Hi Scarta,
You can use the shared paramter name to get the parameter , then read the parameter value.
Here is the code snippet to show how to read the shared parameter value from the title block.
<TransactionAttribute(Autodesk.Revit.Attributes.TransactionMode.Manual)> _ Public Class RevitCommand2 Implements IExternalCommand Public Function Execute(commandData As ExternalCommandData, ByRef messages As String, elements As ElementSet) As Result Dim app As UIApplication = commandData.Application Dim doc As Document = app.ActiveUIDocument.Document Dim sel As Selection = app.ActiveUIDocument.Selection Dim ref1 As Reference = sel.PickObject(ObjectType.Element, "Please pick title block") Dim tb As FamilyInstance = TryCast(doc.GetElement(ref1), FamilyInstance) '''title block is a FamilyInstance If tb Is Nothing Then Return Result.Failed End If 'If the target shared parameter is from the family symbol/ family type. Dim param2 As Parameter = tb.get_Parameter("SharedParameterName") 'If the target shared parameter is from the family instance. 'Parameter param = tb.get_Parameter("SharedParameterName"); //directly use the shared parameter name 'show the fire rating in task dialog TaskDialog.Show("target shared parameter value", param2.AsString()) Return Result.Succeeded End Function End Class

Sorry, I used the code converter to convert the C# to VB.net. The code was not converted completely correct.
Here is the one should work.

Hi Scarta,
Please remove the get_ from below line.
'Parameter param = tb.get_Parameter("SharedParameterName"); //directly use the
VB.NET doesn't need the get_ for when calling the class get properties.

I have removed the _get but the problem is Parameter param, the error is: "Parameter is a type that can not be use as espression"

hI..with this procedure i can retrieve built in parameter but when I check value for shared parameter i retrieve "nothing"
I have used bitchecker with the title block, but I not retrieved any shared parameter...

Hi..
Ihave resolved the problem....I was finding the shared parameter on the Title block family, but sp was on the SHEET family!!
Thanks for your help!!
