I'm working on a non-traditional corridor - a looping transit bus site. The corridor follows a grade around the outer edge of the lot and will be combined with a corridor of the entrance splitter island to complete the model. As the design has been refined, I've had to revise the profile and also add components for sidewalks and then a number of horizontal point controls. Between the revised profile, re-synchronizing of revised templates and adding of point controls, a number of orphaned components have begun appearing in my model. One represents a segment of sidewalk with no point control but others seem to represent the entire corridor depicting the corridor before and after the profile edit.
Nothing I have tried has removed these orphaned components. And they seem to be unavailable for deletion.
