Hi Sonia,
Have you seen this post? Dynamo not reading Rhino geometry It seems it works with Rhino 5 and Dynamo 1.3 only. You may try with MantisShrimps.
I’ll suggest you also have a look Speckle (https://speckle.works/log/speckle-guide/ Here’s a list of object implemented https://github.com/speckleworks/SpeckleDynamo/issues/10) or RhinoInside Revit (https://github.com/mcneel/rhino.inside/tree/master/Autodesk/Revit) as they are the most up to date solutions.
Ciao
Giovanni
