Once you have generated some meshes, you can export them in various plain text file formats including STL, PLY, OBJ, GDML, and DXF. Choose the file format that best suits your use. STl, PLY and OBJ files are most commonly used for 3D printing. DXF may be more suited to CAD applications. Only contours that have meshes are made available in this window for export. Choose the meshes you want to save, along with your target file format, and click on Export.
Depending on the file format, colour information is also included where possible. You can also choose whether or not to save your meshes into one file, or save each mesh into its own file.
