I tried the RAW->3DS and it worked fine. It was MUCH faster loading
into 3DS. I'm not the least concerned with the file size, only
mentioning it to get sympathy from anyone who has loaded DXF's
before. <g> The same file written as a RAW was processed in a
fraction of the time it took to load the DXF into 3DS. Thank you for
the hint!
