I also noticed in your first picture that Model Type is set to Reinforcement. You can then also create a new material in engineering data that has the material properties (Modulus, Poissons, and biliniear isotropic hardening) that are in your script and apply that material to the links You can set Model Type to Link/Truss and this acheives the same thing as specifying LINK180. Your command snippet is nothing but changing the element type to links, and then specifying a material property.
