What is the use of "publishing command" in Catia?
The use of Publishing is to get an Association between TWO or more CatParts. Example: Profil-A.CatPart has a flange. You can publish the surface of the flange in Profil-A. you have another Different-Profil-B.CatPart with a mating flange. Now you can use the published flange in Part B. If you modify the flange in Part A it will also change in Part B.
I think I will make an tutorial soon at
