Learn how to use the Isolate Symmetry command to prevents symmetric constraints from being applied to specific faces, edges, or vertices on a T-Spline body in Fusion.
In the Design workspace, Form contextual environment, select Symmetry > Isolate Symmetry .
The Isolate Symmetry dialog displays.
In the canvas, select faces, edges, or vertices on a T-Spline body.
Click OK.
The faces, edges, and vertices that you selected on the T-Spline body are excluded from any symmetric constraints applied to the body by the Mirror - Internal, Circular - Internal, Mirror - Duplicate, and Circular - Duplicate commands.
