• i am working on Script to get Parameter from Linked model.
• i used Python Script to get those Elements # i got output.
• i filtered Structural Framing "Categories" # i got output
• i filtered those elements through Nodes "Element.GetParameterValueByName" and "List FilterByBoolMark" with Parameter "Work Plane" # i got ouput.

#Issues

• For the output i am try to filter again through Node "Element.GetParameterValueByName" with Parameter "Type" # Warning: Element.GetParameterValueByName operation failed. Could not obtain element from the current document! The id may not be valid.

• For the output i am try to filter again through Node "Element.GetParameterValueByName" with Parameter "Family and Type" # Warning: Element.GetParameterValueByName operation failed. Could not obtain element from the current document! The id may not be valid.

#But i can see the values in Node "Element.Parameters" (List).

Selected Elements from linked file.zip

#May be, I think we may have other Node in different Packages to get that Value. So please suggest me.

if Possible answer why i cannot get output

Hi
I tryed to compile your project but i've got the following error message in DynamoBim console:

Any hints?

Hi Teocomi,

Sorry for a stupid question,
I added a new project, named Hello2, where I write a new SampleFunctions2 class and a new MultiplyTwoNumbers2 function.
I also added project Hello2 to HelloNodeModel project and build in Visual Studio. There is no error in building, but when I open Dynamo, the Dynamo node does not work. It contains an "internal error, please report: Dereferencing a non-pointer".

I have checked all files in project Hello2 and your Hello project. They are similar, so I don't where is the problem.
Please see the attached file for a screenshot and my project at https://drive.google.com/file/d/0B8Vuxlb1VZe3Sm50ZXJjRlNMb1E/view?usp=sharing

Thank you,

I built your source code, and imported to a Dynamo project, but result nodes are different from yours.
Please see the attached file.
