My task is to write an automated routine that checks for a certain classification added to Duct objects.

In the classification definition SfB all classification names of the form (XX)X should be altered/renamed to the form XX.X

Defining a Classification object Classfc as Autodesk.Aec.DatabaseServices.Classification my problem is that the property Classfc.Name is readonly

I struggled with finding another way to solve the problem but have not been able to find a solution.

Any ideas?

Hi Jan,

How about Rename() method of DictionaryClassificationDefinition class?  Dictionary is a container class of dictionary record.  If you haven't looked at it, could you try?

Thanks t for the hint. I will give it a try and let you know how it went.

Hi Mikako

That got me some of the way. Now I can rename the classification definition using the code below. Now I just need to rename som nodes inside the classification tree. However I am having troubles using the classificationtree-rename method. (Have a look at the RenameClassification below).

Any sugestions?

Code example:

<Autodesk.AutoCAD.Runtime.

CommandMethod("RenameClassificationDef")> _

PublicSub RenameClassificationDef()

Dim ed AsEditor = Application.DocumentManager.MdiActiveDocument.Editor

Dim db AsDatabase = HostApplicationServices.WorkingDatabase

Dim dictClsfcDef AsDictionaryClassificationDefinition = NewDictionaryClassificationDefinition(db)

Dim id AsObjectId = dictClsfcDef.GetAt("AAU_SfBClassification")

Try

Using tr AsTransaction = db.TransactionManager.StartTransaction

Dim SfBClsfc AsObjectId

Dim AAUClsfc AsObjectId

Try

                    SfBClsfc = dictClsfcDef.GetAt(

"SfB")

Catch

EndTry

Try

                    AAUClsfc = dictClsfcDef.GetAt(

"AAU_SfBClassification")

Catch

EndTry

If AAUClsfc.IsNull AndAlsoNot SfBClsfc.IsNull Then

                    dictClsfcDef.Rename(

"SfB", "AAU_SfBClassification", tr)

EndIf

Dim Recs AsObjectIdCollection = dictClsfcDef.Records

ForEach RecID AsObjectIdIn Recs

Dim RecObj AsClassificationDefinition = RecID.GetObject(OpenMode.ForWrite)

Dim VVSID AsObjectId = RecObj.GetClassification("VVS-anlæg")

Dim VVSObj AsClassification = VVSID.GetObject(OpenMode.ForWrite)

Next

                tr.Commit()

EndUsing

Catch ex AsException

            ed.WriteMessage(

"Error : " + ex.ToString + vbCrLf)

EndTry

EndSub

Here is the RenameClassification-sub (that fails):

Public Sub RenameClassification(ByRef tr AsTransaction, ByRef node AsClassificationTree)

Dim ed AsEditor = Application.DocumentManager.MdiActiveDocument.Editor

If node IsNothingThen

Return

EndIf

IfNot (node.Id.IsNull) Then

Dim classi AsClassification = CType(tr.GetObject(node.Id, OpenMode.ForRead), Classification)

            node.Rename(classi.ObjectId,"SomeNewName") THIS FAILS!

EndIf

If node.Children.Count > 0 Then

ForEach ChildTree In node.Children

                RenameClassification(tr, ChildTree)

Next

EndIf

EndSub

Hi Jan,

Could you post this question to AutoCAD Architecture customization forum? 

http://forums.autodesk.com/t5/AutoCAD-Architecture/bd-p/54

Sounds like your question became AutoCAD Architecture specific. The audience of this forum is probably wondering what we are talking about :-)  It will be more appropriate to post in AutoCAD Architecture one.  

Glad to hear you have solved the initial question of renaming the classification definition.

Thank you for cooperation.

I will do that.
Thanks so far :-)
