Zoom alignment

[joantopo]

Can I do this?

It is for entities of Autocad, but alignments are entitites of Autocad?

Public Shared Sub ZoomToEntity( _
                  ByVal entityId As ObjectId)
    Dim db As Database = Application. _
      DocumentManager.MdiActiveDocument.Database
    ' start transaction
    Using trans As Transaction = db. _
          TransactionManager.StartTransaction()
      ' get the entity' extends
      Dim ent As Entity = trans.GetObject( _
        entityId, OpenMode.ForRead)
      Dim extends As Extents3d = ent.GeometricExtents
      ' configure the new current view
      ZoomToWindow(New Point2d( _
                     extends.MinPoint.X, _
                     extends.MinPoint.Y), _
                   New Point2d( _
                     extends.MaxPoint.X, _
                     extends.MaxPoint.Y))
      trans.Commit()
    End Using
  End Sub
 
  ' the command for database extension
  <CommandMethod("zextends")> _
  Public Shared Sub ZoomExtends()
    Dim db As Database = Application. _
      DocumentManager.MdiActiveDocument.Database
    'get the database extension's points
    ZoomToWindow(New Point2d( _
                  db.Extmin.X, db.Extmin.Y), _
                 New Point2d( _
                  db.Extmax.X, db.Extmax.Y))
  End Sub

Other way could be this:

 public static void ZoomObjectoSeleccionado(Autodesk.AutoCAD.DatabaseServices.ObjectId[] matriz)
        {
           Autodesk.AutoCAD.Internal.Utils.SelectObjects(matriz);
         Autodesk.AutoCAD.Internal.Utils.ZoomObjects(false);
          System.Windows.Forms.Application.UseWaitCursor = false;

        }

 But with zoom I don´t want to select alignment.

Yes, the code snippet in the AutoCAD DevBlog should work fine for Civil 3D entity as well.
