AutoCAD Civil 3D :: Update Survey Points In Drawing
Jun 27, 2012
Here is my procedure.
1. Import survey point via ascii file into a new drawing call it Field-dwg.
2, Create a survey data base
3. Import all points in the the data base under import event.
4. open existing drawing, work-dwg, import points as needed from the Survey Data Base.
Problem : Survey points needs be renumber.
I goto field-dwg, and fix the points (renumber).
open survey data base for edit, and import Event, field-dwg/points/update : nothing happen
also try Import Event, field-dwg, survey points, update : nothing happen
so I re-import the points, all is good.
Then I goto work-dwg, and try to update the point, nothing happen.

Using Civil 3D 2013Coordinates coming out of survey equipment are modified state plane GROUND (scaled up from the origin by the combined factor).Drawing is setup with state plane coordinate system with user defined transformation to establish geodetic reference and the ability to label lat/long or import Bing map data.Survey database is setup with "No Datum, No Projection" (data is already at ground, I don't want ot transformed).Import style is PNEZD and is set to use Northing/Easting not Grid Northing/Grid Easting.After importing points into survey database, coordinates of survey points match the CSV. This is good.After importing points from database to drawing, they are taken as grid coordinates, are scaled again and are off ~5,300 feet northeast.Why would Civil 3D assume the points in the database are grid and scale them when the import style used did not specify grid? Is there a setting or something I can do to tell Civil 3D to leave my coordinates alone?

here's my process:
1- Import the asc file into my drawing.
2- Convert the asc file to a FBK file
3- Import my FBK file. The survey figure linework generated doesn't overlay my previously imported asc file. I checked the FBK file and the coord's match the asc file. I'm confused as to why the survey figures don't overlay the survey points from the asc file, since the coords match in both? The survey figures are all shifted .7' and 54deg. from the points. The elevations are all good on the survey figures, as they match the survey points.
So my quick fix is to explode the survey figures, since I don't really need them for what I'm doing, and then select all the 3d polylines and move them to them to an appropriate survey point. Everything then looks fine and I can get the job done.
However, I would like some insight as to why this might be happening. It's strange that the FBK and asc coordinates match, but the survey figures aren't lying over them.

I am tired of re-creating Description Keys everytime I want to bring in Survey Points into a drawing. I have tried to drag and drop, but that does not seem to work for me. I can's copy it. Is there a way to get Civil 3D 2010 Description Keys into Civil 3D 2012.

I had an issue where I dropped points into my drawing for a survey and they weren't at the distance compared to recorded plat. I have checked the points mathematically, and they were dead on. A coworker suggested that I WBLOCK the points I was working with that way I don't move single points out of place. I disagreed, because the way i move points is I use the TOOLSPACE and move them as a group. So what I did was to drop the points again and now they were dead on the second time. I don't like turning points into a block due to the fact that it messes up my drawing.

My field crew assumed a coordinate system and surveyed a job. I need to rotate the points in my dwg to match another survey. I have not found a rotate points command. Other LDT type commands have been replaced by standard ACAD commands by adding the transparent commands to them. I tried to use the ACAD rotate command and the transparent commands to rotate my points, but there is no transparent command to find multiple points. I need to select the points by point number range if possible.

I was wondering what is the difference between importing points under the Prospector tab versus importing points under the Suvey tab? And how either of the two methods relate to using Data Shortcut?
I would like to create a survey topo drawing that contains points and surface information which other Design drawings that are attached to the Data Shortcut project can access but not be able to make any changes to the original points and existing surface information.

what if i have points that are non-consecutive? the survey crew is new at this so i'm getting some higher number points that line work wise appear in the middle of lower number points. the figure seems to draw numerically. is there a way to do a figure by proximity?

I have imported surveydata into the survey database from FBK and processed linework. I do as many edits to my figures as I can by editing point codes and processing linework, then I fix the rest of the figures manually editing them and pushing the changes back to the survey database.
Once you have started manually editing figures you can no longer 'process linework' as you get double ups of figures you manually edited.
My issue is that I have made some adjustments to some of my control point coordinates after manually editing figures, so that all my survey points move. I try to update the survey figures so that they move with my points but Civil3D tells me that it cant update them because they were made by processing linework.
Is there anyway I can get my figures to match my points without reprocessing linework and then making all the manual edits again or exporting an FBK from the database, remove the figures and points from the dwg, reset the network and import the new FBK?
We should be able to update figures without processing linework, even if that was how the figures were originally made!

Every week I recieve new survey data (typically around 20 points) to insert onto an existing surface of our local landfill.
The surface is displayed as minor and major contours. The new survey data typically always has higher elevations then the exist surface and shot roughly 2 meters apart.
Here's my issue...when the survey data is inserted and the surface is rebuilt, the contours seem to turn into little cones at each new point. see attached...
how to eliminate these 'cones' so the surface contours seem more relistic?

Sometimes when i import points Civil 3d creates a Point group in the drawing with the name of the point file, sometime it does not. I prefer when it does create this point group. It always seems to create a Survey Point Group. How do i control wether or not a point group is created in the import?

How to set stakeout points on a pipe network? I have an alignment from the engineer that also has a pipe network associated with it that I would like to automatically set points vertically and horizontally on (like I can do with a regular alignment/profile).

While adding a vertex to a survey figure, if I click too near (like within 0.5') a survey point, the new vertex snaps to the survey point and uses its point number as the new vertex. Is there a setting for this snap feature to turn it off or change the tolerance?

I am new to Civil 3D upgrading from LDD2009. I am trying to edit some point descriptions brought in through a fieldbook import through my survey database. Under my survey database in Survey Points I hit EDIT POINTS and it brings up the SURVEY POINTS EDITOR. My points are listed as white observed points but when I click on the description cell it won't allow me to change anything.

I remember in LDD you could insert points in an area, Is that possible in civil 3d. I have a small area of an big project that i want to review all the points. This project has 517000 points in it so it takes to long to insert all of the points.

My surveyor gave me a topo survey done in no particular coordinate system. He set up his total station on a PK nail and gave it a coordiante of (5000, 5000, 100). I used this survey to generate a surface.
I also have a site survey of the same site, done in state plane coordinate system. the two surveys have mulitple common points; pk nails, iron pins ect.
What i need to do is move the points for the topo survey over to the survey that is in state plane. A simple move command will not do this.
How do i go about moving these points to thier correct location without having to manually edit the .txt file?

In 2012, the survey cogo points no longer seem to update after browsing to the observation data, making an edit and then saving. It worked fine in 2010.

I’ve run into an issue with importing survey data using field books.
I started by importing my primary control using a field book. There were no issues with importing these points. I then proceeded to import subsequent field books with additional control and then topographic mapping. In the last field book some points were accidentally overwritten due to an error in the field collection. No error message was given to let me know the survey points were in use and being overwritten. Luckily I caught the error before I proceeded to the next field book.
I tried to reimport the field book that originally created the points that were overwritten. At that point C3D told me that the points being occupied in the field book did not exist. I checked the point list for the primary control field book under the "Import Events" in the Survey Tab of the Toolspace and indeed the points in question were no longer listed.
I then proceeded to reimport all the field books in order, starting with the primary control. I got through several of field books before C3D again told me the point being occupied did not exist. This despite the fact that this same point was occupied in previous field books. After trying once again I was able to get through the field books.

Running C3d 2012 here, but haven't used prior versions. I'm using fieldbooks to import survey data. If there is an error of some kind and I "Re-import event" for the fieldbook, then the occupied points from the field book are deleted out of the survey database and I get the resulting error of "point invalid" during the import. My fix is to go into my control drawing and import the control points from the drawing into the survey database then run the "re-import" again.

When I import points from a survey database there is a very large new number being assigned to points that have overlap/numbering conflicts.
I had some survey from one source that was in the 1000 pt # range & additional survey that was in same numbering sequence.
When importing the points I chose "Resolve all" it is renumbering the Point number value to the 5xxxxxxxx range?
Is there some setting where I can change this to a lower # or how/why this is happening?
Next Point Number value @ Settings Tab>Point>Commands>CreatePoints>Point Identity>Next Point Number = 3.
I've attached a couple of captions illustrating the issue.

I'm exploring the option of going from normal autocad and PDS (for our road designs) to fully using Civil 3D 2013.
Generally we only recieve a survey drawing as a 2d cad file with height points represented as 2d text.
In PDS all we need do is 'convert text to point' and create a ground model, this gives us a 3d ground mesh to work with.
In Civil 3d i've found 'movetexttoelevation' but now i'm stuck with adding a point at the node of the text object, and then I need to creat a surface model to overlay a 2d siteplan andstart creating our roads.

I've been sent a survey drawing with elevations. The format is a block, but it's not a named block. Each entity has it's own block name. So, I'm having trouble getting at the elevations. I can't seem to export and get the elevation or Postion Z.
I've tried exploding these blocks, but all I get is a couple of polylines, and some text. Useless. I've attached a sample drawing with a couple of these points.

I imported survey data from a file into the drawing and created a surface from the points and figures. No problem. Engineer wanted to change the datum from assumed to known. At this point all figures have been copied to a new layer flattened and changed to 2D polylines in order to hatch. Then the figures reimported. I raised all the points with the edit datum and raised the figures with edit survey figures. Surface was adjusted and tweaked. Everything was fine. I open the drawing and all the figures are back at assumed datum and the points are on the right datum. Now when I tweak the surface it uses the bogus elevations from the figures. How can I get my figures to save the adjusted elevations?

I have an AutoCAD file which includes 3d points and lines which represent an existing ground survey. The scheme is approx. 8km and points are spaced in a dense grid. The survey was undertaken using aerial (Lidar) methods, before being rationalised using aerial imagary to identify linear features such as kerbs, fencelines, etc, which are included as 3d polylines. Items have been grouped by the surveyors and adopt individual cad layers and linestyles, etc.
Basically, I want to incorporate all of the points and all 3d polylines into my Civil 3d Survey database in order develop a roads design.

I'm looking to change an elevation of a survey point within a drawing. I can see where it is possible to manually unlock the points from the Survey Database to allow the user to edit the point. I'm not seeing a method or property in the API Help for 2013 to do the unlocking with code.
Also is it possible to convert a Survey Point to a regular Cogo Point through the code? Or do I have to delte the point and then recreate it as a COGO point? I think this will be my work around if the above doesn't work.
