those nodes - or the coordinates of two of those nodes, and also of the center - to figure out the Radius1 and Radius2 values for the new Ellipse, and the angle to which you would need to rotate it.
That's just off the top of my head. I haven't given much thought to whether there is any really clever way to do it. I guess one way to do less math would be to create a couple of two-node Curves based on the center and two of the nodes, and then get the lengths and angle from them. You wouldn't have to create actual Curve shapes in the document to do that.
if you only had a few of these to do, it's pretty quick to draw a new Ellipse manually using the 3-Point Ellipse tool, and snapping to the nodes of the existing curve shape.
The need for the macro came from autocad files where the ovals were made up of line segments instead of smooth ellipses. Sometimes there can be hundreds of them.
I do agree that an algorithm would need to be used as the shapes wouldn't carry any rotation info with them anyway. I was basing the idea off my own rotation of a shape where the shape already carries the info with it.
Your macro draws an ellipse very similar but not identical to the originalHere is my version of this macro belowThere is also a condition that the nodes of the curve must be standard as when converting an ellipse into a curve.TarasSub TV_CirclesBack() Dim SR As ShapeRange, s As Shape, s1 As Shape, kut As Double Dim X1 As Double, Y1 As Double, X2 As Double, Y2 As Double Dim XC As Double, YC As Double, R1 As Double, R2 As Double ActiveDocument.Unit = cdrMillimeter Set SR = ActiveSelectionRange For Each s In SR XC = s.CenterX YC = s.CenterY X1 = s.Curve.Nodes(1).PositionX Y1 = s.Curve.Nodes(1).PositionY R1 = Distance(X1, Y1, XC, YC) X2 = s.Curve.Nodes(2).PositionX Y2 = s.Curve.Nodes(2).PositionY R2 = Distance(X2, Y2, XC, YC) Set s1 = ActiveLayer.CreateLineSegment(X1, Y1, XC, YC) kut = s1.Curve.Segments(1).StartingControlPointAngle s1.Delete Set s1 = ActiveLayer.CreateEllipse2(0, 0, R1, R2) s1.Rotate kut s1.CenterX = XC s1.CenterY = YC Next s SR.Delete End SubFunction Distance(X1 As Double, Y1 As Double, X2 As Double, Y2 As Double) Distance = Sqr(Abs(X2 - X1) ^ 2 + Abs(Y2 - Y1) ^ 2)End Function
