AutoCAD .NET :: How To Add Contour Data
Sep 8, 2011
I've got a routine that gets the surface, I can rename the surface, get the min and max elevations,... But when i want to add a ContourData there is a problem.
I set up a SurfaceAnalysisContourdata (see code below), when I try to add the maximum elevation to the array I get the error "Object reference not set to an instance of an object"
Dim cdata(0) As SurfaceAnalysisContourData
cdata.Initialize()
With cdata(0)
.MaximumElevation = TextBox1.Text 'Maximum surface
[Code]....

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 am working on three different projects at once. For each project, I was sent a drawing with contours as polylines. Each contour is broken up into polylines about fifty feet long each at elevation 0. I am trying to set the polylines to proper elevation without editing each one individually. Each drawing contains several hundred polylines to modify. I was hoping for some sort of way to use a fence and interval (2') with a starting elevation.
I've searched the internet but haven't found a lisp routine to do this. I thought I remember Land Desktop having something like this, but can't seem to find it in Civil 3D 2012. I have found several threads asking the same question. Each time the poster was referred to a blog 7629. That blog unfortunately seems to have been taken down. If I can’t find an answer soon, it looks that my best option would be to retrace each contour which makes me glad to be paid hourly.

When I add contour data to my surface, I uncheck all the boxes in "Minimize flat areas by:" except "Swapping edges", and I check the "Swapping edges" box. The next time I add contours, I have to uncheck the same boxes, and check the "Swapping edges" box. I can set the default Mid-ordinate distance, etc. but I can't find anywhere in the settings that I can preset the check boxes for minimizing flat areas.

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 am trying to link my extracted data from blocks with attributes to an extenal source so that the table I create and place into the drawing already has the formulas I need to due the required calculations. But every time I create and place the table the formulas are not in the table. I include the columes that contain the data but it doesn't seem to be working.

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.

Is it possible to embedd data in a table so that a user can select from a group of data within one cell?
I use this technique quite often in Excel. One cell in a table can have various values: A, B, C, or D. While another cell can have a different set of values to choose from: BLUE, RED, ORANGE, or PURPLE. The user can pull down an arrow (similar to a dynamic block) and choose from a set list of values.

I know that the xmls are very important in the design data folder and we shouldn't mess with them.What about the rest of the folders. I have around 11 folders. GOST, AEC Exchange, AIT, Cable & Harness, Bend Tables, DWG-DXF etc...
I need to know if any of these folders can be deleted? We don't use AEC Exchange, Cable Harness, BIm Exchange, Design Accelerator, Tube & Pipe.
What about the Optimisation, DXF-DWG. I am not sure if I am using them unknowingly.Does this could be deleted? Is there a procedure to get rid of them.

how to import point data that has Map Object Data also attached to it? "import it by attaching to a data source".
Example: I have a bunch of manholes. Each MH has X,Y,Z, but also Type, Invert Elevs., Pipe Sizes, Pipe Materials, Pipe Directions, Structure Type/Material, etc. etc. etc. I may have point data representing MH's, airport runway ends, trees, anything you can imagine, with all kinds of data imaginable.
I want to import this data directly into Autocad/Civil 3D as either Autocad points, lines, or closed polylines (I also have utility lines, parking lots, etc.- all with data associated with it), all with the data attached as object data. I know that anything more complex than points might be hard to explain here, so I am hoping at least for a solution on how to import points - I have 99,999 MH's and obviously I don't want to have to type all that data in one by one.
I basically suck at using sql server. I can get around using the Map workspace and the different tabs. I have never used FDO, and I am not even sure what it is.
I fooled it today by creating 99,999 Autocad points at the correct XYZ, attaching the correct object data to them, then exporting as a shp file. I went into the shp_name.dbf file and edited it to add the data I wanted by cutting & pasting from Excel. then I re-imported the shp file. but, this is a workaround at best.
Surely Map can import objects and their associated data fields, all populated with valid data! all I need is to know how to do it. I mean, if this is not something I can do directly using Map commands should I take the money I earned by surveying 99,999 MH's with my GIS data collector that allows me to assign 101data fields to each object I survey, and buy something better?

Is it possible to add data to a feature data table? Example: The shape file data downloaded from NRCS only has the Soil number for the State. As I check out features I would like to add data for the soil name, soil group, etc. as additional columns in the data table and have it available in the future by checking the feature back in to my local information.

I have a drawing with Objects that have both Object Data and Linked data in an Access database. I need to get information from the linked table to a new linked table for each object.
I have thought that if I get the necessary information from the Linked table record to the object data for each object, I could then convert the Object data to a new link and am looking for a way to copy the data from a field in the Linked Table to the object data. There is at least one field common to both the OD and Linked Table record.
Is there any automated way to transfer this data?

I'm working in AutoCAD Map 3D 2008 and Autocad Civil 3D 2009.
The General Task:I want to convert the object data to attribute data so that I can export it to an Excel file, add another column of data, and then import that new data as attribute data.
The Specific Task:I have thousands of campus water meter locations (a block with a small icon, attribute data, and object data) that belong to two different systems, domestic water and lake water. Each of these blocks has object data item (a barcode tag) that I want to show as a label next to the block.
However, before I do that, I want to export that barcode data to an excel file so I add a column (eventually a new piece of attribute data) that says whether or not that specific water meter is radio read or manually read. I want to then import that radio read/manual read excel file back into autocad and have an X appear on the block icon if it is radio read. I also want the barcode information to show up as a label.
My problem:I can't get the barcode object data to export with the locations in one easy excel sheet that I can simply import after I have made my changes.
Find some person on here who knows how to convert object data to attribute data.

We have shape file that I imported to MAP 3D using map import, I would like to get the contour lines in 3D and then open them in AutoCAD general and see them in 3D (They must have a z value). How can I do that.

I am having difficulties with plotting labels on pdf. I am using 2011 map3d. I am struggling with labeling contours. Basically i have shape file which draws out isometrical lines, then i label contours, everything looks nice/works before plotting but when i plot it on pdf, it basically seems to do a selective plotting of contour labels (all the contours are plotted nicely). Some contour areas are covered nicely, some have only few left, but most parts have none.
My drawing is basically large tiff and shape file on top of it. Contour lines are covering slightly bigger area than the tiff file. contour labels that are actually plotted are mostly drawn on the bottom and left part of the drawing (plus they also seems to be somewhat following the vertical measurements, as if they are only drawn to a certain height or so), mostly out of the tiff part, but also partially continue on top of tiff, until are not plotted anymore. When i want to view contour labels on the whole drawing area, i basically have to "dr" tiff to back, altough drawing order is set so that tiff is drawn first and then other are placed. Sometimes it just boggles my mind why CAD acts like this. If it wouldnt draw any contour labels, i would understand, but it basically does it partially/regionally somehow and even then there are those regions, where labels are drawn only partially, but are still drawn.
It has got to be something to do with the size of the labels compared to the screen. At the moment size context is set to "map space" and when i look at the drawing in model, i can see all the labels nicely (they are drawn in absolute units and are not relative to screen). When i look at it in the layout (layout scale is set to 1 mm=1), i can only see lower part of the drawing covered in labels. As i increase the size units, it gradually draws labels to the upper northern part also.
I was suggested to export the contours and labels as a dwg,open it and then plot it, but what happens is that map3d seems to be able to export only 2000 items (labels). I am sure it would work, if i somehow could manage to export all the contour labels. I am going to add a picture also just to give a better understanding of the problem. Polyline marks the tiff image location and basically the black dots are the labels that are being plotted.
The thing is, that it actually copies exactly 2000 labels into text, which seems to be corresponding to the "rasterthreshold" command limit of 2000, is it just a coincidence?

I have a table setup in Autocad map and am entering attribute data for the objects (Polygons). I have received a new dataset which I imported as points into the drawings which sit inside in the polygons. The points imported include one attribute data field that I want to get into my table.
In practical terms I am entering data re building heights, received a lidar file with point data relating to the building height.

When generating a line of contour labels with Contour-Multiple, most of the labels are orientated properly but some of them on the line are rotated 180 degrees. Why aren't they ALL orientated in the same direction?
Also, sometimes, all of them will be orientated in the wrong direction such that they are, essentially, upside down. Is this a bug or is there a setting to adjust?

I have recreated two surfaces for my design, existing and proposed. I had used polylines for contours for in each surface. I tried labeling the contours but it will not let me select the contour itself.
I then tried to make the contours to 3d polylines and again added them to the surface and rebuilt. I still am not allowed to label the contour since it doesn't let me select the polyline. I am able to select the surface however.

When I create a grid from our OSIP DEM files the contours come in as a block. I usually do 1' and 5' contours. I would like to break these so that when I select a 1' contour it will show up individually with elevation data still attached. If you select one now, it selects the entire grid. If you explode it, you lose the grid file. Is there a way to do this or will a just have to label the contours so I know where I am at?

So I have finally been able to create a surface that I like and slice some 3D solids using this surface. But now I would like to draw some contour lines of that surface. I have seen some videos about creating contour lines (such as this one: URL.... ). But in this video they import the surface using the 'connect to data' button in the toolspace area. Is it possible to insert a surface from your drawing into the toolspace area and then draw the contour lines? I managed to insert the layer containing the surface using Data --> Add drawing data --> Drawing layer... but I cannot change style or create contour lines.

Unable to create contour labels
Issue You were unable to create contour labels. When you tried to create a single contour label, you could not select any of the contour lines of a surface. When you tried to create multiple contour labels, the contour label line disappeared after you selected the second point.

I have a plain 3d contour map with all the lines on the same layer.
I want to make it readable in 2d by changing the linetype of each so it's easier to read.
The map is pretty large, I was hoping there was some way I could isolate all lines with the same Z Vertex so I could do an entire elevation at once?
