Moving merged balloons bug

BH_8416148 — Thu, 02 Oct 2025 13:09:06 GMT

Hi! I use merged balloon symbols for multiple component. If this merged balloon symbol is moved the leader always move to the middle and works inconsistently.:

Is there a config key settings to disable this behavior? I think it is a new thing, never happened in previous version of creo (creo8).
I'm using: Creo parametric ver. 10.0.4.0

Thanks in advance!

Looks like the balloons are trying to flip sides when moving from one side to the other. I have never seen them flip when moved. In 7.0 and Creo+ (12.0) the balloons I use move without flipping and need to be rearranged by dragging when move from one side to the other. In your example, you would need to drag 66 & 83 to the other side.

I do get some jitters from the balloons in Creo+ related to the snapping positions. The snapping can be turned off in the ribbon (Table > Balloons > Snap To Guides).

You appear to be using a custom BOM balloon. Can you provide a simple example of a drawing with BOM balloons?

Thanks for your answer! You're right it is a special balloon symbol. With the basic balloon symbol, there isn't any problem when moving.
Unfortunately i didn't find the solution on symbol edit. Symbol is attached.

I wasn't able to get exactly what you are showing with your balloons. I did get something similar randomly a couple of times. Each time I could correct it by dragging the merged balloons to the opposite side of the base balloon. I was also able to create the issue by clicking on the right spot to get a double arrow as shown in the below video. I will give it a try in Creo+ later.

Tried it out in Creo+ (12.0) and had the same issue as you are experiencing. Relocating the BOM balloons one-by-one from the end works to fix the order/attachment location.

I would call it a bug in the program and suggest you open a support case referencing this thread. https://www.ptc.com/support/case-logger

Thanks for your help! Unfortunately I'm not able to open a support case. I would be very grateful if you could help me with this.

I opened a case with PTC, since we will soon transition to 10.0 of higher soon, and support was able to recreate the issue. It is being worked on, and I will be updated with any progress.
