How to export geometry directly from Grasshopper using IGES file

Hi everyone

I am trying to find a component in Grasshopper that could export directly set of curves using IGES file without having to bake it to Rhino. Is that possible? 

In other words, this component that I want should be able to take Grasshopper geometry as inputs and automatically write an IGES file or STEP file in a specified folder that I want such that the file contain all information about the geometries (coordinates and element connectivities)

Or should it be done by script...?

Please advise.
