SolidWorks Configurations to STL Export Macro

Overview

This SolidWorks VBA macro exports all configurations of the active part or assembly to individual STL files.
It is designed for users who manage multiple configurations (e.g., via Design Tables) and want a quick, automated way to generate STL files for each one.

Key features:

• Exports every configuration as an STL file
• Filenames are based on configuration names (invalid characters replaced)
• Creates an STL_Exports folder next to your model automatically
• Uses your last-set STL export settings (resolution, units, binary/ASCII)
• Supports both parts and assemblies (assemblies exported as one STL file)

---

Requirements

• SolidWorks (any recent version that supports VBA macros)
• A saved SolidWorks part (.sldprt) or assembly (.sldasm) file with multiple configurations
• STL export settings already configured in SolidWorks

---

Installation

1. Download the config2stl.swp macro file from this repository.
2. Open SolidWorks and your part/assembly file.
3. Go to Tools → Macro → Run...
4. Select the downloaded config2stl.swp file and click Open.

---

Usage

1. Before running the macro, set your STL export options:
   • File → Save As → STL → Options...
   • Configure resolution, units, and binary/ASCII settings
   • Click OK and cancel the Save As dialog (settings will be saved)
2. Run the macro.
3. The macro will:
   • Loop through all configurations
   • Export each as an STL file
   • Place them in a subfolder STL_Exports in the same location as your model

---

Customization

• Output folder name: Change the OUTPUT_SUBFOLDER constant in the macro code.
• Assembly export mode: Macro currently exports assemblies as a single STL; this can be modified if needed.
• Filename sanitization: The macro replaces invalid filename characters with underscores.

Example

If your file is located at:

C:\Projects\MyPart.SLDPRT

After running the macro, you’ll get:

C:\Projects\STL_Exports\
    Config1.stl
    Config2.stl
    Config3.stl
