How to create blow up details in detail sheets?

Hi, I am trying to create blow up details in ORD V10. I tried to do these details in the sheet model which worked fine until printing - it causes it to crash and create massive PDF's so I'm wondering if there is a good way to do this with named boundaries, and if not what is the best way to do this in just the default 2D model?

update - making the details in the sheet model (by referencing in my design file) rather than the default 2D has seemed to work well and not cause the file to crash.
