How to create smooth curves on text

Using Fusion360 I’m cutting out door numbers which are about 175mm high. I create a sketch and draw some text which I then extrude. The curves on the numbers (e.g. No 8) are a bit chunky. Does anyone know how to make F360 draw the curves smoother, i.e. increase the number of faces in the curves?

Can’t help w/ Fusion360 — when I wanted the best possible text, I found it was most expedient to handle it separately in F-Engrave as a V-carve — I just created the G-code in register w/ the balance of the file, ran the engraving file first, did a tool change, then the other file.
