how to model the part attached with this question / in solidworks
how to pattern the dome like feature along the curve in both direction ?
any type of idea will be appreciated
Your question involves a procedure that seems difficult to achieve. I would have said a lot: how to obtain a relief with a spherical shape! I think it would be easier to proceed with the surface before combining the elements in volume. See: Jumping from one surface to another. Project a patterned sketch on a spherical surface and offset another surface with the same projected sketch. Then sketch 3D faces by drawing segments joining points from one face to the other. After that you will have to sew and thicken this 3d surface.
