Ultimaker
"Reload All Models" only reloads one model
Cura Version
5.7.1
Operating System
Windows 11
Printer
Creality Ender 3 Pro
Reproduction steps
- Load a model
- Right click on the model and select "Multiply Selected" and make 3 copies
- In another program, save an updated version of the model. Or in the file system, delete the model and rename another to have the same name.
- In Cura, from the "File" menu select "Reload All Models"
Actual results
Only 1 model is updated.
Expected results
All 4 models are updated.

Thanks for the report. It appears (to me) that when you multiply the model and Cura assigns a unique name to each copy by appending "(nr)" to each name, that only the model with the original name ("x.stl" in your project) is acknowledged as being the same model. So x.stl(1), x.stl(2), etc. don't get altered in the Cura scene because of the different name. I think that makes sense, but whether or not that is actually what's happening might be incorrect.
Someone from the Cura team will take a look.
When you multiply or duplicate a model, it creates a copy at that exact moment with all the per model settings. However, the newly generated copies don't have any reference to the original STL that was opened, so changing the original STL will not affect them when reloading all models since they only inherited from the original at the moment of being copied. I understand what you're trying to do here but using the multiply as a template system is not part of the multiply function so I suggest changing this to a feature request as that seems more in line.
What you guys are saying makes sense except for one thing: this used to work. I've done this literally dozens of times in the past.
@gsangermano I'll add a ticket for investigation.
Internal reference: CURA-11905
This did work as described (all models updated) in 4.13.1. Checking 5.8.0 only the original model updates.
4.13.1
5.8.0 Only the original model (in the middle) updates.
@GregValiant Tracked the issue to switch between 5.6 to 5.7 Originally the assumption was the change we did to add the copy paste function (Cura 5.5). But my guestimate is the Qt upgrade that we were obligated to do in order to comply with the openssl security requirements. If it's a highly used feature, I can push for the priority to increase, but if the source of the issue is in the Qt, then it would be super messy.
Well messy sucks as it often leads to what we already have here and that is an "Unexpected Consequence".
Updating all the models is important to professional designers/technicians. They lay out their build plate with multiple copies of a model, look at the slice, and realize that if they make a minor tweak to the model the slice will result in a better print, less supports required, better orientation ... whatever. So they reload the model and only the initial model updates. Unfortunately, they have added Support Blockers to all the models and also unfortunately, those blockers are linked to the individual models which now need to be deleted. They have to re-do the entire build plate (except for the original) for what was a minor change to the model. That's a serious hit time-wise, and time is money. A real downside is that if it is a very minor change to the model, and it is internal, that some users may not know that the copies did not update. That's a bad situation.
Whether it's messy or not, I would advise to bump this up. I know a lot of development is driven by the kids printing mini's and dnd characters. The high-end users need some love sometimes too. They are the ones most likely to be UM customers, or future UM customers.
