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

  1. Select one or more objects in the 3D view that you want to export.
  2. Run the macro from Macro → Macros → MultiExport → Execute.
  3. 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.
  4. Click "Export" to create the files.

Requirements

  • FreeCAD 0.21 or later.
  • Objects with solid shapes (Part or PartDesign bodies).

Installation

  1. Download the macro file: MultiExport.FCMacro.
  2. Copy the file to your FreeCAD macro directory:
    • macOS: ~/Library/Application Support/FreeCAD/Macro/
    • Linux: ~/.local/share/FreeCAD/Macro/
    • Windows: %APPDATA%/FreeCAD/Macro/
  3. Optionally, download the toolbar icon and place it in the same directory.
