Clipping external references
When you attach a drawing as an external reference, all of the referenced drawing
displays in the current drawing. However, after you attach an external reference,
you can define a clipping boundary that determines which portion of the referenced
drawing is visible or hidden.
You can edit, move, or copy clipped external references the same way you modify
unclipped external references. The boundary moves with the reference. If an
external reference contains nested clipped external references, they also appear
clipped in the drawing.
TIP In addition to clipping external references, you can
also partially hide blocks using clipping boundaries.
