Tom,
I truely believe that "Overhead all" controls the ENTIRE element’s outline as stated. I tested the issue further and I was able to get the footing to correctly display.
The key is the Show on / Link to Stories: setting. If it is set to "Automatic", then it will display as a solid line.
But if it is set to "Own Story Only" AND if the Floor Plan Display setting is set to "Overhead All", then it takes on the line style and pen color defined under Outlines.
While it works fine with composite wall types, as noted earlier, it does not work with the complex profiles.
Hopefully this helps.
