Bruce
Thanks for your time on the phone today - awesome to meet you and get this discussion underway. For anyone else watching this thread I have a question.
What Bruce is asking for is the ability to create a Site Improvement Legend on a Drawing Submittal (a bit like the Cut Fill Map Legend but different) that captures all of the Site Improvements applied in a Takeoff / Site Model and creates a Legend Block that can be placed directly on a Drawing Sheet or Dynaviewed to a drawing sheet that shows something like this for each Site Improvement used. He wants that to be Dynamically updated as Site Improvement Material Layer Thicknesses change or if additional material Layers are added or if new Site Improvement Areas are added after the Site Improvement Legend is created.

The Squares would be filled with the applied site improvement color (in the Map of the project)
The Site Improvement Name followed by the Site Improvement Layers and Layer Thicknesses placed automatically using Smart Text that updates or can be refreshed whenever changes have been made.
Do others out there have the same need - I think it is a great idea / request and would like to gauge the interest from others out there doing similar work.
Bruce's company does Site Engineering Design for their clients and this is a deliverable, however I could also see this as a Drawing that I would give a Foreman on site to know what was expected in different areas of the job.
Great to hear a British accent again Bruce! - appreciate your time and assistance in helping me to understand the requirement
