I routinely have to load points from an acad dwg into Terramodel to
prepare files for automatic grading and layout using - usually - gps,
but I have done data prep for total stations as well.
Just about all survey sw works with ascii point files as well as any
native format of file from the mfg., so I'd bet that yours does also.
Almost every time I've prepared data from an acad dwg I've had to
follow a slightly different procedure.
The last time I used the "attribute extraction" tool in acad to bnuild
the required files - it seems to be the most flexible and complete way
to do this. It also exposes the bad procedures followed by the
draftsman better than any other way, such as "existing" points drawn
on the "proposed" layers, etc etc etc etc etc.
Have a look at this in acad, then select the layers you want the point
data extracted from, then make up your file as containing the
following in this order:
point number,northing, easting, elevation,description
have the attrib extractor number the points sequentially for you, and
don't worry too much if you end up with some duplicates - most sw
reading these files later will just renumber them in sequence anyway.
It will be important to spend a little time getting the descriptions
right - a lot of time can be wasted later trying to tell what point is
what - the descriptions will help a lot with this.
Also, many of the programs reading the ascii point files will not work
right if you do not have an extra blank line at the end to indicate
end of file.
Whenever any program asks for file format, or file type, use ".TXT" if
you can - then you can edit the output with NOTEPAD if you have to
alter anything before inputting it to the total station.
Alternatively, you could call it a ".CSV" file, and edit it with XL
(comma separated value file).
Post again if you can't get to first base with this stuff.
