# 1. This example shows how to load ACIS based entities by the xref module from
#    one DXF document into another DXF document.
#
# 2. How to transform ACIS based entities.
#    The current implementation of the transformation is a trick.
#    The ACIS data format is not documented, therefore ezdxf puts ACIS based entities
#    into an anonymous block and transforms that block.  This transformation is applied
#    when exporting the DXF document.
