Automatically mirrors sketched strokes, either bilaterally or radially.
Check/uncheck this option to turn symmetrical sketching on or off.
Bilateral – Defines an axis (straight line) on the canvas which acts as the “mirror”.
Radial – Defines a number of lines emanating radially from a center point. They divide the canvas into a number of sections, each mirroring everything drawn in any of the other sections.
Specifies the number of sections defined by the radial lines when Symmetry Type is set to Radial.
