advice needed on how to structure a project

Hi all,



This is a request for your thoughts on how I should deal with the re-use of
an assembly.



First of all, I am on Creo 2.0 and not using any PDM. Lotsa fun.



Here's the story.



I have a machine that was made a long time ago (designed in Pro/E by me in
2004.) This machine is a tool for assembling a gizmo. The hardware has
been deemed obsolete due mostly to the gizmo being outdated. Sure enough, a
new and improved gizmo exists - for which I designed a new machine to
assemble it. But the old gizmo assembly machine is sitting on the shelf and
is very similar to the new gizmo. Sales are up and production needs to
increase. Rather than spend the money on additional new machines, I have
been given the task to convert the old gizmo assembly machine to work for
the new gizmo. Of course, I want to change as little of the components as
possible and even modify existing components if possible.



There are probably ~50 machined components and a small pile of OEM hardware.
Certainly manageable without PDM, but I need to be concerned with
documentation in the end.



The challenge is just keeping everything straight between.



Reused old parts

Reused new parts

Modified old parts

Potentially new new parts.



If I make a change to an existing part - old or new, I need to be sure that
I document that change - resulting in a new part. But I don't want to
simply "save as" to the entire assembly with new names for everything.



I imagine creating a backup copy of both Old and New assemblies into a
folder, creating a NewNew assembly and manually assembling the components as
needed. This will hopefully allow me to track what I need to change - and
upon changing, rename. I know there is a utility that exists inside Pro
that compares geometry and / or features. Is this a decent tool that I
should use for this task? I've never actually used it. Are there other
workflows that will make this task less confusing? Anything to watchout for
so I don't get burned?



Thanks for reading - your thoughts are welcome!



-Nate

Nate,


You can probable guess my answer....go old school. Deal with each part methodically and make 100% they are correct for your new purpose. Change the color of each part once you addressed it and keep moving until you are done. My opinion is relying on the automatic with so much to ensure is a bit risky.
