This will be another quick tip, for those new to the Civil 3D platform and using TDS.
We used to have problems with data being overwritten. My crews dump their data daily and overwrite my calcs, and when I get them a tidied up file, I overwrite their subtle changes like an adjusted elevation. So we now merge their new calcs in.
I use the export point group (previous topic post), and send out only what was calc’d in today’s session.
*TIP* Not only is this needed to merge a smaller collection of data, but it is great when I am out of town (like AU). If anything goes wrong, each merge is dated so whatever was corrupted can be reintroduced a-la-carte.
Locate the Survey Data Collection Link found in the Create Ground Data Panel pulldown on the Ribbon’s Home Tab. This will start the Survey Link. Merge can be found in the Conversions menu.
Add the file names that need to be merged together. I simply add the merge data to the main file. When completed hit merge. Conflict resolution can be managed through the radio buttons. If you leave it on prompt (like I do) a dialog will appear if there are any conflicts.
Simply pay attention to the options. The dialog does seem a bit overwhelming, especially in a hurry. Discard data in file 1, or file 2, etc.. Just look at the option, and identify which file is file 1 or 2.
I teach people to talk themselves through it if needed. “Do I want to renumber…Probably NOT!!. File 1 is my good data. File 2 BAD. Do I want to discard anything from File 1? NO. So Discard (overwrite) data in File 2. YES”.
Discard should have been reworded to “Overwrite” since that is how most of us have been conditioned.
That’s it. Once completed, a dialog appears stating how the merge went. This process seems to make some folks quite uneasy, but once you blast through it a few times it’s very simple. It just needs a touch of usability.
