Help me with Rhino and Revit

Job ID: 34116963

Budget: $10 – $30 USD

I used Grasshopper and baked few layers into Rhino- elevator, faced and construction. In order to load the building to Revit I uploaded the different layers, as masses (families), each layer apart.
The problem is that it seems like the shape of the building make it hard for Revit to allow me to make glass facades for example (it seems like layer on layer), same as to define walls.
Maybe there’s other way to transform the building into Revit, but I couldn’t succeed. Also I would prefer to upload the whole building and not three times (divided to different layers), but still, I want Revit to ‘realise’ the three layers, so that I can control each of them (not as one mass).
Can you help me to solve that?
