Xref tool is not so used in a normal Allplan BIM workflow (at least as far as my experience is concerned), but it might be very useful with multi-story buildings!In that way you have the possibility to change the reference story and the changes will be applied on the XRef models, without any problems of QTO (’cause the elements are recognized through the Allplan’s reports).
You can go deeper on Xref tool using the online guide of Allplan here.I link you the brief Youtube video about this interesting use of XRef hereYou can find and download also the original video attached at the end of the page.I hope you’ll enjoy it :).
