AutoCAD Civil 3D :: Creating EG From Survey?
Mar 15, 2013
I was curious what the basic workflow is for creating an EG from a survey. The catch is that we don't have a point file or elevated points on the drawing. The drawing is just that a drawing with spot elevations and linework. The lot is 100' long and 30' wide. An existing house takes up most of the lot with a street on the front and back. The idea is to try making a grading plan after I figure this first part out. Where would I begin with something like this to figure out the next step of grading a small lot?

It started happening whenever I try to "create a new local surveydata base" in Civil 3d. After clicking OK the folder for the database gets created, but does not show up in the toolspace window. It does show up in windows explorer in the place which I had specified on the pc. I have just installed Civil3d 2014 on my pc and I still have Civil 3d 2012 on it as well. I get the same problem from each version.

I am fairly new to the Civil side of AutoCAD, as I used to work primarily in Map. I am working on a street rehab project in which I need to take survey points showing existing elevations (centerline, flowline, and top of curb) and show existing profiles in a profile view. I have no problems setting up the profile view(s) or the centerline alignment, but I am having problems with creating the profiles themselves, and I have a two part question about them
Question 1: According to the user's guide, the correct way to set up an "existing" profile is by extracting it from a surface, but I don't have a surface to use. In reading through the various profile types, the best way to set up what I want seems to be by using the profile layout tools, but the help says that a profile layout is supposed to be for a final "proposed" profile, not the existing. Does this actually matter? Will I be breaking Civil functionality by creating an existing profile using the profile layout tools?
Question 2: In reading through the profile layout tools, everything seems to be centered around PVI's. Even using the "tangent tangent" method to add in points seems to only use the first and last point as controls, with everything in between treated as a PVI. If you look at the documentation here, points one and four are treated as actual elevations, while curvature occurs at points 2 and 3. In my case, since what I have is a series of actual points on a surface, each point should be an actual surface elevation with curvature occurring between points and not at them. What method should I be using to input the points in the profile?

trying to create contours from an exiting survey file. I am new to Civil 3d 2012. What I need to accomplish is create a 3d topo from the points with contours and then create a 3d model of the area.

I copied some Survey Data of AutoCAD Civil 3D 2013 for Surveyors to my C3D 2013 machine few weeks ago. Now I cannot do the "Import point file" of the Survey2 Data B in Survey Databases, because the Survey2 Data B is locked up - see the attached file that has a red circle with an arrow on. How I can unlocked the locked Survey 2 Data in the Survey Databases.

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 a land surveyor using AutoCAD 2012. Just new to 2012 version, previously used 2005 version.
My question is:
Is it possible to (and how do I) create a 3D model of a ground surface from field survey data which has been collected. The data i have is currently in Leica GSI format, and has x, y and z coordinates. I can easily transfer this into a .csv file i necessary.

We process survey data using Attributes to add extra intelligence and reduce errors.
For example, when shooting trees, the RAW file will contain something like this:
SS,OP 50,FP1299,AR308.2057,ZE91.0918,SD128.282,--TREE
FC,PN1299,FNTREE
AT,TNSZ,TV11.0
AT,TNTY,TVMAPLE
or when shooting a street sign:
SS,OP 50,FP1437,AR324.1135,ZE91.4728,SD123.235,--SIGN
FC,PN1437,FNSIGN
AT,TNTY,TVNO PARKING
The FC code sets up that attribute information will follow for the point number indicated by PN and the FN is basically explaining the name of the feature type. On the collector, this is all menu driven, making for few data entry errors.
The AT codes list the attributes name TN and then the TV reports its value.
Is there a way to preserve these attributes and their data when processing them into an FBK? Ideally, they would need to become part of a point description.
When processing this for that "other" CADD package, I am able to use these values in building labels for my survey points.

I was following Civil 3D 2008 Education Curriculum Module 04-Survey on how to import field books, create points and figures, insert them into the drawing, and then (per page 04-35), remove the network from the drawing.
Now I have a serious problem, and cannot add any new Networks. The "Name" and "Description" appears, but there is no place for a cursor entry.
Do I have to re-install the program?

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.

We need to move a survey point. I know the point can be unlocked in the drawing and moved, but how can the survey database be updated? After the point is moved the database does not update even after closing and reopening the dwg and database.

My company has upgraded to new computers recently (Windows 7, Civil 3d 2012). Some of the new computers are unable to access ANY survey database for edit. They can be opened read only, but the option of opening for edit isn't even available. The old computers we have CAN open the same databases for edit. We have attempted repairing/reinstalling, but to no avail. All the new computers were cloned from 1 original.

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 am bringing in the points by importing survey data because I don't want anyone to be able to edit the point data.
Vive noticed that they can be erased and that you can explode them.

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.

How are you or your company managing points as in field shots, storage, dulplicate point numbers?
are you using vault?
are you using the point database?
are you using one drawing file to import and store the points?
what we are doing now is using the point database as a storage location but it fails for notification on when a point # is duplicated.
surveys has a drawing file they use to import, store and build the existing ground surface from the points. this allows the notification of when a point number is duplicated. but it is not as secure or flexable as the old LDD way.
We don't use field books just text files from the collectors imported in. Vault is not an option for us. (at this time)
so what i am looking for is how others are adapting to this change, and what worked or not.

I am running AutoCAD Civil 3D 2010. I am a new user and just going through some tutorials and created a couple of survey databases for practice. The problem I am having is I can't figure out how to delete them. When I exit Civil 3D and restart it, those databases are still there under the survey tab in Toolspace even though I haven't even opened a drawing yet. Also, do I need MS Access installed on my workstation to run any functions within Civil 3D?

I have a survey figure that no matter what will not come in with the correct elevations, its a spline (continous) curve that the elevations get blow up on.
Only thing I can think of is the when it starts to interpolate the curve it cant get the elevations correct, this only happens in the curved area, once it goes tangent everything goes back to normal.

We have a template file for all of our engineering drawings. When we receive the topo from our survey department we insert the topo (as a block) into our Eng. dwg. Our Survey dept just did their first topo using 2012 and survey figures. When we try to insert the dwg the system crashes. I can XML the surface into the drawing, but I don't get the line work.

I am trying to adjust (raise) a very intensive topographic survey from NGVD 1929 to NAVD 1988.I know how to raise the surface and I know how to adjust the datum of the points.
How to raise all the breaklines used to develop the surface as well? This would include survey figures, feature lines and 3d polylines.I want to raise them all by an equal amount.

I have a drawing that is about a month old with survey data and a surface in it. I went in to modify the surface and noticed a crossing breakline message that was never addressed. I attempt to do a grip edit on the survey figure that is crossing ,and update the database from drawing and I get a message saying the figure is in not in the database. I know I have the correct database, because if I select the figure in the prospector tab It highlights the one I'm working with. Somehow the objects in the drawing have lost association with the database.
Any solutions short of re-inserting all my figures from the database? I'm not going to do that in this case since the edit was small and is already done.

I am trying to make a single point label style that will return a blank line in the label if no data is provided.
The way i have it coded now my label for a structure with only two inverts comes out looking like this:
STCB 500 Rim=300.00
12" CONC N IE=295.00
12" CONC S IE=296.00
IE=300.00
IE=300.00
I would like the number of lines returned to match the actual number of inverts in the structure and leave out the place holders.:
STCB 500 Rim=300.00
12" CONC N IE=295.00
12" CONC S IE=296.00
I can work around this by having a label style for each number of pipes, but i would also like this code to be inseted into a table style and in that case i don't know of any way to assign multiple styles to one table.
My current code looks like this:
RIM=<[Point Elevation(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
<[1 SIZE(CP)]> <[1 TYPE(CP)]> <[1 DIR(CP)]> <[IE TEXT(CP)]><[1 INV(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
<[2 SIZE(CP)]> <[2 TYPE(CP)]> <[2 DIR(CP)]> <[IE TEXT(CP)]><[2 INV(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
<[3 SIZE(CP)]> <[3 TYPE(CP)]> <[3 DIR(CP)]> <[IE TEXT(CP)]><[3 INV(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
<[4 SIZE(CP)]> <[4 TYPE(CP)]> <[4 DIR(CP)]> <[IE TEXT(CP)]><[4 INV(Uft|P2|RN|AP|GC|UN|Sn|OF)]>
LADDER <[LADDER(CP)]>
The problem is that 1 INV-4 INV are being defined by an expression that reads like
{Point Elevation}-{1 MD}
so when no data is intered for my UDP "1 MD" it returns the point elevation. I want an equation that says if rpoitn elevation -measure down=point elevation then no data is shown.

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.

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.
