AutoCAD Map 3D :: Exporting DEM Surface (terrain) Data As Shape
Nov 8, 2013
I am rarely new to map 3d. What I would like to do is to export 3 dem surface in any kind of format, so that I could open it in 3d max.
I know how to generate Contours, but when I export them to dwg and later open in autocad architecture there are missing info on z coordinate - so everything is flat.
Is there some way to make .3ds file or .dwg file so that would really look like a 3d terrain in ACAD architecture or 3d max?

Are there tutorials for AutoCAD Civil 3D 2012 that assumes that the user never use AutoCAD Civil 3D 2012? Maybe a step-by-step tutorial. I tried the online tutorials on this website but I find them a little bit confusing. If I want to create 3D model of a city, what's the best way of creating 3D model of the city? I thought that one way of creating a city is:
1. Create terrain using DEM data.
2. Create streets, roads, highways, train tracks, etc. <- I need better tutorials.
3. Create buildings.

I am using Autocad 2013. I need to fuse a square building which is placed on a sloping terrain. If the terrain was flat, i would have no problems. But how i can put a perfectly square building on a sloping terrain without having any gaps in between?

i´m looking for a workflow to import Digital Map Data from a source. The Data we´re using comes from Geographical Institutes. The File-Format i have never heard of:
-binear DGM *.dgm
-*.adf
-ASCI GRID *.grd
I dont know how to convert it to a mesh or something that i can import to MAX. The free plugin, called "Terrain" on Maxplugins, can import files like *.dtm or point clouds but not our Digital Map Data.
Any simple workflow to import such Heightmaps into max?

I am trying to animate a spline or jointed border object over an irregular surface.I want to add particles to the spline in the end to try to simulate a fire burning outward across a terrain.
I tried booleaning out a border and while that works, when I add particles to it, it overwhelms my computer. I tried using shapeMerge but that doesn't quite do what I want either. Itoo's glue plugin conforms an object to the terrain but doesn't allow me to animate it.

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.

I'm trying to export a surface as a DEM so that I can import the object into Bryce 7.1. I have a number of sample DEMs that I have downloaded from USGS site that import into Bryce quite nicely. These samples also import to another DEM reader named "3DEM Version 20.7." I'm able to import into Bryce when I set the grid at 10, but the quality of this surface/object is not very good. The DEMs from Civil 3d are referred to as "USGS DEM"s, but they do not load on common DEM readers such as Bryce or 3DEM software. Any way of converting a C3d DEM to a USGS DEM that one of these other readers can import?

I exported my surface to xml, then imported it into a blank drawing and the two surfaces looked different. The new drawing surface appears to be ignoring the surface. So after reading a post on here, I went back to the original drawing extracted the border and attached it back to the surface and tried again. I can not seem to export a surface and have it import with the same look. To be clear I am not talking about styles, I can not achieve the same definition look.

If there is a way to export a CAD file (dwg) to a shape file that can be imported into ArcMAP.
We use AutoCAD 2012, and do have Civil 3D, however have not used it (all of our dwgs are with CAD, not 3D).

We have an "original" existing surface of a ditch, a massive ditch. dredging has taken place and now we have a new existing surface of the ditch. the client wanted to see the delineation between the areas that are now 3" lower, 6" lower and 9" lower (and so on). I was able to do this easily with elevation banding. now the client would like some sort of GPS uploadable based on the color map that shows the banding. How to accomplish this without having someone set there and set points along the different colors on the surface. that is going to be incredibly time consuming. is there an automated way to export the data that I am looking for?

Can you take text from a drawing and export it out to excel? My thoughts are room numbers, employee names, department names, etc.
I need an excel spreadsheet showing this information to then upload to my CAFM Application? Is there an alternative to obtaining a report from a drawing?

I have to convert my ACAD drawing to shape files for a GIS user. I have figured out how create a polygon, point or line and add object data with the tables. I have my ACAD drawing setup to the requested coordinate system but when I send them the shape files they are telling me that they get a error in ArchGIS stating "an extent that is not consistent with the associated spatial reference information". I am using Civil 3D 2012.

I would like to know how to export a hatch shape as a shape file so that it can be used in ArcGIS. I am running C3D 2013 with Map 3D and ArcMap10. I have tried the Output as SDF and the map3d export and I haven't been able to get either to work. I don't have a problem exporting lines, points or polygons.

I do a lot of hydraulic modeling and create river bed surface datafrom surveyed points. I need to be able to transfer the surface data from Civil3D to GIS effectively. The issue is that GIS does not maintain the fidelity of my surface based on the breaklines I've drawn. It triangulates based on vertices and often triangulates through the feature lines. In LDD, I was able to do address this by adding vertices to my 3D polylines in a batch-type function. That is, I could select all of my 3D polylines and add vertices to them at the same time. In Civil3D, I have to add vertices to each feature line individually.
Any way to add vertices to feature lines, or to a surface, in a more efficient manner that maintains fidelity of surface data in the transfer from Civil3D to GIS?

I am learning to use surfaces in drawing, My main aim is for volumisation tasks. I had been following a tutorial that relied on creting surfaces. i.e
1) from the home tab> Surfaces> Create Surface
2)Add data. From Modify Tab>Surface> Add Data> Point Files.
This worked for me to start with but after changing some settings (looking to display a missing toolbar, I clicked or unticked one or two boxes, Not sure where, I know silly!). The only options I have in the drop down from "add data" are: Boundaries and DEM files. All other options in the list are not clickable.
What setting I need to change or perhaps restore all settings to default. Any comments on volumisation (spoil heps, Data is x,y,Z from survey equipment.

I'm really struggling with exporting a surface to XML.
I made a surface in which I paste all relevant corridor surfaces for the subarea of the project.
The surface looks OK in the file, but when I export, the XML file ignores my few edits, and adds excessive triangulation between adjacent corridors.
I already tried with adding boundaries, creating snapshots, exporting to XML 1.0 1.1 1.2, and regardless of what software I use the resulting XML, it looks crap, and the drainage team is struggling to work with it.

We are creating property set data and attaching it to polylines in autocad 2011. export the drawing to the older format (2007) and maintain the property data connection. We don't have and old version anymore so I can't test.

We're moving to Trimble Access on the survey data collectors which means that we have to export design data using Trimble Link and then use Trimble Business Center to examine the data and do any editing before sending it to the field.
So far I've found that alignments, profiles and surfaces seem to transfer OK. Corridors however have been an almost total failure.

I wanted to get a few opinions regarding exporting data.
We are working with AutoCAD 2013 Vanilla.
We have dynamic blocks with attributes that contain the block Name, Size, Color, material etc...
What is the best way to export the information?
Schedule and linked to a spreadsheet?
(I have experience with schedules but not so much with linking to spreadsheets)
DbConnect? (I know very little on this)
Another way to ask the question;
What is the best way to export the data that I can successfully train 20 designers on how to do it correctly.
So part one is determining the best method,
part two is training a group of designers to use it correctly.
I worked on getting a schedule out and linking to a spreadsheet but even after talking to my reseller support I feel that is too cumbersome. I would like a more streamlined process, you know the one, click here and presto!

I found out you can export the data table of feature properties from an SDF connection by choosing Options > Select All and then Options > Export and obtained a .csv file I was able to bring in Excel...but there are no headings for the data. How to export the column headings as well?

I have created a data shortcut to a surface using Civil3D 2011. When I create a reference to it in another drawing, it shows up in the Prospector but nothing shows up on the screen. I have played with the surface style and made sure all the layers were on and tried closing and reopening the drawing.
I have also tried to reference it into a brand new blank drawing and I even tried to reference a surface in a different file that I have referenced several times before (in 2010). Every time I get the same results. It seems like the surface is there, but I just can't see it.

A GIS person has asked me if I was able to convert a Civil 3D surface they have received into raster data files so she can use the data with ArcGIS. Just wondering if this is possible with Map3D? She normally gets someone in another office to do it, he uses an ArcGIS addon to take the data of the surface and converts it. The result is a bunch of ADF files and an XML file.

I have a surface made up of gradings and feature line that I had to come back to and edit. I picked the surface and selected go to source file and when I got there one of my infill's has gone missing and the surface has a big hole in it. The weirdness is the sheet file that refs it does not have the hole. What is that all about.
P.S. Editing a surface built up like a Rube Goldberg contraption is no fun at all. Glad my best practices are coming along since

I am working in Civils 3D 2014 and I have a survey with points already on the correct elevation layer, I have tried creating a surface from this but it does not show up.
My process:
- I create a new drawing and insert a block (my topo survey) and click explode when I do this
- I create the surface by TIN and make sure I have the correct layer for the points that I am selecting
- Click ok
- Then go into that surface and turn on all layers and refresh - still nothing
- I also made sure that my surface style was 1m contours so I would definately see this.

I have created a contour layer in MAP and need to bring the data into Civil (to create and EGL surface) which I usually I do via an alter properties query.
There is the Create Surface from GIS data in 2014 but this requires shp files so the two questions I have are:
Can the contour layer be output as shp files (and if so how)?
If yes, is this easier/more efficient than my current workflow?

I am trying to import a Shape file and extract the attribute data associated with the 'lines' (sewer pipes) into text format.
for example a pipe has an attribute showing the pipe diameter and intead of having to manually type it out I would like a way to extract that information.
Is there a way to do it? Whether using a specific method during the importing of the Shape file or another process?
*I use AutoCAD Map 3D 2011.

I am using AC3D 2014. I have created a surface from downloaded DEM points, but, as expected, the contours are not as accurate as I would like. They vary from known elevations anywhere from a few inches to several feet.
I also have survey data from approximately 500 points which include Northings, Eastings and Elevations. Is there a way to add these points to my existing contour surface and incorporate these know NEZ points such that he contour surface is more accurate?
I have already converted my "known point" file to a .txt format with comma delimited information.

I'm looking for a solution to export surface finishes into Excel. We built an assembly and parts and their faces has different colors. Is that possible to read colored faces, merged them by color, read the total surface area and then export into Excel. That is for estimating purposes. I read the thread "Extracting Surface Finish Data" but I didn't find the piece of code that I need.

I'm working on a topo survey and the contours are crossing each others (See attached pic) and what I did was edit the surface by adding points. I know that these points are fake, but how does this affect the terrain surface for design point of view? I did try swapping edge and deleting lines but makes it worse. Also as you can see in the pic, I don't see the added points like it did back C3D 2008.

I have a 1 mile road topo coming up for design purposes. The curb is standard, but there is full curb & depressed curb. If you had your way from the CAD seat, what shots do you prefer?
Most accurate I've seen iis Centerline, Edge Pavement/Edge Concrete Gutter, Flowline Gutter, Face Curb, Back Curb. More fieldwork, but made a good product.
What I have seen is CL, EP, BC, then "let them just use a template" and several variations thereof.
I have never seen a good way to automatically offset from say BC only and handle depressed curb by field coding.

I have a Surface that is data referenced into many different drawings. On one of the drawings, the reference will not show contours until I sync. It will show the boundary. Just one of them...but I can't use sheet set manager to publish drawings since I have to open it up and sync. Is there a setting we changed? The styles are all the same. The surface is on C-Surface, the boundary is on C-Surface, the Contours are on C-Surface-MJR, C-Surface-MNR.
