Hello, I’m trying to get the value of a family type parameter with Dynamo using the Element.GetParameterValueByName block. However, when I plug in the correct element and parameter name, the block outputs nothing. When I output the Element.Parameters to verify, it looks like they are null as well …

Orchid has some nodes for dealing with family documents, including one for parameter values. With those and a little python node to get the names of the parameter elements, you should be able to get exactly what you want. [image]

@daniel.astorino , did you check whether you are still in a workmode or accidantly a window is still open so your script can`t execude?

To piggyback on what @Draxl_Andreas suggested, if you’ve been working on the same script for a while, maybe try saving and restarting the Dynamo Editor.

yes it definitely looks like it’s running since I’m getting output at almost every block. As shown in my screenshot, it’s really only the Element.GetParameterValueByName that appears as blank even though I’m not getting any errors or warnings. Also the Element.Parameters doesn’t look right either.

@daniel.astorino wait a minute [grafik] you have a parameter as input not a Element whats in the python code ?

oh I see. My “Get Element ID from FamilyDoc Parameters” essentially gets a FamilyParameter Element (Autodesk.Revit.DB.FamilyParameter) then outputs the .Id of the FamilyParameter as shown below. I then GetElement with that ID. [image] @Draxl_Andreas I guess my question now becomes: is there a way…

[image] I essentially want to extract the value associated with the family type parameter. So for the Depth example, I would want to get back 1750.00 This being the case I thought Element.GetParameterValueByName would be the best block to use, but to do so I need the Element, not the Parameter el…

@Draxl_Andreas I took a look, but I’m not sure if this is exactly what I need to get Value from a family type parameter. I tried using the line of code FilteredElementCollector(doc).OfClass(FamilyElement).WherePasses(filter).FirstElement() but it still returns IDs that again give me ParameterElement…

You’re sort of mixing processes. Where are you getting the family document from? Why do you need to get the value from the document and not an instance of the family or type? If we had more information on your process we might be able to suggest a better solution. Your Id is for a parameter which y…
