I quote : "A solid is expected to contain a single shell that describes its external boundary. If there are two or more shells, it's considered to be a solid with voids".
The solids I import from step files does not seem to have this property. A complex solid with several holes only have one shell.
I also tried the method descibed her : https://dev.opencascade.org/content/how-get-external-and-internal-boundary-holes-edges-mesh-face, but her i get 0 wires.
What am i missing and whar can I do to extract the external boundary of a shape ?
