How to Add AEC Space?

ACA 2012


I am trying to figure out how to insert a 2D AEC Space with .net.  Using the code below, it appears as though a space is created but it shows up as only the "triangular error symbol".  I can select the symbol and it displays in the properties palette as a space,  Can anyone point me in the right direction as to the proper way to add an AEC Space?





 Using acTrans As Transaction = db.TransactionManager.StartTransaction()

            Dim acBlkTbl As BlockTable
            acBlkTbl = acTrans.GetObject(db.BlockTableId, OpenMode.ForRead)

            Dim acBlkTblRec As BlockTableRecord
            acBlkTblRec = acTrans.GetObject(acBlkTbl(BlockTableRecord.ModelSpace), OpenMode.ForWrite)

            Dim myPPO As New PromptPointOptions("Pick first point: ")
            myPPO.AllowNone = True
            myPPO.UseBasePoint = False

            Dim myPPR As PromptPointResult = ed.GetPoint(myPPO)
            Dim i As Integer = 0

            Dim acPoly As Polyline = New Polyline()

            While myPPR.Status = Autodesk.AutoCAD.EditorInput.PromptStatus.OK
                myPPO.UseBasePoint = True
                myPPO.BasePoint = myPPR.Value
                myPPO.Message = "Pick next point: "
                myPPR = ed.GetPoint(myPPO)
                i = i + 1
            End While

            If i > 3 Then

                acPoly.Closed = True

                acTrans.AddNewlyCreatedDBObject(acPoly, True)

                Dim myProfile As New Autodesk.Aec.Geometry.Profile
                Autodesk.Aec.Geometry.Profile.CreateFromEntity(acPoly, Matrix3d.Identity)

                Dim mySpace As Space = New Space
                mySpace.Associative = False
                mySpace.GeometryType = SpaceGeometryType.TwoD
                mySpace.Location = New Point3d(0, 0, 0)
                mySpace.SetBaseProfile(myProfile, Matrix3d.Identity)

                acTrans.AddNewlyCreatedDBObject(mySpace, True)

            End If

        End Using

Hi Chris,
I'm not sure, maybe it's a copy&paste error but I use the CreateFromEntity function so:
myProfile = Autodesk.AEC.Geometry.Profile.CreateFromEntity(mySpaceProfile, myEdsp.CurrentUserCoordinateSystem)

 myEDsp is the current Application.DocumentManager.MdiActiveDocument.Editor

hope this helps

Hi Holger,


Thanks for the quick response!  That was it.  You saved me lots of time.




btw, in my original post I left this code out by mistake.  It is inside my while loop.


acPoly.AddVertexAt(i, New Point2d(myPPR.Value.X, myPPR.Value.Y), 0, 0, 0)
