Collaborative hub has broken my drawing title blocks and forced shared part numbers

[Luke_AU]

Recent fusion updates have forced collaborative hub editing upon me and now part numbers are date time stamps for the top-level assembly in hybrid designs. I have drawing templates set up that put the part number and name in the title block automatically, but now there are being populated with a date time stamp like 2026-05-21-16-18-00-150 for the part number and the name of the first sub-component if the assembly has only one sub-component (used to name the drawing per the selected top-level assembly name automatically). 

Further, if part number wasn't specified, it used to use the part name. Now it is doing some shared part thing. Does this mean I have to have unique part names for each and every part across my hub / storage?

Once again, a lack of notification / documentation from Fusion ahead of update which breaks things and ruins my day with troubleshooting, when I would like to be drawing and modelling.

Anyone know how to roll back to old behaviour regarding part names and numbers?

Hi Luke,

Sorry for the disruption.

Collaborative Experience hub migration is one-way and there is no rollback.

Fusion auto-generates a unique part number when no part number is set. When the same part numbers are assigned to multiple parts, they become part of a Part Number Group (PNG).

Refer to: https://help.autodesk.com/view/fusion360/ENU/?guid=FSN-SHARED-PART-NUMBERS

Refer to the pages below in case you wish to remove parts from a Part Number Group(PNG):

With only one unsuppressed top-level child, Fusion may use that component’s Part Name and Part number instead of the root. This is existing behavior in drawings and is not specific to the collaborative experience.

Hope this helps.

@Luke_AU regarding notifications for this update, your hub admin would have received an email 2 weeks prior to the update. This email contains a link to this support page for more information on managing this update. A notification also appears in the Fusion desktop client 3 days prior to the scheduled update for all Fusion users. I'm not sure what else we could have done to notify your team of the update. Perhaps you have some ideas?

I hope you have had a chance to explore the new capabilities that your hub now has. Please feel free to post again with any questions.

@shainendran.vanparambil thanks for answering my question and confirming there is no way back. Also thanks for the useful links regarding how to work with and remove shared part numbers.

@emily.caulfield to answer your question, I think not forcing these changes on users or giving greater time to adapt would be an improvement. I also think that it was not highlighted what impact this would have on users existing drawings workflow (e.g. I have a part number and name in the title block of each drawing sheet which has now been muddled through forced shared part numbers). I seem to spend a lot more time lately with fusion updates having to re-learn or changing my workflow to suit the new updates.

Hi Emily,

I am a one person operation. I do my own design and fabrication. The Autodesk emails to which you refer and the notification in Fusion really did not explain the impact of Collaborative Hub nor the alternative for a simple operation like mine. 

The designs in my Hub are all messed up now as far as any history. Every time I simply look at a design, it is stamped as "Modified" with the current date. I have Automatic Save On Close disabled (for years). The only saving grace so far is that I have not lost my designs. But any sense of history or design activity is lost because whenever I touch anything in the Web Hub view or the desktop view it is "Modified" as of "Now".

For example I created a design for a handrail. I wanted to use the basic overall dimensions for a second design. So I make a copy of Handrail_1 and named it Handrail_2. Now Handrail_1 has its internal name Handrail_2.

I never needed this part numbering. It's made a mess of my Hub.

Unfortunately Autodesk said:

Is there a way that I can opt out?

CE is an important step toward making Fusion a platform for the future; opt-out is not available.

So how about a way to disable automatic creation of shared part number the same way one can disable "Automatic Save On Close" to avoid saving meaningless changes like when one rotates a part in the viewer without actually editing any sketches, dimensions or anything.

I have the same issue. The workflow in my hub relies heavily on copying and modifying existing, well-developed models. Certain property boxes are used to call out specific information on drawings and to create CSV reports for downstream production subcontractors.

Now, it's all messed up. It seems we can still follow our workflow, but creating shared part numbers, as well as sharing other properties between copies, is causing a lot of trouble. First of all, it's slow and unstable. Ungrouping parts from a shared part number group takes too long.

We need to have the option to turn off the shared part number by default. This might be a good and important change for Fusion in general, but for now, please give us an option to choose whether to share the part number or not when making a copy.
