Description
This macro provides a convenient way to export selected FreeCAD objects to multiple file formats at once. Instead of exporting to each format individually, you can select all desired formats in a single dialog and export them simultaneously.
Supported Export Formats:
- STL - Stereolithography (common for 3D printing)
- STEP - Standard for Exchange of Product Data (CAD interchange)
- 3MF - 3D Manufacturing Format (modern 3D printing format)
- OBJ - Wavefront OBJ (3D graphics and game engines)
- IGES - Initial Graphics Exchange Specification (legacy CAD format)
- BREP - OpenCASCADE native format (preserves exact geometry)
- PLY - Polygon File Format (3D scanning and printing)
- AMF - Additive Manufacturing Format (XML-based 3D printing)
Features:
- Export to multiple formats in a single operation.
- User-friendly dialog for format selection.
- Configurable output directory and base filename.
- Mesh tolerance settings for STL/OBJ/PLY/3MF/AMF exports.
- Preview of files to be created.
- Quick select buttons: "Select All", "Select None", "Reset Defaults".
- Default formats: STL, STEP, and 3MF are pre-selected.
Usage
- Select one or more objects in the 3D view that you want to export.
- Run the macro from Macro → Macros → MultiExport → Execute.
- In the dialog:
- Review the selected objects in the "Objects to Export" section.
- Check the formats you want to export to (STL, STEP, 3MF are selected by default).
- Choose an output directory using the "Browse..." button.
- Enter a base filename (the format extension will be appended automatically).
- Optionally adjust mesh tolerance settings for mesh-based formats.
- Click "Export" to create the files.
Requirements
- FreeCAD 0.21 or later.
- Objects with solid shapes (Part or PartDesign bodies).
Installation
- Install via the FreeCAD Addon manager or manually from the freecad-macro-3d-print-multi-export repo on GitHub.
