Hey AnBe
Welcome to the Speckle! Feel free to Introduce Yourself if you feel like it🖖!
Sorry for the late reply!
Speckle only supports flat, editable floors. For sloped ones, Speckle supports only DirectShape (you can map the category) or Freeform. You might also want to consider using the topography element.
Could you please share the reason you prefer to use floors for creating streets? Additionally, could you provide more details about your workflow?
I leave this video here as a reference for the mapping.
