How can I select single face ?
Hi everyone, I have a problem about shell command in Catia v5. Because when I select a face that ı wanna remove, catia automatically selects tangent faces so I receive an error about it.
In siemens Nx, you can choose if you wanna select single face or tangent faces while selecting. Is there any option in Catia like this ? I don't want catia to select tangent faces automatically.
For example I wanna select only bottom face but it automatically selects tangent faces when I click on bottom face. (I attached a screenshot)
Thanks...

The dirty way is to make a sharp corner there. Like add a pocket some distance and remove all the faces inside the pocket you created. Or just shell the whole thing and cut out with a pocket to reach the inside. Some remove face to clean the result where the cut is not along the angled walls. But i't really not advisable to do it like so.
Other way is to ditch the shell approach and use thick surface instead. Extract the surfaces of your solid in GSD and thick each surface the way you want.
Also it gives much more control if you design each surface independetly in GSD in first place. And not going to closed volume-shell, but thick surface on each surface. (or just join the surfaces you want to make a single thick surface command)
So keep in mind thick surface is a much better option to design thin wall stuff than shell. Also it can make internal dividers which shell can't. Also design each surface instead of solid is way better approach as it's more mathematically sound (as geometrical sets are non-oredered, while bodys with hybrid, are and can create havok in the part later on as oposed to a non-oredered geometrical set or nonordered body)
