When the segmentation model identifies a feature, but there is no resultant mesh created for the feature we get a vague message "No features processed"

So far, we see that this edge case occurs in the following way:

1. Enhanced-mode (mesh), feature class sidewalk: Only accepts floor-type mesh polygons. If the model only identified some non-floor polygons as sidewalk, there is no resultant mesh formed. There should be a better message for such an issue.
