Coherent control of electronic ring currents enables the steering of opto-magnetic responses on femtosecond timescales. However, most existing schemes confine these currents to the molecular plane, effectively constraining the electronic angular momentum (EAM) vector to a fixed direction. Here, we demonstrate three-dimensional control of the time-dependent EAM in benzene. By engineering a coherent superposition involving the ground state and three dipole-allowed excited states within the 1E1u(X,Y) and 1A2u(Z) manifolds, we show that both the magnitude and spatial orientation of the electronic flux and EAM vector,(t), can be continuously steered. We identify three characteristic dynamical regimes: (i) steady axial alignment, (ii) single-axis reversal, and (iii) conical precession of (t). These predictions are corroborated by dissipative quantum dynamics simulations using the Lindblad master equation. Our findings establish that coherence across multiple electronic states unlocks controllable degrees of freedom for the EAM vector, demonstrating proof-of-principle 3D opto-magnetic sculpting in benzene and suggesting possible criteria for identifying other candidate polyatomic systems.
