Title: How to edit a PolylineCurve2d constructor
Post by: Proctor on August 12, 2010, 01:27:03 PM

Hello: I'm working in Autocad 2009 .net api.

I have created a PolylineCurve2d and now can't figure out how to edit it. Here's my code I used to
create it:

Code: [Select]

Sub CreatePolylineCurve2d()
            Dim myPoints As New Geometry.Point2dCollection
            Dim myPLine As New PolylineCurve2d()
     
            For j As Integer = 0 To myEdge.lstLinesInEdge.Count - 1
                Dim oLine As Line = myEdge.lstLinesInEdge(j)
                Debug.Print(oLine.Length.ToString())
                oLine.Color = Autodesk.AutoCAD.Colors.Color.FromColor(Drawing.Color.MediumSeaGreen)
                myPoints.Add(New Geometry.Point2d(oLine.StartPoint.X, oLine.StartPoint.Y))
                myPoints.Add(New Geometry.Point2d(oLine.EndPoint.X, oLine.EndPoint.Y))
                myPLine = New PolylineCurve2d(myPoints)
            Next
            myPoints.Clear()
        End Sub

Now, I try to edit it - I try to do something like this:

Code: [Select]

myPLine.StartPoint = myOtherLine.EndPoint

And it tells me that myPLine's StartPoint is read only. What do I need to do to make my poly editable? I realize that this object is not a database object so I'm not sure if it's not editable?

Thanks for your help,
Proctor
