STEP presentation styles colour what they style: a solid in the standard
index colour its RGB is close to, else in the true colour, and a face
with a style of its own (with the edges round it) through the face and
edge colour attributes. IGES trimmed (144) and bounded (143) surfaces
come in as one SURFACE each in the entry's colour, after the solids,
which now come in last first. Faces show a true colour attribute in
that colour.

ACIS text files come in one object per body (3DSOLID, REGION or SURFACE).
STEP B-rep models become a block per product with component inserts at
their placements, scaled to the drawing's units; IGES manifold solids come
in as 3DSOLIDs scaled to the drawing's units with their colours. Splines
that are exactly analytic shapes are kept as those shapes. Windows
metafiles become a WMF<n> block of polylines and text fitted to half the
view, placed at its top-left corner or by WMFIN's insertion prompts. The
Import File window lists the four formats as supported.
