Transferring geometries from Rhino to Grasshopper

New to Grasshopper and Rhino. From the tutorials that I have been watching all of the samples are shown on simple surfaces or simple lofts in Grasshopper with a vase etc. Can you input a complex geometry like a chair into Grasshopper from Rhino or would you have to construct in in Grasshopper? Can you apply surface patterns on these shapes? Sorry if this question seems confusing. What I am trying to find out is what can you input into Grasshopper from Rhino to create a workflow.

Thank you


Yes, probably as a mesh or brep aka polysurface.


You can reference pretty much any geometry type from Rhino in Grasshopper!

Thank you for your prompt reply
