Hummingbird export to Revit fail

Hi everyone,

I am currently exploring Rhino to Revit Interoperability. I am using Lunchbox to create desired geometry in Grasshopper, and planning to export it to Revit via Hummingbird.

I have attached a photo of my geometry below. Which Hummingbird component should i use to generate the csv file required by rhino? 

Note that i am currently using Loft (in hummingbird) component. After i import it to revit, it says i have too many points in one place. Cull wont work. 

If i need to use Mass falimilies or Families instead, which Family/Family Name/Type does it belong to?

Any thoughts and advise will be highly appreciated. Thanks!
