This may sound weird, but how do you shell a sphere in CATIA? First, you need a sphere. Model a sphere as a solid using the shaft command (sketch Semicircle D of __mm diameter) or use the shell command in GSD. Or you can make a sphere in CATIA using a CATScript macro. Then, to shell the sphere geometry:
- Shell Command. Add a value in Default Inside Thickness eg: 2mm
- Select the sphere surface in " Face To Remove".
- Again Select the same surface in "Other Thickness Faces"
- Click OK.
select the surface for shell where the command doesn't work.
