Hi there,  
pretty new here on dynamosphere… I’m starting out and trying to create a small script to do the following :

- read a specific parameter value from a structural floor element
- find out the analytical counterpart of that floor
- create a hosted load on that analytical floor depending on the parameter value read before.

I found an example on creating a hosted load but don’t know how to find the analytical version of the selected structural floor element. Any helps is greatly appreciated, thank you…

Hello!

- To get parameters use the Element.GetParameterValueByName node
- To get the anlytical model of any element create a python node and use the [GetAnalyticalModel method](http://www.revitapidocs.com/2017/351c2ce0-70c6-62e1-e675-5bd4c259d756.htm)

To get more specific help you have to try first, and then post a screenshot and a dyn file.

Hello Einar,

screenshot is what I’ve tried so far, to summarize:

1. I need to get all Analytical Floors
2. Read a parameter value (“DL”) from those elements
3. Create a hosted area load with the value “DL” for each element.

I just can not send the parameter values together with the elements to python script. I’m feeling soo noob 😖

At first glance it looks like that example should work, what is the error message you get?

You should move the transaction start outside the loop:

Hi there,  
I moved transaction outside however I get an error stating:

Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed.

I added three nodes, and the python script created the load:
