View filters cannot be directly modified using the Tekla Open API. The only possible option regarding view filters and the API, is to change the current view filter to another view filter from the list of available views filters.

Step 1, Add Libraries:

Add reference to the Tekla.Structures.Model library located in the path “C:Program FilesTekla Structures20.0ntbinplugins” and manually open the tekla model. This has been covered in the article below:

• VB.Net Open Tekla Structure Model (Tekla Open API)

Change View  Types:

Using the code below the view filters of all the available views are changed to a view filter with the name “MyNewFilter”

Imports TSM = Tekla.Structures.Model

    Private Sub ChangeViews()
        Dim objViewEnum As TSM.UI.ModelViewEnumerator
        Dim objView As TSM.UI.View

        objViewEnum = TSM.UI.ViewHandler.GetAllViews
        While objViewEnum.MoveNext
            objView = objViewEnum.Current

            objView.ViewFilter = "MyNewFilter"
            objView.Modify()
        End While

    End Sub
