The Shell Face command allows you to hollow out individual surfaces if a feature should have a wall thickness other than the shell body.
In the register under Face to Shell
, select the areas to be added to the shell body. Under Face to Pierce you can select an area, if necessary, so that a surface is to be penetrated additionally.
As already described in section 8.2.6.1 "Shell Body", it is again possible to adjust the wall thickness.
