XCLIP clips block and xref references to a rectangular, polygonal or
closed-polyline boundary (Invert clip, ON/OFF, Delete, generate Polyline;
Clipdepth is ignored in 2D). The boundary is Insert::clip, in block
coordinates, so it follows its reference; other references stay whole.
Clipped references are drawn, plotted and framed (XCLIPFRAME 0/1/2) cut
to the boundary, attributes included, and their extents are cut to it.
DXF and DWG read and write it as the reference's ACAD_FILTER/SPATIAL
SPATIAL_FILTER; filters the model can't hold stay foreign data. Gap F2.

At the block name prompt, *NAME inserts the block's objects: after the
insertion point INSERT asks one scale factor and the rotation, and no
attribute values. A path (C:\parts\bolt.dxf), NAME=path or NAME= reads
the drawing through the io hooks and defines a block named after the
file (or NAME) from its model space, with the file's $INSBASE as the
base point, adding the layers, linetypes, styles and blocks it needs and
keeping this drawing's definitions. A plain path whose block already
exists asks whether to redefine it; NAME=path redefines without asking.
A file that can't be read is reported at the name prompt. The JSON form
takes `file` (optional `name`) and "*NAME".
