AutoCAD Civil 3D :: SHP File Data Connect Imports To Wrong Coordinate System

Jul 11, 2013

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?

AutoCAD Civil 3D :: Using Transform Coordinate System And Data Shortcuts?

Mar 21, 2012

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?

AutoCAD Map 3D :: 2012 Coordinate System Scale Factors Are Wrong

Jan 2, 2014

I was recently setting up a new install of Civil 3D 2012 and was going to set the default coordinate system to 3TM (CM=114°W) when I realized the scale factor was set to 1.0 at the central meridian.

It should be 0.9999. I checked some others and they are all the same. I also checked the 6TM projection and it is also set to 1 although it should be 0.9992

Below is the WKT(ESRI) out of Civil for EPSG code 3401:

PROJCS["CANA83-10TM115",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137.000,298.25722210]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",0.000],PARAMETER["False_Northing",0.000],PARAMETER["Scale_Factor",1.000000000000],PARAMETER["Central_Meridian",-115.00000000000000],PARAMETER["Latitude_Of_Origin",0.00000000000000],UNIT["Meter",1.00000000000000]]

Looking up the .PRJ for EPSG 3401, the published standard is:

PROJCS["NAD83 / Alberta 10-TM (Resource)",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",-115],PARAMETER["scale_factor",0.9992],PARAMETER["false_easting",0],PARAMETER["false_northing",0],UNIT["Meter",1]]

AutoCAD Civil 3D :: Insert SID File Using Data Connect

Jul 26, 2013

I am trying to insert an Mr Sid file using Data Connect. I am running 2011 C3D. When I try adding the file to the dwg, it tries to execute the query, but then I get an error "There was a problem adding data to map."

The folder containing the SID file has two other files...the .sdw file and the metadata file. Is there another file missing? Or is the SID file too large...it's 1.6GB.

AutoCAD Civil 3D :: DWG Coordinate System Transformation?

Nov 20, 2012

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)

AutoCAD Civil 3D :: Custom Coordinate System Failure?

Jun 7, 2012

I think this problem started after installing C3D 2012, and I don't think it's related to the UAC problems.  I tried asking my reseller about it, but got no answer. 

This happens with all projects that use Custom Coordinate Systems created in C3D 2011 or earlier.  When opening the drawing and going into "Drawing Settings", I get this, and have to click seven times through the error box to finally have it do nothing:

Then, if I go back to Drawing Settings, I see this:

Notice how most of the dialog box settings are missing.

This stuff all worked fine for years, but seems to have gotten broken as soon as I installed C3D 2012, and is still broken in C3D 2013.

AutoCAD Civil 3D :: Coordinate System Not Assigned In 2013

Jan 3, 2013

When assigning a coordinate system to my drawing in Civil 3D 2013, the drawing does not retain the selected system.

I choose the coord system I want in Map Setup and apply it (in this case MT83IF). After applying to the drawing I go back to verify the selected coordinate system and the dialog box indicates "N/A". The only workaround I can find is to save the drawing back to an earlier version and open it on another computer in the office that is running 2011. There I can assign my coord system and then reopen in 2013 where it now shows it properly assigned.

I have tried other coord systems to make sure it isn't isolated to just the one I am selecting - and it happens with all others I try. I have also tried a repair on my install to see if that would correct it to no avail.

I have a 64 bit system and have installed all service packs to date.

AutoCAD Map 3D :: Nearmap Image File And Correct Coordinate System

Sep 17, 2013

Nearmap has provided an aerial image georeferenced in the same coord system as Google Earth (epsg:3785).  I found a Map 3D coordinate system WGS84.PseudoMercator (epsg:3857) which on web forums is equivalent to epsg:3785.  After loading the image into a dwg on the epsg:3857 coord system I then queried the image into a dwg file on an mga55 gda94 coord datum.

It rotated the image correctly but as we had survey located features in the drawing the image needed to be shifted a further 1.75 metres SW than the transformation that Map had performed.

My question is to confirm that the Map epsg:3857 is indeed the same as epsg:3785?  Given I had to shift the image I suspect it isn't.

Nearmap have also suggested using an epsg:900913 coord datum but there isn't one in Map 3D.

I have successfully  exported the .shp file geometry previously but the cordinates system doesn't seem to match ARCGIS data sets.  I am trying to establish is this an Autocad or ArchGis issue I suppose.

AutoCAD Civil 3D :: Unable To Assign Coordinate System When Importing LAS Files

Aug 8, 2012

I have been trying to import LAS files via Civil 3D 2011.

To do this I first turn the workspace to ''Tool based geospatial''. Then i assign a global coordinate system which is the same one as the LAS file i am importing. The in the task pane window (command: mapwspace) under display manager tab i right click on map base --> data --> add point cloud data --> create new index and then choose the file I want to import. Here i have some trouble; in the create new index window i am unable to assign a coordinate system, i can find the one i need but i cant select it (or any other), it persists on staying unselected. I am able to create an index without a coordinate system but I need it with the right coordinates.

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.

AutoCAD Civil 3D :: Data Connect And Transformation Settings

Jul 29, 2013

I have geotif images that I've purchased from Washoe County GIS. They have world files that work great with data connect. That is, as long as I want to work at sea level. We have a Combined Factor mandated by the County for all record maps. it's a simple grid to ground factor. I can set this factor in the drawing settings and import my sea-level coordinate files just fine. The pboblem is that I can't get the Data Connect to work with the transform settings.The problem is the same with Geotif files and SHP files. I've tried using an x-reference drawing to insert the Geotif and then scale up the geotif but the imagery doesn't scale up.

Is it a program bug that keeps Data Connect from recognizing the transformation settings?
