Multiple Versions

Anonymous — Sat, 18 Sep 2010 03:19:04 GMT

Hello,
I recently duplicated a library part called Tube 10.gsm
in the hard drive directory and changed it's name to Tube.gsm.
(Please note that this is in AC 10, not AC 12 where names are ignored.)
I then opened the Tube.gsm in Archicad's GDL editing environment
and deleted a few parameters, added some parameters, altered the
2D and 3D scripts and saved. I used Tube.gsm in a project but every
time I open the project Archicad says I have "Multiple Versions" of Tube .
Clearly, they are not the same lib part because of the editing I have done
and this is reflected in the differing GUIDs listed in the library loading report.
See attached which is the loading report I get when I open the project.

What do I have to do to convince Archicad that the two lib parts are not
"Multiple versions" but different lib parts ?
Thank you,
Peter Devlin

You should open the object in AC and check "create a new object", when using "saving as". A new GUI will be created and no multiple versions should be named.

You can use the same name. Reload libraries afterwards.

Hello Frank,
Thanks for posting back.
In AC 10 there is no "create a new object" only save and save as.
Notice in the library loading report Tube 10 and Tube have different GUIDs
so I don't understand why AC thinks they are "Multiple Versions".
AC says "Multiple Versions" not "Duplicates". I do not understand
the difference.
Thanks,
Peter Devlin

Force AC to create a unique copy for you:

Open Tube 10.
Check the "template" box near the top.
Save. Magically it is a save as even though it still says save. (go figure)
Save with new name in a directory of choice.
Place new object "Tube".
Now edit this unique object.

There is no "geometric shape" library subtype.
"Template" allows any part to be an ersatz "subtype" for new parts.

Hello Frank and Snap,
I did an experiment. I opened a new project from our office template,
inserted an instance of "Tube" and an instance of "Tube 10", and
saved the project. I closed the project and quit AC.
I launched AC, opened the project and no library loading report
about "Multiple Versions" appeared. I can only conclude that
the project that displays the library loading report is somehow
corrupted. I think I will try a forward merge and see if that gets
rid of the loading report.

If the file in question is corrupted, it is the first I have ever seen in AC.
Thanks,
Peter Devlin

I had more often "corrupted" files. But AC mentioned that itself and fixed it in a more or less data-loss way.

Try to open your project without the old TUBE-object in load library (move temporarily in an external folder).

Now have a look on the fat points and see which objects are missing indeed.

I do not think, that your project is corrupted, I think, that reason is found in the library parts or handling.

Another try: Open it in AC14. There you can find better informations about objects, which are duplicated in library, in plan and of placed or unplaced objects.

If you open the objects, the complete GUID, found in objects subtype has to be different. See GUID

Hello Frank,
I went to the ArchicadWiki article that you referenced and
found the following about Multiple Versions.

Library Loading Report
In particular, there are 4 different categories:
1. Missing
2. Duplicates (If in any case there is a clash of GUIDs between Library Parts within loaded libraries, the Library Loading Report will notify you with a Duplicate Library Part alert.)
3. Duplicate Names (Only the names are identical)
4. Multiple Versions (Only the Main ID is the same, but the Revision ID not)

7. more about GUID
short summary:
The GUID consists of two parts, each 36 characters long. The first 36 characters represent the Main ID and the last 36 characters represent the Revision ID.
The first part of the GUID will change only after opening the Library Part and using the Save As command.
The second part of the GUID will change after opening the Library Part and using the Save command.
When ArchiCAD needs to resolve a Library Part reference it will first do a search on the whole GUID.
If it does not find any similar element it will look for any matches of the first portion of the GUID in the Library.
If it can not find any matches there either, it will not search further.

I did a "Save As" twice but the "Main ID did not change as promised in
article.
Thanks,
Peter Devlin

Hello Peter,

I do not know, where's the problem, because I do not run AC10 anymore. AC 13+ provides a "create new object"-button.

In your case I would create a new object, of new subtype and would merge code and header by the "GDL Converter tool". I know it should go a smarter way, but I can't figuer out from here.

Sorry.

Did you try the "template" button?
Works like a charm in 10, no error messages.
You'll have the complete object as basis for your mods.

If you now are dealing with the file and can't get rid of
the error message. Delete the offending placements of the object.
Then proceed with "Template" option as described in previous post.

Seriously doubt you have corrupted file, just embedded garbage.
Get rid of the junk, you should be fine.

F. Beister: There is no Geometric Shape subtype in AC10. You have to use the template button.
Note - the 'template' button is misnamed ~ 'template' is a 'save as' function.

Hello Snap,
I tried your suggestion about the "Template" button but no luck.
The main ID did not change.

I just discovered something interesting about GUIDs.
If you open a lib part and click on the "Select Subtype" button
you will see at the bottom of the window what purports to be
the GUID for the object. If you open another lib part and check
it's GUID it will be identical to the first lib parts GUID.
I did this with two lib parts I have and a new untitled lib part.
So it seems that what is displayed in the "Select Subtype" window
is not the true GUID for the lib part.

From the "Select Subtype" window GUIDs for three different library parts
Untitled {103E8D2C-8230-42E1-9597-46F84CCE28C0}-{309C5AC7-1F49-4A4B-BB16-985704D694EB}
Tube {103E8D2C-8230-42E1-9597-46F84CCE28C0}-{309C5AC7-1F49-4A4B-BB16-985704D694EB}
Low Wall {103E8D2C-8230-42E1-9597-46F84CCE28C0}-{309C5AC7-1F49-4A4B-BB16-985704D694EB}

From the Library Loading Report of an AC project
Tube 10 {67E91165-7433-448A-976A-F6B7D82B87C6}-{E42B4E88-5399-C142-92AD-DCD3A66377E6}
Tube {67E91165-7433-448A-976A-F6B7D82B87C6}-{D2D6BDE7-BD5E-9C46-9789-9041D1E42981}

I really don't know what to make of this. Comments anyone ?
Is there a way of finding out the true GUID for a library part ?
Thanks,
Peter Devlin

Re: Multiple Versions

Frank Beister — Wed, 22 Sep 2010 06:15:27 GMT

The GUID has come with AC 8? 9? 10? If the object is older AC will use a generic GUID, I guess.

As mentioned in the wiki: The first part is a global and the second part a subversion number of the object.

So your Tube object is not really a new one, but a subversion of the original. Like you would have "Tube10" and "Tube 11" in one project. For that GS created the migration libraries.

Try to save your object by a new subtype and switch back and save again. Maybe this creates a new GUID.

To see the true GUID of an object you need to "Open object by subtype".
It shows in the dialogue box before you actually open the object.

I am not sure exactly what the GUID in the object "select subtype" dialogue actually represents.

There was a post a couple of years ago that touched on this.
Crops up around about the 9th or 10th post.

I am pretty sure this is showing the GUID for the subtype (which is a type of library part) rather than the object.

Hello Frank,
I did change the subtype from "geometric shape" to "model element"
but the GUID did not change.
Thanks,

Hello Barry,
You are right. You have to "Open object by subtype" to get the true GUID.
Thank you,

Hello Frank, Barry, David, and Snap,
I started over again. I opened "Tube 10", saved as "Tub2" so I could
copy the changes in the parameter list and the code without replacing
the "Tube object. Everything went well and was able to get rid of
the Library report error about "Multiple Versions" in the problem project.
Curiously, AC substituted Tube 10 in the project rather than the new
Tube object. Yes, I can see the logic. I replaced the Tube 10 objects
with the new Tube object and all is well.

What is the strangest mystery to me is that if AC checks for
"Multiple Versions" then why does it not report "Multiple Versions"
in other projects that have the identical loaded libraries including
a new project opened from a template file with identical loaded libraries.

I much appreciate all of you guys help. Thank you.
I have learned more about this program with your help.
Thanks,
Peter Devlin

I'm sure I've heard of developers calling objects by GUID, inside other objects to work around (or with?) this issue. That way the GUID stays the same always and they just change the reference to match the new GUID.

Maybe that's old news? Never tried it myself.

Cheers,
Link.

Hello Link,
It is good to hear from you.
I have not heard of calling an object using only it's GUID.
I checked in the AC 12 GDL manual and every reference to
macro calls stated one must use the objects name.
I may have missed something. I may just try it to see if it works.
Thanks,
Peter Devlin

I have seen today, that the element info palette offers GUID too.
