2. Select the objects, data and properties to export
- You can choose all the objects, a selection subset or a specific layer.
- In addition, also data fields and other properties can be selected for creating output data fields: layer, color, text, area …
3. Choose the destination SHP
- Define the output folder, filename and select ESRI Shapefile (SHP) as your output format.
4. Shapefile parameters
- Geometry type: if you want to restrict geometry type, select one, otherwise leave automatic selected, multiple output files will be created if there are different geometry types.
- Encoding: default options is recommended, but you can change it if you need some other specific charset.
5. Coordinate Reference System transformation
- If there is already defined a coordinate reference system in the drawing, it will be automatically selected.
- It can be converted to a different coordinate system, allowing the selection of the transformation that best fits the area in order to preserve maximum accuracy.

6. Export
- Click Finish to begin the export process. Spatial Manager for GstarCAD will create the corresponding .shp, .shx, .prj, and .dbf files in your chosen location.
For more information and other supported formats, you can review the Export spatial data feature page.
Is there alternative for the inverse process, import Shapefile to GstarCAD?
Yes, it can be done using SPMIMPORT command, review Import spatial data feature page.
What are the Shapefile companion files?
When exporting to Shapefile format, it is important to understand that a SHP file is part of a group of related files. Spatial Manager automatically generates the required companion files during the export process, ensuring compatibility with standard GIS software:
- .shp — stores the geometry (points, lines, or polygons)
- .dbf — attribute data in tabular format
- .prj — stores the coordinate system information
- .shx — index file for the geometry
- .cpg — character encoding for the DBF file
- .sbn / .sbx — spatial indexes used by some GIS applications, not created by Spatial Manager
Are there alternatives for other format exports?
Yes, Spatial Manager for GstarCAD supports various other formats for exporting spatial data, including:
- GeoJSON
- KML/KMZ
- GML
- CSV
- And more…
