There was a error calculating the Building Coverage Area of your model. This usually means that there were some irregular geometry found above ground level. \
Please refer to [Rhino Geometry Error](/explorations/start-exploration/geometry-processing-errors/rhino-geometry-error.md) or [Malformed Rhino Geometry Error](/explorations/start-exploration/geometry-processing-errors/malformed-rhino-geometry-error.md) for trouble shooting.
