Creating a shell
You can create a shell as connected offset patches and selected original patches. Sheet metal parts can be created initially as shells. See Offset Patches – Thick Shells. In this example, the patches for offset are selected by the option “All except detected”. Otherwise, you have to click each patch separately.
