|···||Alt+C, F, V||Vector -> Mirror Vertically|
The Mirror Vertically command creates a vertical mirror image of the selected vector entities.
Select one or more vector entities using the Vector Select command, then activate the Mirror Vertically command. Set one point to act as a reference point, and a second point to establish the location of the mirrored copy.
After the mirror copy has been placed, the new copy becomes the new selection.
