Get selected floors analytical model

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…


  • 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

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 :confounded:

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.
Traceback (most recent call last):

Hosted Area Load.rvt (324 KB)
HostedAreaLoad.dyn (6.2 KB)

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