Create these two commands and it worked for me.

l1=Sequence((r cos(2π i / n + ang), r sin(2π i / n + ang)), i, 0, n, 1)

l2=Sequence(CircularArc((0, 0), Element(l1, 2i - 1), Element(l1, 2i)), i, 1, n / 2, 1)

do you mean Curve(r cos(t + ang), r sin(t + ang), t, 0, 2π) ?

Thank you. This command does work well to rotate the circle with dashed large line.
