The first step was to create the flat relief. I made it 0.8″ thick
The oval top was then dropped into this relief by using the subtract tool.
Then I added the next layer of lettering border.
The lettering was created using the bevel tool and I used the constant height option so the tops of the letters were all the same no matter how thick the lettering stroke.
With the body of the sign complete it was time to make the mortar and pestal. I first recreated the curves of the bowl.
I then created a mesh using the revolve tool.
I created the vectors in the same fashion for the mortar and then created a mesh of that piece in the same fashion.
I then created a zero height relief and merged (highest) the meshed to it.
I then squished the bowl vertically to 3.8″ using the precision input tools. I made sure the proportional box was unchecked so it only altered the thickness of the piece.
Then I used the slice tool to create two slices that would each fit in a 2″ thick piece of Precision Board.
