Generated code has no arcs G2 and G3

the generated code has no arcs (gcode G2 & G3), the arcs are a sequence of small straight lines in thousandths of a mm, some machines can’t handle this well. Is it possible that the code is generated with arcs and perhaps with less decimal places example 1/100mm?
example gcode two small 10mm diameter circles
