I would like to adjust a range of points by x,y,z. (autonomous(here) point and OPUS point) Do I have to manually pick them on the screen and then pick the "from" node and "to" node or is there a simpler way? Can this not be done using the point numbers?
I know if you make a point ground you can change all the elevations in the point group at the same time. As far as moving them, you can just use the regular AutoCAD move command to perform that.
If you have a lot of points in the drawing but you want to only move some of them you can put all the points from a point group on the same layer. That way you could have just points you want to move show up on the screen and you don't have to sort through them to find the ones you want to move.
Hope this helps and make sense.
It depends on how you brought them into C3D. If you used the Database (typical if you do line work) the move command won't move the network. If you simply imported points the move command is easiest.
I would seriously consider updating the point and re-processing in whatever package you use. The advantage being you can mean redundant shots and quantify your precision.

I don't think that there is any slick way to do this in C3d other than MOVE. Kind of makes you go "Huh", doesn't it?
I prefer to do this sort of thing in a manner that leaves some sort of metadata (ie/ a paper trail) in any case. My preferred method is to load the measured vectors into StarNet and substitute in the OPUS position for the FUGARWE base position. If you don't have StarNet (or SurvNet, in Carlson Survey) or some other way to re-reduce your raw data to coordinates you could still perform this translation in an Excel spreadsheet. And if you don't have Excel, Open Office Calc is a good free alternative.
I would change them at their source and reimport them rather than try to move them in civil3d. The survey database doesn't work like it used to. Personally I haven't moved a point within CAD in years, I always go back to the source then reimport the correct coords.
If you must move them in C3d you must be certain they have not been imported through the survey database. To be able to move the points around in your .dwg they have to be imported through the drawing import points menu function. Once that is accomplished you can move, scale, rotate them as you please using a variety of normal cad functions. I would suggest making a point group out of them and then to ensure you don't leave any behind before you move them.
If they are COGO points then the move command works.
If they are SURVEY points then you must rotate and translate in the Survey database.
Could you not just update the LLH coordinate in your data collector and have it spit out shiny new coords? The observations are not changing merely the base point.
Glad I use Carlson Survey within C3D. Working with points is much easier. Don't miss the plain Jane C3D
Sir V,
The Transformation Tab can pull off pretty much any Transformation, even automatically calc'ing the Scale Factor from your chosen points. You can also do transformations in the Survey Database.
The only thing you'll need to adjust is your elevations:

Neat. But I believe that a transformation is quite a different thing from a translation.
how about the align comand?
