The conversion from a Revit face to a BHoM one in https://github.com/BHoM/Revit_Toolkit/blob/develop/Revit_Core_Engine/Convert/Geometry/FromRevit/Surface.cs involves finding the main external curve loop of that face. I have a tool that wants to use this extraction logic without calling FromRevit(this PlanarFace face) because List<ICurve> internalBoundaries = crvLoops.Where(x => x != externalLoop).Select(x => x.FromRevit() as ICurve).ToList(); can be slow on large datasets.
Let's move this external loop extraction logic to its own method.
