We have calculated numerically the change in the NMR signal of rotating superfluid He-3-B induced by the presence of one spin-mass vortex. The NMR line shape is determined from the equilibrium distribution of the order-parameter axis (n) over cap (r). Depending on the external conditions, two textures of different symmetry and with clearly distinguishable NMR behavior are obtained. One of these agrees with published NMR measurements, the other has not been reported earlier. The methods are discussed by which the texture transition and the new reflection-symmetric texture could be observed experimentally.
