Hello, all, I had an error when I try to use the Customed EP construction which had been written to the construction library. It said “layer_1 is not a valid material name/definition.Create the material first and try again”. I checked the relevant topic, I updated my components and try again, it still did not work. It might be a very basic problem, but I do not know how to solve it .Could anyone help me to fix it ?
Many thanks.
