This example creates the maker coin as defined by Angus on the Maker's Muse
|
|
YouTube channel. There are two key features:
|
|
1) the use of DoubleTangentArc to create a smooth transition from the
|
|
central dish to the external arc.
|
|
2) embossing the text into the top of the coin not just as a simple
|
|
extrude but from a projection which results in text with even depth.
