I'm trying for a few hours to convert an enclosed surface into a solid body but it does not make the command. I manage to make the knit of the surfaces and the check box with the "create solid" appears. I select that check box and the command aparently do what it's supposed to do, however, a solid body does not appear on the feature tree and it remains, hollow.
If anyone know how to solve the problem, please report your experience.
Thanks in advance,
