I first did a quick vector trace of the sign and lettering.
Lastly I added a bent rectangular vector around the sign border and lettering.
The border vector was selected and using the flat relief tool I created a flat relief.
This relief was then modified using dome tool using the bent rectangular vector as a mask.
In the same fashion I created a flat relief of the entering border and then modified it using the bent rectangular shape to dome it up to match the sign background.
The steel bands were then created and modified in similar fashion. These were combined with the sign background reliefs.
Once the bands and sign background was united into one relief I then combined the lettering border with the sign background using the merged highest command.
Then I modified this relief by adding the second raised border.
Lastly the raised and domed lettering was added to the relief.
The sign face was now ready for tool patching and routing from 2" thick - 30 lb Precision Board.
Stay tuned for the next processes on this sign.
