How to Shell a Sphere in CATIA V5

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.

Only after selecting the shell command and then clicking on OK will the sphere be shelled. Most users tend to
select the surface for shell where the command doesn't work.
