Mirroring changes in curve objects
When you mirror changes in curve objects, you edit nodes and have the same edits take place in reverse on corresponding nodes. For example, you can move a node to the right, and its corresponding node moves the same distance to the left.
To mirror changes, you must select two curve objects one of which was created by mirroring the other, or a symmetrical object. For information about mirroring objects, see “Rotating and mirroring objects.” Next, you need to choose whether to mirror changes horizontally (along a vertical line of symmetry) or vertically (along a horizontal line of symmetry). Finally, you need to select the appropriate corresponding nodes so that editing changes are mirrored across the selected objects.
Left: Two corresponding nodes are selected in mirrored curve objects. Right: When the blue control handles are moved, the change is reflected in the corresponding control handles (in red).
