Isolate Symmetry reference
The Isolate Symmetry tool prevents symmetric constraints from being applied to specific faces, edges, or vertices on a T-Spline body in Fusion.
Design > Form > Symmetry > Isolate Symmetry
The Isolate Symmetry tool turns off symmetry for the selected faces. The isolated faces display in red until symmetry is cleared for the body.
