Model of free form shapes in Revit is still kind of rare in the market nowadays since Revit is not born for this type of geometry, We developed our own customized tools to make this type of model in Revit internally.
This sofa model is nicely curved, clean, pretty small in size, and just for Revit.
Since the model is in CAD-like Solid format so it is a little bit different from the 3D models in mesh and polygons in terms of polygon vertices etc numbers,We recommend rendering this model in Octane render (or Vray etc render engine) which can use proxy to provide more detailed features,The octane render proxy is also provided in https://www.cgtrader.com/3d-models/furniture/sofa/sofa-in-octane-render,which has better material and UV applied
This family can also be rendered directly in Enscape in a Enscape native sofa's looking.
*The model for the people shown in the preview is not included (whish is from third party and just for reference ), if you have any questions please contact the seller.
