I have tested it.
In the iso view, it was not sorted as I wanted.
Considering the reason, the spacing is reduced in the view as it is.
The position expressed is intact.
The "split" function is thought of as a function that should be used in a flat view.
the only way I have found for such "breaks" is to have twice the same view (ISO), reducing the border (similar to split curve) and then move the view accroding to the wanted result.
This more or less is no to much different or complex then breaking the view
Default breaking seems to be work and to be created for main views only
It would be a nice enhancement to be able to break iso views and maintain alignment of the components in the view.
