Export to DXF

After a sounding has been completed, it is possible to export both the background map (vector maps only),
and the regularly spaced soundings (matrix) to an AutoCAD DXF file for further processing.

AutoCAD DXF files can be opened using AutoCAD, or you can use other CAD software such as QCad, or import the data in other GIS packages.

After you have created a matrix of your sounding, sections or map, you should have something like this:

Sample matrix file

Starting the DXF export tool

The DXF exporting tool can be started by selecting the "Export" => "Export DXF Data" from the "File" menu. The following window should appear:

Export to CAD toolbox

Select items

First, you have to select the items you wish to export as DXF features. The following Hydromagic objects can be exported to DXF:

Just enable the checkbox in front of the objects you want to include in the final DXF file.
To reset the selection, click the "Select None..." button, to select all objects, click "Select All...".

Output options

File name

Next, you have to select a file name for the DXF file. Click the "Browse..." button to select a file.
If a file already exists, you will be prompted. If no extension has been supplied, .dxf will be appended.


It is possible to write the DXF data using another map projection then the one which is used in your current project.
To do so, click the "Select..." button to choose the map projection for the output file.

Generate WKT projection file

When this option has been selected, an ESRI WKT compatible projection file will be written,
allowing other software to set the correct map projection for the DXF file.

Starting the export process

When all parameters are setup correctly, click "OK" to start the export. A progress indicator will appear at the bottom at the screen, and the window will close after a couple of seconds.
You can now open the DXF file in most CAD programs, it is also possible to use the generated DXF file as a background map in Hydromagic.

Opened in a CAD editor, the result will be (depending on your settings):
