Back in 2005 before I started working here someone created a giant family table and it has been wrong since. Is there a way to completely break up the family table, and reorganize its structure? I dont want to erase them because they are used in many places, and i want to retain the file history.
For Example:
Original Generic:
Part 1
Part 2
Part 3
Part 4
Part 5
Part 6
Part 7
Goes to
New generic 1:
Part 1
Part 2
New generic 2:
Part 3
Part 4
etc?

Hello all,
We use Creo 2.0 with Windchill 10.1.
I found the answer I was looking for:
SPLITTING UP FAMILY TABLES INTO MULTIPLE TABLES.
(WITH CREO 2.0 AND WINDCHILL 10.1)
THIS PROCESS CAN BE DIVIDED INTO 2 PROCESSES, REMOVING INSTANCES AND ADDING THEM BACK

Do you use Windchill or any PDM software?
Also, are these final assemblies, or are they subassemblies that are used in other assemblies?
I have broken up some family tables, but it is a lot of careful work.
Thanks, Dale
(no PDM software and WF5/Creo)
It's one thing to set instances adrift, but more difficult to divide family tables into new smaller family tables.
I'm pretty sure Pro/E looks at the base Generic to see if the instance is still there, then it looks for a standalone part. I don't think there is a mechanism for it to look in other files to see if the part happens to be in them. You can imagine the confusion if the same item was in multiple family tables.
While you could patch PDM references to get the correct files linked to the new structure and probably have your supplier not support your data after you do so, you still need to modify the assembly files to match.
There's a similar problem with reversing the process - eliminating a standalone model and redirecting requests for it to a family table. So far Pro/E doesn't know to look in all possible family tables to make that substitution when the original part is no longer available.
The option that comes to mind is to prefix all the names with "fix_this_" and create new family tables with interchange groups to the old components.
As I mentioned it is not an easy process.
1. I find that I can make copies of drawings and cad files from the folders themselves. I usually name the copies with something like "ZZZZZ" as the front after the copies have been made (so that way they "fall" to the bottom when sorting a folder).
(e.g. ZZZZZoldname.asm, ZZZZZoldname.dwg)
2. Open the original drawing(s) and from one of the drawing(s) open the generic assembly model.
(e.g. oldname.asm, oldname.dwg)
3. Rename the generic model to the new name chosen. Rename the instances I want to keep (if needed). Rename the drawings (if needed).
(e.g. oldname.asm -> newname.asm, oldname1<oldname>.asm -> newname1<newname>.asm, oldname.dwg->newname.dwg, ....)
4. Delete the instances that are not needed in this family.
(e.g. oldname4<oldname>.asm, oldname5<oldname>.asm)
5. Save the drawings, models, and generic. Then close and erase from memory.
6. In the folder remove the "ZZZZZ"'s from the copies.
7. Go into the "orignal" files and delete the instances now in the new files.
8. Repeat the process as needed.
If the assemblies are a sub componenet, it gets complicated in that you need the models of the parent components open when you are doing the renaming else the connectivity get lost.

Hi Rob,
Thanks for this. It has been very helpful. In the meanwhile a quick question. Let us say we have the following scenario:
Generic
1. Instance_01
2. Instance_02
3. Instance_03
I am splitting the family table like this
Generic 01:
1. Instance_02
2. Instance_03
Generic 02:
1. Instance_01
After the split, when we check in the workspace we see two objects for instance_01 ie. Instance_01 and Instance_01<family table_generic 02). Is this a normal behavior?
thanks
By the way, keep in mind that family tables are:
- A single CAD file
- Multiple Windchill objects, with only the Generic having a Content file
This is why the system always needs to add the Generic to workspace in order to give you any instance.
For an instance to become standalone or part of another Generic, the system has to grab it's data and create a new file. Interesting in these types of things to always closely examine the Content tab of each object in Windchill.
Hello,
I am not worried about any PDM system right now. I would like to understand from CREO point of view alone. So please let me know if it is normal to have same two instances (please refer to my post above) in the workspace after the family table is split.
thanks
You do not want to have files with the same exact name.... Generic's or Instances
Dave
McClinton,
I am not sure if I understand you. Please go through Robin's post of splitting a family table. Also kindly connect it with my post of what I experience after splitting the family table.
For the benefit of you let me post my question again.
I have a generic and three instances attached to the generic through family table. Now I would want to split that family table. I followed the procedure as posted by Robin ie keeping the instances open along with the generic in the session, deleting the instances from the family table, saving a copy of the generic and then redefining the instances ie. using the same name for the instances that are in session. After all these actions when I go into the workspace I see the same two instances. For example I see two parts for instance_01 that was earlier with generic_01 and now moved to generic_02. It exists in the following format.
instance_01
instance_01(family table_generic 02).
My question is, is this a normal behavior?
If you feel that this is not the right way to split the family table, may I ask your suggestion on how to get this done?
thanks
Without having actually gone through this headache-inducing procedure, I suspect that at some point you did a save-as function to break instance01.prt out of its original generic and turn it temporarily into a standalone part. So it seems that this is what remains in your workspace.
So, double-check that instance01.prt isn't used anywhere and then delete it...
Thanks Paul for your inputs. Now that I have sorted out from the CREO side, I need to see how it is going to integrate with the PDM system.
