DXF, last time I looked, was an ascii format which should make it easier to
glean information from. How easy would depend on exactly what format the
geometry data is held within the file. I'd be happy to take a quick look at
the file if you've FTP or similar where you can drop it.

Subject: converting mapping DXF file
Hi All,
Just picking brains here. We need to get some mapping data into XSI
purchased from Ordnance Survey. The files are essentially height data
in
DXF format though there are two other formats, NTF and ArcGrid. Now
we've been trying to convert the DXF sample file using various
converters, but the file is huge, over 180mb of data and nothing really
wants to convert it. What we need is to somehow open the file, reduce
it's size (resolution), and output a poly grid or grid of nulls, to get
into XSI.
Has anyone had experience of this? What I'm wondering is, would it be
possible to get a piece of code that runs through the DXF file and
reduces its size. ie extracts every 3rd point or something. Basically
the files only come in one size, which is our main problem, and we
don't
necessarily need the resolution they're supplying.
Any help would be very appreciated! Thanks
Chris
