GML

Export GML

Create Geography Markup Language output for systems that require XML-based geospatial exchange.

Overview

GML export writes CAD drawing data to .gml output.

Use the common vector export workflow and include the attributes required by the receiving system.

Common vector workflow

This format uses the common export workflow: selection, object types, attributes, export options, and output path.

Steps

Run EXPORTGEO_SP or click Spatial Data > Export.
Select GML in the Select Export Format window.
Complete the format-specific options window.
Choose the output path when prompted.
Wait for the progress window to finish.
Open the output in the target application and review the exported data.

Best Practices

Confirm the drawing CRS before export.
Use layer-based selection when layers already represent logical GIS layers.
Keep only the required object types enabled.
Use the curve approximation step carefully for curved geometry.
Review the exported file in the receiving application before delivery.
