There are only a few options to get attributes from ANY gis system into autocad. use FME (safe software) and export to autocad map / with object data. This would require the dwg be used in autocad map3d. and procedures below would apply from the open new blank drawing on. Use autocad map 3d to import the shapefile (or other gis format) and select ...

You can analyze polylines in amazing ways by using buffers. This is usually inefficient--buffers create many additional vertices--but (a) it is a technique available in many GISes (vector or raster based) and (b) it sometimes can produce information that is otherwise hard to get. In this case, buffering the road by a small amount and then buffering by the ...

If you have the roads in a spatial form, such as a Shapefile, you can load them into PostGIS and have it automatically find those using an SQL query. I've done this before - the SQL statement is designed to find for each road those that intersect geographically and create a nodal point for each crossing. I will try to clean this up later, but here is the ...

I partially agree with Devdatta Tehngshe, Map3d was designed at rel2000 specifically for heads-up digitizing. (This has gotten much more sophisticated in recent versions.) Argis 10 now has some features which make it "more" usable for that. I have map3d and raster design I use to geo-reference images and save to geo-tiff which I use in all my ...

AutoCAD Map is prefect for cleaning dwg files (spaghetti vector data) and preparing them for import for GIS applications. Also it is very good for georeferencing vector and raster data which can be pretty tedious in some GIS applications (not all of them). Generally, it is used for preparing data for GIS. You can us it as a GIS application, but it lacks lot ...

Expanding a bit on Marinheiro's answer: Even if the CAD data is georeferenced, there might still be some significant work to do to make it useable. I've often recieved CAD data that has georeferencing info in it, but the draftsman (or whoever produced it) simply ignored that and drew features all over the place. Then I have to manually align the features ...

if they are drawing in just autocad, you will be relegated (restricted) to planar equal area coordinate systems as the output. if they are drawing using autocad map3d then there is at least a chance that the drawing is in an actual crs to start with. if 1 then you wil need to move, rotate, scale the dwg using a known point as "base point". I ussually do ...

Yes (if you have time to watch the video) "Show me how to bring in data and reproject it" (video at the bottom) http://docs.autodesk.com/MAP/2010/ENU/AutoCAD%20Map%203D%202010%20User%20Documentation/HTML%20Help/index.html?url=WS73099cc142f48755156818d10b290e6faa-7fe1.htm,topicNumber=d0e206720 video link ...

All depends on your data. If your data is unstructured in dwg, then converting into shapefile will fail. For example, if you have polygons that are not polygons (closed polylines), but lines and polylines, then you will not be able to export them into polygons in shapefile. In that case you would have to create topology in AutoCAD Map which is out of the ...

Perfect job for FME (www.safe.com) and with it you could also split your data in grid. It's very easy if you use the TILER transformer. You would have many DXF, but at least they would be workable. And FME is less subject to crash for this kind of job. Note that FME has a demo version.

Given that your autocad version is 12+ years old it may be an issue with autocad dwg or dxf file format version (major format version: http://en.wikipedia.org/wiki/.dwg#Version_history). You should try to open it in a newer version of ACAD, or try saving it into an older format.

QGIS does not manage Z coordinates importing CSV files. You can convert the CSV to DXF using ogr2ogr from the command-line shell. This should be already installed since QGIS uses OGR too. You need to create a .vrt file along your CSV. This is a plain-text file that you can create with any text editor. It is really easy in your case: ...

I do not think there is a easy way to do this since the geometry types are different. You have two options though: Model/create the symbol in ArcMap Symbol Property Editor. You really can almost make any symbol by stacking/rotating/sizing various symbols together, see e.g. below You could also just take a screen capture of the polyline graphic, ...

I agree with @whuber's comment that moving parcel geometry to try to match area values is a bad idea. Since GIS features and layers are only representative of "the real world" it is often difficult to make the digital geometry match the on-the-ground features. To me, your best bet is to stick with the geometries that are provided in the DWG (which were ...

Have you tried using ogr2ogr to convert the shapefile to DXF? It is quite powerful, writes to DXF, and is free to use. Supported formats You can download FWTools to make the install process a breeze.

While ArcGIS has a variety of powerful analytic tools, AutoCAD Map 3d offers a wide range of ways to convert from GIS features to CAD objects and vice versa. It is very good in collecting a huge variety of data on both geographical and project data, it is definately more interoperable compared to ArcGIS. It provides an opportunity to directly edit more types ...

Yes, you could do this with FME for sure. There are many "transformers" that handle cleanup, intersections, and topology; I would try the TopologyBuilder transformer in this case. Any scripting is all done in a graphic environment, so it is very simple to do. You can always get a trial version from www.safe.com (Disclosure: Mark Ireland, aka FME ...

Try this to import .SHP to AutoCAD and separate distinct attributes onto different CAD layers... In AutoCAD : Map-->Tools-->Import (or at the command line type MAPIMPORT) Select your .SHP (or .SHPs – you can bulk import) In the Drawing Layer column of the Import window, click the ellipses on the right-hand side of the box... Use the ‘Use data field ...

the two things you are asking for don't go together. If you want the layout it will ONLY have paper coordinates. If you want real world coordinates it will never know the orientation of your paper (or layout). The work around would be to get the data in the dataframe exported (using the export to cad function for each data layer you want in the drawing. (you ...

You can use AutoCAD Map 3D to reproject DWGs. The transformation of the datum is supported in this process too. The steps are well documented in AutoCAD Map 3D help: Use AutoCAD Map 3D > Task Workflows > Work with Coordinate Systems > Transform a DWG File to a Different Coordinate System Here's a summary: Create a new DWG Assigning the target coordinate ...

You can have a look in GvSIG (OADE version), it starts to have good build-in tools for CAD, so : it has a command line tools to edit every points (with some topology functions) it opens .dwg, .dxf and .dgn files it generates world files for raster georeferencing it integrates like Kosmo, Sextante and now Grass for the OADE version so you can make profile ...

Symbology and labeling engine is not nearly as robust in Autodesk Map. If you want to produce nice maps with quick cartographic representation then it's tough to find a product like Arcmap. I edit vector data in Autodesk Map 3D often as opposed to ArcMap - quicker with fewer mouse clicks although I use both.

I took courses for both programs, and during saw the use of MAP 3D applications easier than Arcgis (for Engineer) of the following aspects: 1- Drawings (lines, points, polyline, polygon,....). 2- cleanup drawing. 3- working with Survey data. 4- working with Raster Image. 5- Data Conversion. 6- Data editing. 7- Data management. 8- Styling and Theming ...

The main advantage as compared to ArcGIS is in digitizing vector data. I have seen that on average, completely digitizing an entire topo-sheet is 3 to 4 times faster with AutoCad MAP. But once you have some vector data, editing it further in AutoCad Map is an tedious process and i would recommend sticking to ArcGIS Desktop.

I would suggest reprojecting the .shp file using ogr2ogr. In this way you can avoid any problems with Autodesk's reprojection engine crashing. ogr2ogr -f "ESRI Shapefile" original.shp wgs84.shp -s_srs EPSG:27700 -t_srs EPSG:4326 where in this case we are re-projecting 'original.shp' from OSGB36 British National Grid to Longitude / Lattitude WGS84 and ...

To lighten some happy mood, I suggest you to use FME Server. Since FME is a very powerful engine, your conversion should be done without much complexion. Figuratively, numerous format can be selected here. But bear in mind that the files should be organized. Otherwise, it would means nothing. Click here: ...

If you have ArcGIS available (I'm using 9.3.1), the easiest way will be to: Convert\export your shapefile into any file geodatabase and add it to your Arcgis Project; Label it using the attributes you need to show in CAD; Right-click the Layer Name in the content table and use the Convert labels to annotations option. Make sure you save the annotations in ...

ArcGIS - you can view 3D AutoCAD files in ArcGIS without having to convert. You can also easily convert DXF or DWG into ESRI Geodatabase (native spatial data format) if you which to furter manipulate/analyze the various features contained in the model. A word of caution; whereas ArcGIS is good at displaying 3D AutoCAD drawings you will not be able to edit ...
