Q - question

"Valid hatch boundary not found" when hatching on Xrefs.

A - answer Some external references (xrefs) cannot be used as hatch boundaries (borders) for hatching in the main drawing.

Normally, you can use xref entities (objects) as hatch boundaries for associative hatching using "inside" points. If you get "no valid boundary" messages trying to hatch with xref boundaries, your xref is probably too complicated or it is clipped. It is not possible to use clipped xrefs (XClip, XrefClip) os hatch boundaries. You can also try to simplify the boundaries by switching off excess layers, or you can RefEdit of the xref, or just NCOPY the relevant objects from xref to the main drawing.
