This is may not be a good answer explaining why is the Symbolic Ring not working here, but at least a workaround: froget about symbolic functions and use Python lambda functions instead:

sage: plot3d(lambda x,y: abs(x+I*y),(x,-5,5),(y,-5,5))


This is may not be a good answer explaining why is the Symbolic Ring not working here, but at least a workaround: froget forget about symbolic functions and use Python lambda functions instead:

sage: plot3d(lambda x,y: abs(x+I*y),(x,-5,5),(y,-5,5))
abs(x+I*y), (x,-5,5), (y,-5,5))


or even:

sage: plot3d(lambda x,y: abs(x+I*y), (x,-5,5), (y,-5,5), adaptive=True)
