Barry,
Please let me first note that I have read your posts and will continue to do my
best to stay more current on the issues involved here on the Autosketch
discussion group.

I have two questions for AutoDesk.
1. If this is a known issue why is not this option selected by default, in
fact why is it there at all?
AS only has 3D pretensions so I presume can't handle dwg 3D items anyway.
It is important to note that not all drawings or drafters are alike. Certainly
having some flexibility about how to import DWG files can be important. When
importing a dwg file being able to map SHX text to True Type font makes the text
come into Autosketch as text and not as a group of entities.
I found the following information in the Autosketch help files
Index : Importing Drawing files
Topics Found: Autocad Conversions.
I hope this helps!
AutoCAD Conversions
AutoSketch imports and exports AutoCAD DXF and DWG files. The DXF filter reads
all versions through AutoCAD 2000 and AutoCAD LT 2000. When saving a file, three
DXF filters and two DWG filters are provided so you can create either Release
12/LT 2 or 2000 files. Entities are converted as follows:
Entity conversions
From AutoSketch Into AutoCAD
arc arc
circle circle
ellipse ellipse
line line
marker block or point (No-plot diamond is
ignored)
symbol block
text text
irregular polygon polyline
polyline polyline
sketch polyline polyline
fitted curve polyline
spline curve polyline
OLE Object cannot be exported
pictures cannot be exported
The following conversions occur when exporting to DXF or DWG:
Pixel width is ignored.
Layer and block names are modified to conform to AutoCAD naming conventions.
Only alphanumeric characters, "$", "_", and "-" are allowed. Invalid characters
are converted to underscores.
Text borders are lost.
Only database fields associated with symbols are exported as AutoCAD
attributes.
UIDs and hyperlinks are lost.
Polygons with holes are exported as multiple polygons.
The following limitations should be observed when creating files in AutoSketch
if you plan to export them to AutoCADespecially if you plan to re-open the file
in AutoSketch.
Limit names to alphanumeric characters without blanks for layers, fields,
symbols, and so on.
Do not use pixel width for entities.
Do not use fields assigned to entity types other than symbols.
Dimensions are exported as the subentities that make up the dimension.
AutoCAD R12 Specifics:
Bitmap fills are not exported.
The following limitations occur when exporting from AutoSketch to AutoCAD
Release 12.
All TrueType fonts are exported as standard text styles. For best results, use
the following AutoSketch fonts:
AutoCAD Font AutoSketch Font
TXT TXT.ttf
COMPLEX Complex.ttf
ITALIC Italic.ttf
SIMPLEX Simplex.ttf
The following conversions occur when importing DWG into AutoSketch:
Entity conversions
From AutoCAD Into AutoSketch
3D face irregular polygon
arc arc
circle circle
dimension dimension (Range and +/- tolerancing only)
ellipse ellipse
group group
hatch group
block symbol (see Symbol Note)
leader polyline/curve and optional marker
line line
Minsert grouped, multiple symbols
Mline grouped lines (endcaps and fills are
lost)
Mtext text (see Text Note)
point point marker
polyline (2D) and lwpoline polyline, spline curve, or fitted curve
polyline (3D) polyline or fitted curve
ray Line (drawn 10 units in one
direction from the basepoint)
solid filled irregular polygon
spline spline curve
text text (see Text Note)
trace segment filled irregular polygon
x-line Line (drawn 10 units in either
direction from the basepoint)
Notes
Paper space is ignored when importing AutoCAD drawings which utilize model
space. If no entities exist in model space, AutoSketch will translate all
entities from paper space.
AutoSketch automatically performs an autofit operation when importing AutoCAD
files. This may result in a repositioning of the drawing origin.
Layer information within a block is lost on import into AutoSketch. Entities
within an AutoSketch symbol are placed on the same layer as the symbol instance.
It is suggested that you explode blocks before import to maintain best visual
integrity.
ATTDEFs are converted to fields with the field name from the Tag applied. A
formula is inserted at the location of the ATTDEF in the form of
<%db("TAGNAME")> if the ATTDEF is visible. When an instance of a block which
contains an ATTDEF is placed, the attribute is forced to the default position.
Custom position of attributes within an instance is not supported.
Only line styles that are already defined in AutoSketch can be imported. All
standard AutoCAD line styles are included in AutoSketch Release 7, however
custom line styles must be added manually. Complex lines styles are ignored and
mapped to solid. For information on creating custom styles in AutoSketch see
Creating Custom Pen Styles.
Hatches are imported as polygons with hidden edges and a fill pattern that
corresponds to the hatch pattern. If AutoSketch does not have a hatch pattern
that matches the AutoCAD pattern, the hatch is broken into groups of individual
lines and/or point markers. AutoSketch has no by-layer fills, so when importing
an entity from AutoCAD that contains a solid hatch with by-layer fill, it
assigns the entity's layer pen color to the fill. By-block fills are not
supported and become black. Associative hatches loose their associations.
SHX text is imported as polygons and polylines when importing AutoCAD drawings.
Note that the Map to TrueType check box in the DWG Import options dialog must be
selected. If Mtext contains a mix of TrueType and SHX text, the SHX text is not
converted to polygons and is instead converted to a TrueType match.
When you import DXF or DWG files, AutoSketch ignores most objects it does not
recognize (that is, objects that have no equivalent in AutoSketch). However, in
the case of 3-dimensional objects, AutoSketch also gives you the option to
"flatten" 3D objects. When a 3D object is flattened, it is first translated into
facets, which, in turn, are translated into 2-dimensional polygons.
AutoCAD entity AutoSketch Import Options
3D Solid flattened or ignored
Body flattened or ignored
Feature control frames ignored
OLEframes ignored
Region flattened or ignored
PolyFaceMesh flattened or ignored
PolygonMesh flattened or ignored
Proxy ignored
Viewport ignored
Shape ignored
Raster image ignored
Similarly, custom application objects, elevation, extrusion direction,
thickness, XDATA, and XRECORDS are ignored on import.
The Import Options dialog box, which is only available when importing a DWG or
DXF file, allows you some control of the way AutoSketch imports AutoCAD
drawings. The Import Options dialog box allows you to assign a default
measurement system to the existing units in an AutoCAD drawing. For instance,
you can assign a value of 1 inch to each unit in an AutoCAD drawing. The Import
Options dialog box also allows you to control whether some 3D entities imported
from AutoCAD are flattened or ignored (see table above).

2. If there is an article on the knowledgebase why on earth didn't someone
from AutoDesk say so when I first posted the problem? It would have saved me
a whole load of grief!
