is it possible to "extract" a parameter into a "tag" (or similar)

[luigi]

Basically, if there is a parameter containing data, i.e. Top of wall or footing, can this data, through the API, be extracted and placed in a tag (or something similar)?
Thanks in Advance!

Yes it is possible but it takes a lot of code. You have to pull the object and scan thru its parameters until you find the one that you want and then you can set it to a variable. I did one similiar to this with a macro I wrote for room number tags. The code is about a page and half long.

Well, here's a VB.Net version !

Assuming you already have a loop that gets the element for you, you can use the following 2 functions to get the parameter in a string format .... and then store it in a tag may be ! You may have to modify the things slightly ...

******* YOU WILL HAVE TO REPLACE "ParemeterName" IN THE CODE WITH YOUR ACTUAL PARAMETER NAME **********************************

'Function to get the value of a specific parameter
Public Function GetParamVal(ByVal elem As Autodesk.Revit.Element) As String

            Dim paramIter As Autodesk.Revit.ParameterSetIterator
            paramIter = elem.Parameters.ForwardIterator
            While (paramIter.MoveNext)
                If (CType(paramIter.Current, Autodesk.Revit.Parameter).Definition.Name _ 
                       = "ParameterName") Then
                    
                   return ParameterValue(paramIter.Current)
               End If

            End While
            Return ""
End Function

'Function to convert the value of an element.parameter to a string 
Private Function ParameterValue(ByVal param As Autodesk.Revit.Parameter) As String
            If (param Is Nothing) Then
                Return ""
            End If

            Dim value As String = ""
            Select Case param.StorageType
                Case Parameters.StorageType.Double
                    value += param.AsDouble().ToString()
                Case Parameters.StorageType.ElementId
                    value += param.AsElementId().ToString()
                Case Parameters.StorageType.Integer
                    value += param.AsInteger().ToString
                Case Parameters.StorageType.None
                    value += "NONE"
                Case Parameters.StorageType.String
                    value += param.AsString()
                Case Else
                    value += "ELSE CASE"

            End Select
            Return value
End Function
