Hi,
I'm under Win2K (french version). When I install Catia V5.R11, the french interface was configured automatically.
Now I would like to switch to english interface.
How to do that please.
Just to say that by default catia will speak the same language as your Windows, unless you specify that in the install (I can remember in R10 that there is something like that).
After the install just go to (as said by vnpenguin) to Tools/Customize (or the equivalent in your language) on the last tab on the right you will be able to change for English, French, German, Italian, Japanese, Simplified chinese or Korean
ps : Votre Francais est vraiment tres bon a tous les deux !!
