AutoCAD Civil 3D :: Generating Base Map - Survey Code Offset
Sep 17, 2012
I am just beginning to use the Survey features in Civil3D 2012 to generate a base map. When we use the offsets, we are having issues when we have a negative number: BC ST H-.5. The line will not offset, it just comes in directly on top of the original line. When we use a positive number, it offsets correctly: BC ST H1.4 V.1. Is there a setting somewhere that needs to be changed for it to read the negative numbers?

Is there a way we can support a duel feature code ?In the field the surveyor would enter into his file “ EWD[*TB[“ .This code indicates the beginning of the “Edge of Woods” and “Top of Bank” .
Each shot after that would be along the edge of woods and top of bank . “EWD*TB” -- This code indicates shots taken along the “Edge of Woods” and “Top of Bank”
The surveyor would end this feature with “ EWD]*TB]“.This code indicates the ending of the “Edge of Woods” and “Top of Bank”

but in my condition,the base point is offset from the extended line .see the picture. how can I solve this?

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.

Is it possible to add a base depth to the transition lane assembly? I need to do volumes for my road, (pavement, base) but there is a section with a transition (which only has one depth), so that section is off.

I need an offset lisp routine to offset a selected line a set distance on each side of the selected line and change the layer of the offset lines to the current layer, and then keep prompting me to select the next line for offsetting until I'm finished.

I am trying to create a station-offset label style that will drop the trailing zeros in the offset section - e.g. 15' instead of 15.00', but if the offset is not at a whole number, e.g. 15.01, etc. it will display the entire offset.
I created two expressions: IF(OFFSET-TRUNC(OFFSET)=0,.1/12,.00000001/12)
and this one: IF(OFFSET-TRUNC(OFFSET)!=0,.1/12,.00000001/12)
I then created two offset components, one called truncated, and one called full, and assigned the heights to match the expressions.
I have attached the file, the style is ACHD-Sta Off-Rt [copy]

How would I go about generating labelled points with xyz values at 5m intervals along a road alignment in Civils 3D 2014?
I have had a go with the AddAlign Labels command but could not figure out how to add an elevation value to the label. Also this method seems to require manual input for each label which is not practical as I will have have around 450 points to set out.
I have looked into the Stakeout Alignment Report, but this seems to require a survey database, which I don't have.

What do I draw the existing pipes as that will be under the surface that I'm profiling? I have the surveyed invert points I'm assuming that won't be polylines? how to get the pipe to show at the proper elevation on the profile?

Is there a way to generate the station ranges for each sheet title block when generating sheets? It seems like there should be some sheet set manager variable for it or something but I haven't been able to find it.

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 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?

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.
