To perform a mirror, simply click that shape you wish to mirror. Nel menu che compare a destra, fare clic su "Operazioni"’ tab. If you wish to perform a horizontal mirror (vale a dire. about an imaginary horizontal line that passes through the centroid), then click ‘True’ under ‘Mirror via z-axis’.
Allo stesso modo, if you wish to perform a vertical mirror (vale a dire. about an imaginary vertical line that passes through the centroid), then click ‘True’ under ‘Mirror via y-axis’.
