Thank you for your answer. I'm trying to fit the veneer to the purlins I put on the scissors, there are scissor consoles, even if I add an element to the last gap, it does not exceed the end point of the scissors. A second problem, which I am not sure about, is how do we define the load in the coating? When we select one of the available skins in the library, is the overlay load defined automatically? Is there a need to add snow load next to the live load? Is a definition correct as I have shown in the picture below? The project is attached:
