Do you transfer the whole file, both ways, or do you just transfer the ones you have revised?
I have found that if I go and shoot 1-100, in the DC, then return to office, and calc 101-125, that if I SEND 1-125 to the data collector, well, it REVISES some of the 1-100 (probably due to rounding) somehow. So, when you upload, do you use the whole file, or just part of it?
It is vexing that there is a difference, even if it is just 0.00000001, because it makes me wonder what happened in ACAD.
Thoughts?

Well, most of the time, I just make a new upload of the entire file, delete the other one, that way, I know I have the latest and greatest file with me in the field and not some abomination or molested version thereof.
However, with TGO, I typically just send the new points due to the PITA of projections and what not.

Way back when (1989 or so) TDS rounded coordinates to 4 decimal places in the data collector. Are they still doing that?
Acad works calculating data out to 16 decimal places. I don't know what the current TDS works at, but it could cause some small differences I guess. I would just remake the file and send it all as one back to the collector. When I was using Microstation to work on DOT jobs ans I imported a Acad file to Microstation it was o.k. but when I imported a Microstation file to Acad, Acad thought all the lines were not joined because Microstation only calculated to 8 decimal places. I assume the newer versions don't do this, and I use only this as an illustration as to what might be happening.
Even the HP48 would allow you to fix the number of digits after the decimal.
If you had more than 4, some coords would run off the screen. 4 is the bare minimum to assure the accuracy to the second of an angle, so for what I usually survey. My cogo program keeps tract to 27 digits after the decimal.
Personally, I just keep sending all points back and forth. I can't measure past 3 decimal places anyway.
Thanks for the replies.
I hope to get this completely eleminated. I know a Carlson DC uses the SAME file in both DC and Carlson Desktop.

we transfer to a TDS Ranger with Foresight DXM. We typically send the whole file and prefer not to work in batches in case something were to get overwritten or fubar'ed.
I do recall that when looking at the coordinates in the Job/edit points menu that coordinates appeared to be rounded. However when inspecting our coordinates by editing/viewing the individual point the display window showed the full 5 or 6 decimal places. This could be unique to our DC due to some setting stashed away somehwere. You might check it out and see if yours is doing the same thing.
Good luck.
