This works perfectly, thank you!
The only problem I now face is with the lower floor. I don’t know why. I will attach the file here.

The shaft is exported on Level 01 but not on Ground Floor Level.
The ground floor does not export the shaft:
But the first floor does:
It would be great if you could take a look 
Besides this, everything worked great for this model!
Hi @ketan,
This is a visualization issue in Rhino. The model is exported correctly and I can load it with Grasshopper.
@mingbo, can you check this file and see what’s going on?

@chriswmackey, you might also want to check this case as it doesn’t visualized correctly in the Grasshopper plugin too. The wireframe only component and the mesh-based visualization works but not the other one.
So the issue is that you have some completely invalid Shade geometries in your model that have Zero area:
The honeybee validate model command reveals several other issues:
Thanks! It looks like we need to implement the validate command on the Revit side sooner than later. We can remove those shades from the model.
I think the adjacency issue is happening because of the partial export.
