AutoCAD is a vector drafting software so it doesn't have attributes in the traditional GIS sense like ArcGIS or other GIS's do. Its attributes are meant for the vector (line) parameters such as colour, line thickness, etc. You can add CAD fields to your shapefile and populate those fields with attributes prior to exporting to CAD which will control the ...
If it is 3D DXF, follow the steps:
import the dxf in QGIS (DRAG & DROP or CTRL + V);
save as vectors (as the right mouse button);
add new field Z (integer);
Browser Panel to create a new database spatialite;
DBManager to import the shape in the newly created database;
run the update query;
step 3 - add new field Z
step 5 -DB Manager
@pigreco's answer should work.
But here a simpler solution without the spatialite process (step 1 to 2 are the same).
Load your .dxf and export (save as...) as shapefile (or spatialite / postgis).
On the new layer, use the Field Calculator (accessible from the main toolbar or from the attribute table).
Setup the new column (name and type, virtual or not ...
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.
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 ...
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.
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, paste it ...
I actually figured this out while I was typing my question. I decided to still submit the question, and supply an answer just in case it helps someone else.
You need to go into the Layer Properties, and Symbology tab of the CAD layer and change it from CAD unique entity values to Unique values, many fields.
This keeps the symbology the same, and then you ...
To align any number of objects, you can transform them into a block (see tutorial if necessary):
launch the _bloc command
give a random name (2)
click on a place near the objects to be georeferenced (6)
Select all your objects you need (4+3)
Click on allow exploding (8)
Click OK (9)
Next your can georeference your bloc with _align. when you're satisfied, ...
QGIS uses GDAL/OGR under the hood which supports dgn/dwg (read only) and dxf (read/write).
See OGR formats for a list of supported formats. Note: dwg support may be missing as it is not compiled into OGR by default. DGN support is only for DGN v7 files.
try FME , costs , but manages all your conversion problems
For me it has been the best spatial tool in my job, i do file type conversion, i reproject data with it, i do some spatial db stuff with it.
This is a loaded question. You can do a great deal more with map capable versions of AutoCAD than just drafting related activities. Really there are too many possible functions to discuss; especially in reference to the AutoCAD Civil 3D environment. In many cases, a client will have CAD drawings that serve as a starting point in a broader project, or from ...
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:
Qgis uses GDAL's ogr2ogr to export between formats and from www.gdal.org, "Polygon and MultiPolygon features are written as HATCH entities", so the hatches in AutoCAD should be expected. To generate closed polylines from the hatch objects use the AutoCAD command HATCHGENERATEBOUNDARY.
Additionally you could use the command OGR2OGR to export the shapefile ...
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 ...
I have an answer, thanks to the insightful comment by FelixIP. Felix suggested exploding the linework might fix this issue. I passed this suggestion to the client, who said the following in reply:
The original boundary was a closed shape which I have dropped (exploded) to individual line segments.
This change fixed the issue. The engineer noted that he ...
First, when you bring your DWG into ArcMap, there is no need to convert it to another file type, unless you are trying to edit the linework. You can view the file and change the way it looks without doing any conversion.
(If you do need to edit it, right-click on the Polyline layer in the DWG and choose "Data" and "Export Data." You can then export it ...
you should use the merge tool (or the append tool) to copy your points from one dataset to the other dataset. Launched from ArcGIS, the selection will be honored + this will reproject on the fly. Your points are probably moving because their projection was not defined. This can be done using the define tool. At the end, only one coordinate system is possible ...
Ubuntu 14.04, QGIS 2.8.1
The way I did this with your test file was to convert the DWG file to a DXF using (free) Teigha File Converter. Then I loaded the DXF into QGIS and tried to polygonize it (using 'Polygonize' from the Processing toolkit). In fact 'Polygonize' only partially converted the lines to polygons, there is a problem with the DXF.
So, it was ...
you can use the dxf interchange format for CAD to export your data. This conversion tool is available in ArcMap (Conversion toolbox/to cad/ export to cad, then choose dxf as output format).
from the other side, shapefiles can be imported in AutoCAD MAP 3D using insert > import panel > map import
Plain AutoCAD has no command to open or import the geospatial vector data format shapefile.
The geospatial vector data format shapefile consists of a collection of files (*.shp, *.shx, *.dbf and other).
Beware of confusion: AutoCAD uses *.shp files for custom symbols. These *.shp files are also called shapefiles but are not the same as the geospatial ...
In short, no, it doesn't appear that latest AutoCAD 2018 has a compatible plugin to use ArcGIS. According to Esri's ArcGIS for AutoCad and For AutoCAD 2013-2017
Installation recognizes the most recent version of AutoCAD 2016 and 2017, as well as previous version 2013-2015.
Important 2018 update
I'm not sure which update of QGIS 2.x and 3.x changed it, but as of 2018 November and probably earlier, geometry generator symbology styling does get exported with the native QGIS dxf exporter. Generated polygon geometries styled with outline only will be exported as polylines; albeit with many vertices still.
So all of the below is ...
You can also look into the AutoCAD university. Free one year edu license and all the tutorials you can stand.
That being said, I am on the other side of the fence and use GIS in Public Works. Engineerinfirms give us spatially correct surveys, plats, etc., and I add the tabular data that goes with it. Understanding the concept s of both are key. How they are ...
As a person with this background I can talk directly to that topic. What employers are often looking for is people that have production linework experience; or the ability to do solid and consistent data creation work. CAD is often a lot less subjective; whereas GIS with is background in Enviro/Planning arenas has less of a rigid expectation.CAD shops often ...
Older versions of CAD often would give you errors of drawing outside the limits. I found the LIMCHECK command would allow me to extend the limits of the drawing area. In newer versions of CAD though, this is not required.
update (early May 2017). GDAL supports DGN v8 from version 2.2.0. More info about the driver. Not tried this yet so can't vouch for completeness.
New OGR/vector drivers:
- DGNv8 driver: read-write support for DGN 8.0 format (using Teigha ODA libraries)
It might be a while before QGIS uses this, but could try installing it on a virtual machine or ...
