https://community.wolfram.com/groups/-/m/t/1567764
Hello.
Let's say we have circle. We cut it to 4 'triangles' but longest hand is perfect arc. I want to write some letters on this arc but rotate it to be horizontal always.
In other words, how to make clock face with horizontal numbers. It can be any hour, so can be 12-3-6-9, but can be 1-4-7-11 etc.
Thanks for suggestions.John Cosmic2018-12-08T00:16:55Z
