Hello, I am trying to thicken a complex surface; I see in the Help Doc that there should be two useful options in the Thicken Sheet command: "Approximate Offset Surface" and " Show Failure areas" . I would like to use them, but they don't appear in my dialog. According to the Help Doc they should be in the "Setting" section, but I don't have them, I only have the "Remove Gashes" option. Does anyone know why?
Below is a snapshot of my dialog oprions (left) and the Help page description (right).
Thank you in advance
