AutoCAD Civil 3D :: Data Referencing And Coordinate Transformations
Aug 10, 2012
I have 50+ project sites scattered along a 600+ mile alignment. My alignment reference drawing coordinate system is set to a UTM coordinate system. My project site drawings are set to state plane coordinate systems. Does coordinate transformation automatically occur with data references?

I want to create a live instance of an existing FG-Profile that I somebody else did into our master profile drawing. Is there an easy way to do this? I don't want to data reference it in.
I tried exporting the FG-Profile information into a .txt file and then use the "create a profile from file", but for whatever reason C3D didn't like my profile info was giving me an error message.

When I try to reference an object in the Data Shortcuts menu, when I right-click the a profile in Prospector under Data Shortcuts, the option to "Create Reference..." is grayed out, and I am unable to reference that profile into the drawing I am working on. It works fine on other profiles that are being referenced from the same drawing.
I have tried:
1. Re-creating the alignment and profile data shortcut in the drawing being referenced
2. Creating a reference in my drawing to the alignment, which actually works. However, it still does not allow me to "create reference" for the profile.
3. Refreshing the data shortcuts.
4. Synchronizing the alignment referenced in the drawing.
Nothing seems to work. My only other option is to move the C3D profiles from the referenced drawing to the drawing I am working in. Is there a way to do this?

I have an Map that was drawn in regular autoCAD drawn 1:1. I know the coordinate system that I need to assign to it and some known coordinate but how to I go about getting my current map to be correctly Geo-referenced.
Is there a way to tell AutoCAD map that a certain few points are at certain coordinates, and the rest falls into place?

I have a problem with different coordinate systems. I have a drawing in old Finnish coordinate system (KKJ, kaista 4) and I have a point file, which is made in ETRS-GK29 coordinate system. When I try to transfer the points to the drawing, the points will land way off from the drawing or I get this error message "Coordinate transformation from ETRF89.FinlandGK-29 to FINL-KKJ4 failed for point located at {29511662.554000,6948599.365000}. This usually indicates the point falls outside the boundaries of the destination coordinate system". I have checked and the point {29511662.554000,6948599.365000} should be over the drawing.

We are starting a project that we will be preparing a site grading plan for.We are being provided with an ALTA Survey drawing that is on state plane coordinate system, and the existing topography that I will be using for my existing surface is on a UTM coordinate system.
The site grading plan needs to be on state plane coordinate system that the ALTA Survey drawing is on.
I haven't done it before but I understand you can use Map 3D and take drawings that are on different coordinate systems and have them line up properly.
If I have my existing surface in a UTM coordinate system and want to data shortcut it into my site grading plan that's on state plane coordinates, will that work?

When the attached shape file (change soilmu_a_a.txt to .shp) is imported using MAPIMPORT the data aligns with other imported georeferenced raster imagery (said imagery was imported using the MAPIINSERT command). If the same shape file is imported using the data connect tool it shows up in a much different location (see word document).
The drawing coordinate system code is "UTM83-18F" and the data was downloaded from the Web Soil Survey's data download with the identical coordinate system (see attached readme.txt).
I prefer to use the data connect option when importing this type of shape file because I can label them all using a theme and use stylize the data for visualization/presentation.
As an aside, I have found that data connect does not automatically transform data coordinate systems to match your drawing coordinate system as advertised. I've used the edit coordinate system to no avail; however, again when the file is imported using MAPIMPORT and saved as a drawing (with native data coordinate system) and then that drawing is queried from a drawing in a different coordinate system it seems to transform the coordinate system just fine. Is this a problem with data connect?

when I import PNEZD format .csv using import wizard the coordinates get transformed. all points are shifted about 20' in northing and 5 feet in easting. I have to use the import wizard w/ survey database in order to process linework codes.

I have Lidar LAS files in UTM18 and need them in State Plane. Horizontally they come in fine to a drawing with the correct system set. Vertically they are still in Meters. I know a couple of workarounds. But I'm just wondering if there have been any advances in 2014.
We're still on 2012 but I'm testing 2014 I don't want to go through the whole process again if it's not going to work.

I work in a manufacturing facility and we are trying to come up with a way to extract data from an AutoCAD file in to a .KML or .CSV file which gives coordinate points, etc.
This will be used in a mapping-type software to display/highlight areas of the plant with zooming capabilities and information shown on the left-side. We are trying to make it look something like Google Maps, so it can used to determine areas of the plant undergoing work, lighting zones, etc.
In a nutshell, I want to be able to extract coordinate data from our layout(s) which can used to pinpoint locations on the map and highlight regions, etc. Perhaps it could export data in to Excel with attributes assigned to the coordinates which give Area, Bay Location, etc. The initial thought was to somehow export this to a .KML file and use that as a starting point.

I have acsii data that I need to add to a map. My coordinate system for the map is CANA83-3TM114
The coordinate system for the ascii points are unknown. How do I transform the data to the same coordinate system as my map?

I have been provided survey data in the form of an XML file that I am using to build a surface. Everything is fine, except for the drawing with the surface is still referencing the XML file. What is the best method to remove this reference and have the surface fully contained in one file? Using C3D 2012.

I have a master shape file that contains parcel ID, owner, tax info., etc. I have another file ( access 2003 -open to better file format suggestions-) which contains parcel ID and a "yes" or " no" entry for whether or not the parcel needs a new water meter. All I want to do is add the water meter information into the other shape file. This would create one shape file with one table with all the information that I need.
Ultimately I will use the information to do a map query and find out spatially where i need new water meters.
Right now i have the master shape file connected though the “Connect to Data” feature. I also have the new data added to the drawing though the Data sources------>attach under the “Map Explorer” Task pane. I attached access file (ver. 2003 .mdb) which has two columns “Parcel ID” and “Meter”.
I right click on the shape file under the display manager and select”Create a Join;” however my water meter table is not listed as an option. Will this not work?
Plan B - I tried to Create and connect to the access file as an ODBC connection. Followed this guy’s directions to a T [URL]. But when i populate my table under the fdo connection the column headings exist ( “parcel ID” and “Meter”) but the actual data is missing. Am I missing something important?
Note: I am running c3d 2012 on a Win 7 64 Bit machine. I also removed office 32 bit apps and installed 64 bit apps to see if that would solve the problem. No go.

say you make some parcels in your project with custom data fields like: id_no, permit_no, acres_served etc. you attach an agency provided shape file via an fdo connection that has many fields of information like above.
when you right click on your parcel and do parcel properties you get a tab that lets you input the custom parcel data.
lets say you print an fdo map label showing, say, the id_no, provided in the shape file. Then in your custom parcel properties for id_no you type that in.
is there a way to make an expression to put in the other custom parcel properties that will read, say, the permit_no(id_no) from the fdo like and put that information in the custom parcel property field?

I'm having problems getting super elevation data to transfer to different drawings by means of an alignment data shortcut. I know alignments hold the super elevation data so I've gone into my alignments data shortcut, input my super elevation data, saved and closed. Now when I open my finished grade drawing, reference in my alignment and profiles, then create a corridor from that information, my super elevation didn't transfer with the reference.
I pulled cross sections and it appears is has no clue there is any super elevation data. Also, I tried bringing it directly into the drawing I'm doing my corridors in and it erred saying I must be in the parent alignment drawing. Data shortcuts are pretty much useless to me if super elevation data doesn't transfer.

i have created a data band in profile view that should show a created profiles elevation, but some of the the data fields are missing irregulary. Also in the data band that shoud show the diferenece betven the tow profiles - EG and the new profile the data is missing. The EG profiles data and the surface are ok all is shown.

I've just installed Civil3D, 64-bit on windows 7(running on bootcamp) and am trying to insert a georeferenced raster image but have encountered some issues.
1. "Home tab>>Data panel>>>insert An Image" - The data panel is missing and it's also not found in "customize palettes"
2. Trying the data connect route does not work either: Display manager>>>Data>>>Connect To Data - There is no 'Data' option and I cannot connect to Data.

How do I add my own system in Civil3d? We have a little strange system here with a deformation model, but I suggest that isn't a problem.

I'm finding myself on more and more sites that use multiple coordinate systems and height datums.
We have 3 on this job. One is the MGA zone 50 GDA94, another is just an offset of this and the third is a strange local grid with offsets and rotations.
We have Excel spreadsheets that can convert between the systems, but that requires several extra steps per point.
Is it possible to define each coordinate system in one drawing so that I could select which system I wanted to use, input the points and then select the main coordinate system so it converts the coordinates directly? It would mean less steps and I would have greater confidence in this system.
We have the parameters for all systems.

Each time an @ is entered at the command line, C3D is freezing for up to 15 seconds before allowing the comand to continue. It wasn't happening last week and no changes have been made to the instalation. What could be causing this glitch?

If I set up my Civil 3D drawing in some known coordinate system, e.g. State Plane, in the "drawing settings", can I then toggle my drawing into other known systems, e.g. UTM, by changing the coordinate system under "drawing settings"?
If not, how are the coordinate settings used?

I want to have a piece of text added to the drawing notes that uses a field (or similar), to list the coordinate system code assigned to the drawing, i.e. UTM83-12.
Any setvar or something that I can use?
There are load of different coordinate systems to choose from, and I don’t want to have to manually enter it for every drawing.

My group is trying to convert a dwg from one coordinate system to another. The original drawing contains points, blocks, etc. in 1 system and we need it in a different one. We tried attaching the dwg to a new map with the new system using a layer query, but this did not appear to bring in the objects into the new system.
"Structures" is in the original system (OR83-NF), "StructuresHarn" is in the desired system (ORHP-NIF)

I am using Civil 3D and Map 3D 2010.
I have some points in a drawing set up in a coordinate system and using a specified point file format, I successfully exported them to another coordinate system for use by our surveyors. I also wanted the pipe route in my destination drawing so I created a shp file from a polyline representing the pipe route in the original drawing using Map 3D Export. When I imported the shp file into my destination drawing there appears to be a slight horizontal difference from the point locations. The shp file doesn't land directly on the points.
To try another comparison, I ran a query on the pipe route to perform a manual coordinate system transformation. The result of this is the exact same as the shp file.
My questions are, which method (exporting points vs. shp files) results in the correct coordinate transformation and why are they different? When exporting points I am not using any specific transformation settings, I am simply selecting the destination coordinate system. When exporting a shp file, Map 3D creates a prj file from the specified coordinate system in the drawing. Are there any other settings I need to adjust to get the same result with both processes? The only thing I can think of is I only have the coordinates out to 4 decimal places in my point file format, do I need to go out farther?

Is it possible to turn off or disable the coordinate or drawing conversion on import. I know I can turn it off in a dwg file but I want to completely disable it no matter what the setting is in the dwg file.

My Civil 3D 2012 coordinate systems normally displayed on the units and zone tab of the drawing settings have disappeared. On existing drawings the coordinate system code is still displayed. On new drawings the code appears as a symbol - a period or a comma or something. I can enter the coordinate system code and the program recognizes it.
My Civil 3D 2011 coordinate systems display as expected.
