Linking parts in CATIA: Publication

We can have the same sketch (or parameter, geometry, body,etc) in different parts of the same assembly, that way if we need to change this element, we only need to do it in one place.
Some examples:
1) Diameter of holes, lengths.
2) We maybe want a reference model with all the sketches, and then copy those sketches to different parts.
3) We could have a solid of revolution, that we need to split due to the chosen manufacturing process. And after the split, maybe because of minor features (holes, etc) are not totally simmetric, so we have to define two parts with two drawings. We could be faster if we linked only the common solid, before applying specific features.
In all of those cases we can use the powerful tool in Catia known as Publication.

  1. Step 1: Publicate

    Publicate the element in the part file origin, and copy this element.

    The Sketch is finally publicated.

    We save first the file, and then copy the element publicated in the tree.

  2. Step 2: Paste the element in other part

    We go to destination part file, and right click on the tree:

    Now we paste the element “As a result with link” in the part file destination

    Finally we have the original element linked in our destination file. It will appear down a set named "External References":

  3. Step 3: Bonus 1: Publicate a section of features

    One useful process, is create a sub-body (command “Insert in new”,) and then publicate it. Later we can continue editing the main body without affecting the publicated one. 

  4. Step 4: Bonus 2: Check all the linked parts are loaded

    Sometimes a link can be broken (new versions of the part) or after open CATIA not all the parts can be loaded. We can check (and load) this links here:

    Appear this window, we can click on "Load" if the the status appear as "Document not loaded"

    This tool can be used also in Assemblies.
