Importing GPS coordinates into 2005 LT

Hello,
I have been asked to post a thread by someone who is attempting to import GPS coordinates into AutoCAD 2005 LT. The program he is using came with his Garmin GPS 90 unit and allows one to save the points into a DXF file which can be opened by AutoCAD. But, once converted, the points become cartesian coordinates. His concerns are:
1. Is this the best method for importing these coordinates?
2. Is this something that would be better done in full blown AutoCAD as opposed to LT?
3. Once converted to a DXF file, are the points still to scale?
4. Should we be using some sort of "middle man" software for this?

Any help that anyone can give will help out a great deal.

Thanks!

How are the points in the GPS stored? Are then northing and easting or
longitude and latitude?

AutoCAD Civil 3D can handle longitude and latitude. I don't think plain
AutoCAD or LT are set up to do that. Civil 3D is an expensive program, but
worth it if you do civil engineering all the time. If you stick with LT, it
is probably best to work with the X - Y coordinates unless you have a
specific need for longitude and latitude. I would think long and hard
before jumping from LT to full for civil work. If you are in the US, I
think you can cross grade right now from LT to Civil 3D for about $2000 US
plus the subscription cost of another $1000 or so. Bare in mind that the
Civil 3D will require training and short term lost production on the order
of the cost of the software or more, but in the long run you will be way
ahead after getting past the learning curve.

I can't say about the scale question without knowing the software used to
dump the GPS, but I would assume they are to scale. A quick trial should
give you an answer. Measure off 100 feet in the parking lot, take two
points and import them to LT. If you get 1200, your GPS is outputting
inches, 33.33 = yards, 30.5 = meters, and of course, 100 = feet. If you get
anything else, call the Garmin tech support.
