AutoCAD Civil 3D :: Survey Points With Ground Coordinates Are Scaled Inserted Into Drawing?
Sep 5, 2013
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 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.

I've not used AutoCad for probably 15 years. I used it in my government job, but have forgotten many commands. I have inserted a building survey into a new DWG, and remember that I can find a dimension on that survey, and use it to begin a scale for the drawing, so that I may make additions to the building drawing.

My problem is that I require to extract coordinates from specific points on the drawing and set them out on the ground at the real location.
On the drawing there are several base station locations with known coordinates. I have tried coordinating the drawing using Ctrl a, move, then type in the known coordinates of one of the base station location but nothing happens. I have also set the drawing to world with no change.
The coordinates in the bottom left corner are shown but are around 500m out.

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 have a point file specifically a PNEZD file. when i import points into the survey database the coordinate in the database is correct but the coordinate on the drawing tends to be 5 feet off one way and 1 foot off the other. When I import point through the points pull-down menu the coordinates are correctly shown. When I import point into survey database from drawing the coordinate is incorrect in the database but correct on screen.

What I have is northing/easting survey data starting at an arbitrary point. The rest of the points are measured from that.
I do know the global coordinate of the base point, but no other points.
My question is how can I take all of the points and create gloabl coordinates out of them. I assume this is possible because I know the global coordiane of our reference point, I just have no clue how to do it in CAD.

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'm trying to make a standard block which will automatically read the co-ordinates! i have started making it trying to use fields, but when inserting the block into the drawing it stays at x=0, y=0, which is the point in the block. how do i get it to read the point in the drawing, and also how would i always get it to read the world ucs.
i have attached the block i've started, haven't added any dynamics yet as i'm just testing it.

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.

When I add an image to my sketch the main body then appears "of the ground" as you van see from the attached screen shot. The shadow and reflection is distant. The minute I remove the instead image the object and the shadow touch again as it should be.

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?

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.

I have been using the "LIST" command to get coordinates of a point. The list can be as long as my monitor is high. I need to copy the coordinates of about 3 000 points to a Microsoft Word file to manipulate with them.
The "LIST" command would show me about 4 points after which i have to press "ENTER" to get the next ones, but this is obviously pointless. How could i get the coordinates of very many points to a text file all at once?

I have the following 8 points of XYZ-coordinates:
Location SampleID X Y Z Depth Elevation FGACDC-SS01 FGACDC-SS01-S1 -77.055876 39.00845 314.5 0.5 315 FGACDC-SS01 FGACDC-SS01-S2 -77.055876 39.00845 297 18 315 FGACDC-SS02 FGACDC-SS02-S1 -77.055886 39.008643 319.5 0.5 320 FGACDC-SS02 FGACDC-SS02-S2 -77.055886 39.008643 302 18 320 FGACDC-SS03 FGACDC-SS03-S1 -77.056203 39.008736 311.5 0.5 312 FGACDC-SS03 FGACDC-SS03-S2 -77.056203 39.008736 294 18 312 FGACDC-SS04 FGACDC-SS04-S1 -77.056203 39.008491 304.5 0.5 305 FGACDC-SS04 FGACDC-SS04-S2 -77.056203 39.008491 287 18 305
These 8 points are for 4 sampling locations with 2 depths for each sampling location. I used AutoCAD 2012 a little bit before and I am new in using AutoCAD Civil 3D 2013. What are the key steps and tips of using the values of XYZ-coordinates listed the above-mentioned table to input manually into the AutoCAD Civil 3D 2013 program. Note: 4 sampling locations are in the 4 corners of a square lot and the 8 points should look like 8 corners of a box.
