#### 8.1.7 EllipticArc

• EllipticArc( <B>, <A>, <C>, <Rx>, <Ry> [, direction] ).
• Description: draw an elliptic arc with $Ox$ and $Oy$ axes and center <A>, $Ox$ radius is <Rx>, $Oy$ radius is <Ry>. The arc is drawn from the line $\left(AB\right)$ until the line $\left(AC\right)$. If the optional argument <direction> is $1$ (default value) then the arc is drawn counterclockwise, and clockwise if its vaue is $-1$.

EllipticArc Command

Note: for a circle arc, using equals values for <Rx> and <Ry> is a solution, but it is easier to use the macro Arc that is replacing the Arc arc command of the old version.
