The files we use for 3D printing, STL etc. use triangles to define the geometry and arcs are built from a number of line segments. This makes for some large G-code files and affects surface finish.
Slic3r used to have an experimental option to convert line segments to arc, but that has been abandoned at the moment. Following a recent topic here, I remembered seeing a conversion utility;

Nice hint Paul!
Worth giving it a try…
