Hi Robert and everyone following this thread,
Thank you for your patience, and especially for taking the time to share the additional testing, screenshots, and recording. We’ve reviewed the behavior you described regarding Smart Guides and snapping between objects contained within the same group.
To clarify, the current behavior is that Smart Guides do not support snapping an individual object to other objects within the same group in the way described here. This is existing InDesign behavior rather than something caused by your Smart Guides or document grid settings.
We understand how supporting this workflow could make positioning and resizing objects, particularly image content within grouped frames, more efficient. The request for this capability has been noted as a feature enhancement.
For now, a workaround is to temporarily ungroup the objects when you need Smart Guide snapping between them, make the required adjustments, and then group them again. Depending on the layout, Align/Distribute controls or guides may also help with precise positioning.
At this time, we don’t have a timeline to share for a change to this behavior. We appreciate everyone who has shared their use cases and feedback on why this functionality would be useful.
Thanks again for your patience and feedback.
Abhishek
