NCopyExtra
Sort / Purpose: Copy nested objects from xrefs or blocks into the current drawing so they become local entities on local layers that mirror the xref layer properties.
• Scope: Works on objects selected with NENTSEL / NENTSELp, including items on xref layers like “_XREF|VG_KK”.
• Goal: Quickly “detach” geometry from xrefs by copying it out onto new local layers that inherit color, linetype, and lineweight from the original xref layer.
