Hi Pilou.
A small rectangle to the side is one of the profiles that is used to form the pipe. I made him visible. Depending on the selected curve, it will be located in different places. This is a method that moves the "pipe profile" away from the "guides" to avoid conflicts. The mechanism of pipe construction consists of creating solid bodies using profiles and guides, and then the body that is inside is subtracted from the one in which it is located.
