AutoCAD Civil 3D :: Choose Projection On Importing Points
Aug 9, 2012
I have a .dwg file with an AT-LCC projection assigned to it. There are some .shp files connected to it.
Can I choose the projection of to-be-imported-points when I import some laserscan-files in ASCII format? So I can tell AutoCAD: these points are in MGI-AT.AUT-Central/GK projection, please convert them to my desired projection.
There is a method which takes much too long:
open a new document assign the origin-projection (here; MGI-AT.AUT-Central/GK) to the fileimport the pointsexport the points as .shp file, define a projection-system conversion to target projection (here: AT-LCC)open the file with the target projection assigned to it (here: AT-LCC)import the .shp file
We have a points file to create a "bottom of peat level" surface. The only problem is, along with the X and Y, it only gives us the distance from OGL, not the actual Z Elevation at each point. How do we import these into C3D to create a surface? We have a topo survey for the whole site, so we have and EG surface.
When I import points from an external project point database (LDD) which I do quite often to import points from 2008 to Civil 3d it works fine for me, but when a co-worker tries doing it from the same exact drawing just a different computer it does not work. Whe he tries to do it, a red "X" appears telling him there is some kind of error. VERY strange and I have no clue why????
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.
When i import points (csv) from my excel sheet into Civil 3D, i can't see the actual points on the display frame, but i can see that the points have been imported by looking at the prospector tab > Points.
I am building a new template for our office and just finished building my Description Key Code Set, and Figure Prefix Database. I stopped to do a quick trial run on one of our surveying files, but when I imported the file all of the figure lines imported correctly but the points all came in the default point style and label style. I went to the Settings Tab/Points/Commands and made sure my "Disable Description Keys" was set to False. This is not my first template and I have never had this issue before.
We're moving [slowly, painfully] from LDD to Civil 2012. When importing a survey fieldbook in LDD, my method has always been to "clean up" the fieldbook during the import. Rather than search through the fieldbook text file manually, I'll let the import process find the duplicate, overwritten points, or errant linecodes, and then exclamate them or change them in the fieldbook and, if necessary, reimport the fieldbook. Figures and breaklines use the initial coordinate, for instance, so sometimes a reimport is (was) necessary.
So our survey crews "overwrite" points in the field for bad rod heights, angles, descriptions, etc... During the LDD import process that point number is flagged and I am given the option to overwrite/average/etc.... In Civil 3D I seem to be stuck with an average of the two observations, and I'm not even alerted about which point numbers come from these "multiple observations." So I've no idea without sifting through the often substantial list of point numbers which points have duplicate data connected to them.
I've combed through the import options and I just don't see what I'm looking for, which, in a phrase, is to be alerted when there are duplicate numbers in the fieldbook.
Our Surveyor created the Point Styles and description keys for processing our field work. These were incorporated in our template. Yesterday he brought in field work an noticed that only a few of the symbols incorporated into the markers came in.
The blocks exist in the drawing but when you go to edit the point marker only 8 out of 152 blocks show in the window below "Use AutoCAD BLOCK symbol for marker". I tried a backup of that template from 5 months ago and got the same results. I've verified that the blocks still exist in the drawing both by listing them and exploring them in Design Center. If I try other templates the window shows all the blocks.
I have tried Audit and Recover with no improvement. Thirteen errors fixed but the blocks still don't show. Additionally I found a backup of the template from Feb., 2013 and get the same problem but the lack of blocks only just occurred.
This is an example showing the depleted block list:
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?

I want to know why I can't change coordinate of points while importing points from Points menu?
I created new file, assigned any coordinate system to the model. Opened Import points windows there, created new file format which there I assigned Coordinate zone transform to the coordinate system of the text file and imported my text file. But the coordinates of points didn't changed or transformed. When I do it by Survey in Toolspace its works good. I want to know whether I did any wrong or it is problem of software.

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.
I just ran into a projection issue with a couple of AutoCAD files. There is a possibility that one of the files was originally in Microstation and in meters before it was converted to AutoCAD but I'm still trying to confirm this now. The problem that I am running into is that AutoCAD Map doesn't allow you to xref or attach other CAD files and use different projections. I have one file in Maryland State Plane, Feet and a second one which appears to be in Meters and I can't get them to overlay or for the file in meters to come in at the right location when it is xrefed.
Is there any way to project feature lines into a profile when the plan view is xref'd? I have my plan view "existing topo" with all existing features/Figures and a existing surface.
My profile is a separate dwg with plan view xref'd and surface a data shortcut. Of course there are feature lines and Survey Figures in the existing top I want to project into the profile, but can't because it is an xref. Besides copying .
if i have one feature line i want to project to all sections in a sample line group it would seem you should be able to pick the one line and assign in a label style and you would be done quick and easy. instead if you pick the multiple projection option you get this percentage distance box and it tend to grab stuff you don't want.
I am having difficulty projecting an existing feature line at a specified tie-in slope. I have a steep (3:1) feature line that I need to project at a specific slope (2.5:1)to intersect a surface model. When I create the grading object the generated grading object is not 3:1 along the feature line and 2.5:1 perpendicular to the feature line. Instead I am left with a new slope that is 1.9:1 between the generated contours. I have attempted slope to surface as well as slope for a distance.My design criteria is to not exceed a 2.5:1 tie-in slope.
I am re-routing a small stream. I am using generic links for the bed and side slope. I whant the side slope to be 3:1 and project beyond the existing culvert wall in the eg model. can this be done easily?

How to share custom projection files with multiple users? I created a custom projection for C3D on my computer, now I need to give it to several other people. Can't seem to find where this file is stored.
When we apply surface projection gradings to feature lines, we get locked vertices on the feature line wherever the grading transitions from cut to fill. In turn these vertices create segments in the feature line which influence any labels applied to the line. I don't want a bazillion segment labels on my FL. I only want segment labels between the physical vertices and elevation points. Is there a workaround or is an enhancement request in order?
I had to create a boundary map and place points to all corners. How to export these newly created points back into my data collector (Ranger) and also I'm trying to figure out how to print out a points list.
I stumbled on to this thread but I guessing that it's a different CAD year because my modify tab doesn't look like this. URL.....
I have recieved a file with many points and would like to convert them into COGO points in Civil 3D. The problem is; I would like to keep the hole ID's as I convert, I've made a few conversions and lose the hole ID every time (not showing in Name or Description). Is there a seting I am missing to keep these? My aim to to organize the COGO points in different point groups.
I am looking for grading utility in autocad civil 3d. So, i need to smooth my projection slope to target the surface without projection steps. The objective is to correct a surface to implant photovoltaic structures.
I have a couple points that were part of an import event (data from a previous project) which I want to assign as control points for an incoming traverse, is there any way to assign those as control points? I can't seem to find a way to do that other than perhaps re-importing the specific points as control points and overwriting the existing ones.
I have a project that was started by leaving all the survey data inside the "All Points" group. So, I'm concerned that when I enter my as built survey points, that even if I put them into their own group, that the original surface will still look at them and just rebuild to my asbuilt data, effectively cancel out the purpose of the asbuilt survey. Will this happen?
I want to take the original points and put them into a group of their own, but I don't know if that will affect anything or not? I have several wetlands already designed on that surface with volume calcs already done too.
