Can I detail a part in 1 drawing sheet and refer to its origin on another sheet with the split bubble ballon ?
Though I am not sure what " split bubble ballon" you are refering, however yes you can copy/paste drawing views from one sheet to another.
I wasn't very clear in my question, let me try again.
Can I annotate the detail view with item numbers (balloons), on a drawing sheet (say sheet 2) of a part placed on sheet 1, and refer back to the part, giving the sheet number (1) in the bottom half of a circular split line balloon and the item number at the top ?
This is possible.
You will need to assign a custom property to the part where it says sheet 1.
