ObjectId.GetObject(OpenMode.ForWrite) error

JOH_DAE_RAE · January 2021

Hello everyone.
There is an error that occurs only in bricscad, so I ask a question

I am getting an error in the MoveCircle2 function below.
Is there a solution?

Imports Bricscad.ApplicationServices

Imports Teigha.Geometry

Public Class Class1
Dim acDoc As Document = Application.DocumentManager.MdiActiveDocument
Dim acCurDb As Database = acDoc.Database
Dim ed As Editor = Application.DocumentManager.MdiActiveDocument.Editor

<CommandMethod("MOVE-TEST")>
Public Sub MOVETEST()
    Dim acCirc As Circle
    acCirc = DrawCircle2(0, 0, 0.5)
    MoveCircle2(50, 50, acCirc)
End Sub

Private Function DrawCircle2(x As Double, y As Double, r As Double) As Circle
    Dim acCircD As Circle
    Using acTrans As Transaction = acCurDb.TransactionManager.StartTransaction()
        Dim acBlkTbl As BlockTable = acTrans.GetObject(acCurDb.BlockTableId, OpenMode.ForRead)
        Dim acBlkTblRec As BlockTableRecord = acTrans.GetObject(acBlkTbl(BlockTableRecord.ModelSpace), OpenMode.ForWrite)
        acCircD = New Circle
        acCircD.SetDatabaseDefaults()
        acCircD.Center = New Point3d(x, y, 0)
        acCircD.Radius = r
        acBlkTblRec.AppendEntity(acCircD)
        acTrans.AddNewlyCreatedDBObject(acCircD, True)
        Application.UpdateScreen()
        acTrans.Commit()
    End Using
    Return acCircD
End Function

Private Sub MoveCircle2(x As Double, y As Double, acCircM As Circle)
    Using acTrans As Transaction = acCurDb.TransactionManager.StartTransaction()
        Dim moveAcCirc As Circle
        moveAcCirc = acCircM.ObjectId.GetObject(OpenMode.ForWrite)   '' ////////////////  Error BricsCAD V20~
        moveAcCirc.Center = New Point3d(x, y, 0)
        moveAcCirc.Radius = 0.25
        Application.UpdateScreen()
        acTrans.Commit()
    End Using
End Sub

End Class

try
{
// MOVETEST
}
catch (System.Exception e)
{
Bricscad.ApplicationServices.Application.ShowAlertDialog(e);
}

It will give you some ideia of what is happening.
And it's a good ideia using try/catch when interacting with elements of the drawing.
