However, Spatial Element Boundary works. Which then, I will have to recreate using Boundary Surfaces and culling by area when I have a lot of separated area lines.
I would like to add Areas in revit don’t have a heights like rooms/spaces hence the word “Area”… so it is a 2D boundary that’s why you can’t use spatial element geometry (volume).
As for your query…you can directly cast/connect your area element to a GH surface component and it will output a surface as you need. I also don’t believe there might be a case where a Revit area wouldn’t output a valid correct surface using boundary surface or casting to a surface unless it is not properly enclosed in Revit. (Please feel free to correct me / provide a sample with such a case if you faced any so we can further assist)
