This is what the Properties Pane is for Matt - if there is a defect in the Properties Pane we should rectify that rather than add stuff into the coordinate scroll - I would like to see what you are seeing in terms of speed issues - can you record a video that shows that for me or can we do a GoTo Meeting tomorrow or this week sometime to take a look at that.
Since any object can be included in multiple surfaces or included in multiple corridors as a reference Line or be used as a ref line in a sideslope or included in vertical designs, I feel that its dependencies in a properties pane could be over burdensome - but I would like to know why that is important and how you would use that information as it may be possible to support that somehow if needed.
