The ‘H’ is a combination of various shapes which were then MERGED HIGHEST to the base relief as a last step.
The ‘O’ and the ‘P’ were created at the same tile as the gears were similar. The ‘O’ gear then got a raised hub with a hole drilled into it by using the merge lowest tool and a zero height relief of that size.
That completed the lettering and I was happy with the result. Then it was on to the border – a simple domed and raised border. I built it as a separate file as well as the rivets, then merged highest.
The gear was the last relief I created. All of the reliefs were then merged highest onto a zero height relief. This made the file ready to tool path and route.
Give the file a try – it’s great fun!
