xcsg - xml based constructive solid geometry
xcsg is both a file format and an application. For the file format definition, please see the xcsg wiki for detailed information.
The xcsg application
The xcsg application takes an input .xcsg file, compiles its data into a solid model, and exports it to common surface mesh file formats, including STL. The application uses the Carve library for boolean operations.
$ xcsg --help
xcsg command line options & arguments (v1.5-00):
-h [ --help ] Show this help message.
-v [ --version ] Show program version (numeric part).
--amf AMF output format (Additive Manufacturing Format)
--csg CSG output format (OpenSCAD)

--svg SVG output format (Scalar Vector Graphics - 2D only)
--stl STL output format (STereoLitography)
--astl STL output format (STereoLitography) - ASCII
--obj OBJ output format (Wavefront format)
--off OFF output format (Geomview Object File Format)
--export_dir arg Export output files to directory
--max_bool arg Max number of booleans allowed
--sec_tol arg Secant tolerance when importing OpenSCAD csg (0.05)

<xcsg-file> path to input .xcsg file (required)
example
To compute the difference between a cube and a sphere and store the result as STL
$ xcsg --stl difference3d.xcsg
The file difference3d.xcsg:
<?xml version="1.0" encoding="utf-8"?>
<xcsg version="1.0">
<difference3d>
<cube size="50" center="true"/>
<sphere r="33"/>
</difference3d>
</xcsg>The resulting STL becomes:
