Export / Triangle text file

Triangle text file command creates a text file from surface model triangles. The triangles can be written into simple text files for points and edges, into exchange format text files, such as LandXML, or into survey application-specific text files. Supported triangle text file formats are 4ce DOT, GMS, InfraModel 4.0, ICC, Moss triangulation, LandXML 1.0/1.2, Point & edges text file, SMS / WMS and WorldToolKit NFF.

To create a text file from surface model triangles

1. Select Triangle text file command from the File / Export pulldown menu.

The Export Triangle Text File dialog opens:


2. Select a Surface for which to export the triangles.

3. Select a Format for the output file.

4. If required by the format, define additional settings.

5. Click OK.

This opens another Export triangle text file dialog, a standard dialog for saving files. If triangle points and edges are saved into separate files, the dialog opens for a second time after saving the first file.
