Question

Different Revision for Each drawing Sheet?

Using Pro/Intralink 9.1 and Wildfire 4

In the process of migrating some legacy data into Pro/E & Pro/I.
Migrated data needs to be the "same" from a configuration management
perspective.

Has anyone tried to manage multi-sheet drawings where the revisions of
each drawing sheet are independent?

No but I've seen it done (not in Windchill). I think I even saw CMII
Institute doing that for their docs. I could be wrong but this seems
like a hold over from a time a paper, hand drawings. On the surface, it
seems efficient to be able to revise only the sheet that has changed,
saving time and you know where the changes are. In an electronic
system, it becomes problematic since what is the revision of the whole
drawing? Or the part that the drawing specifies? I think most places
stopped this practice long okay but that is just what I've seen.

This goes against every standard I have ever seen or heard of.


If this has been your general practice in the past I don't think you will be able to accomplish this in Pro/Intralink.


It may be time to revise your process & procedures to conform with sime industry standard.

We did this at another company, but they were only using PDMLink as a CAD document vault. Nothing was ever released in PDMLink.
I went to engineering management and we started making all sheets the same revision and using the release procedures in PDMLink.
My argument was that ALL sheets are contained in a single file, ALL sheets MUST be at the same revision level for tracking.
IT even had TeamCenter, which was the official release vault, programmed with individual sheet revisions even though we were uploading a single revision Pro/E file for the design.
Some of this was carried over from the old manual drawing days and some because the AutoCAD users were doing each sheet in a separate file.
The company did aircraft modifications on military aircraft so most of the customer drawings were very old hand drawings.

Thank you,

Hello Andrew
We used to have that system years ago, with manual drawings before ProE, but when we went to ProE we unified the revision in the bills of materials (still different from the revision of the actual drawing). In time we also unified revision of drawing and bills of materials.
My suggestion is you go to one revision for all. Much easier to manage.

Best regards

Daniel García

Same here. We use to use a different revision level for each sheet of a
drawing, and when we went to Pro/E, we were basically forced to have one
revision level for the whole drawing, because it's one file.



At the end of the day, this really makes the most sense.

Thanks to all that replied.


Consensus is you can't do this without managing each sheet as a separate drawing. Makes no sense in a parametric CAD system.


Further discussions with our configuration management group is that they don't / can't manage individual sheet revisions any more, either. Recommendation is to pick the latest revision of each of the sheets and make it the Pro/Intralink CAD Document revision. If the drawing ever gets revised, they will include the change in revision scheme with the documentation.

We looked at this exactly oppositely. It makes no sense to have different
revision levels on different sheets of the same drawing that carry the
same number. If each sheet is a different number, then isn't it
technically a different part number? If sheet 1 is rev C, sheet 2 is rev
E, and sheet 3 is rev A, then what is the revision level of the drawing?
C? E? or A? How can one part number have three different revisions?



To me, it seems like / feels like, Intralink and Windchill are doing this
properly, by requiring that a FILE have only one revision level.



Other's mileage may vary.

You might be able to come up with a way to get around this if you had wiggle room in your requirements....you could create parameters called SHEET_1_REV, SHEET_2_REV, etc. and give each one a unique value and display them on the corresponding sheet. But this is not the same thing as managing sheets as individual objects.
You can technically nsert one drawing into another drawing using the insert - shared data function. So you would have individual sheet drawings with their own rev and then one top level that combines the others. Not sure if that's what you're looking for or not. I haven't used it since I don't have this need....but I remember playing around with it once.

If we are talking about EPMDocument we should not be talking about files.


The file is the content of the EPMDocument, I can revise my EPMDocument without making any changes to my file.


The revision level is better controlled automatically by the system. If you modify the file, it modifies the EPMDocument but not necessary otherway round.


I perfectly agree that one piece of information must have its own number and revision.


For instance, when you have a product and its CAD model which is therefore unique for that product. It will have its revision. If you create 3 2D representations of that CAD model for different purposes (2 different manufacturing sites requiring different units, language, information, and a drawing for your customer's approval), how can you have for the 4 pieces of information the same revision ?


The 2nd 2D production drawings could have been created only when the product went to its 3rd level of revision ?



I also agree with many of you that multi sheets drawings should have the same revision on each sheet. It is only one file.. one EPMDocument. Now do you put the revision of the your model or of your drawing on it ?


We currently put both for the reason explained above. Technically we tell manufacture or suppliers. Make Product 123 Rev D according to 2D representation 456 Rev B



Fortunately for us, Windchill has this flexibility !!!
