SimLab OBJ Exporter for SolidWorks: Full Workflow Guide Exporting native SolidWorks files to OBJ format is essential for rendering, animation, and game development. The SimLab OBJ Exporter plugin provides a direct, efficient way to convert your parametric CAD data into high-quality polygons. This guide covers the complete workflow from installation to final export. Why Use SimLab OBJ Exporter?
SolidWorks does not natively export to the OBJ format. SimLab bridges this gap by converting precise CAD geometry into optimized polygon meshes while preserving colors, appearances, and assembly structures. This allows you to bring your engineering models directly into software like Blender, Maya, Unreal Engine, or Unity. Step 1: Installation and Setup
Download the Installer: Visit the SimLab Soft website and download the OBJ Exporter plugin compatible with your version of SolidWorks.
Run the Setup: Close SolidWorks and run the installer. Follow the on-screen prompts to complete the installation.
Activate the Plugin: Open SolidWorks. Go to Tools > Add-ins, locate SimLab OBJ Exporter, and check the boxes for both “Active Add-ins” and “Start Up”.
License Activation: Click on the new SimLab menu tab in SolidWorks. Select Register to enter your trial or purchased license key. Step 2: Preparing Your SolidWorks Model
Before exporting, prepare your model to ensure a clean file transfer and optimal performance in your target application.
Suppress Unnecessary Features: Hide or suppress internal components, fasteners, and complex geometry (like small fillets or threads) that will not be visible in your final render. This reduces the final file size.
Check Material Assignments: Ensure all materials and colors are applied correctly at the part or face level. SimLab uses these assignments to generate your OBJ material (.mtl) file.
Resolve Components: Make sure all assembly components are fully resolved and not lightweight. Step 3: Configuring Export Settings
Click on the SimLab tab in the SolidWorks top menu and select Export. Before saving, click on Settings to configure your mesh output: Mesh Quality (Tessellation) This setting controls the density of the polygon mesh.
Fine/High: Best for close-up renderings. It creates smooth curves but results in a larger file size.
Coarse/Low: Best for real-time game engines or large environments where performance is critical. Coordinate System
SolidWorks uses a Y-up or Z-up orientation depending on your template.
Check the coordinate system of your target software (e.g., Blender is Z-up, Maya is Y-up).
Use the SimLab settings to flip the axes during export if necessary to avoid your model importing sideways. Step 4: Exporting the File
With your model open, go to the SimLab tab and click Export. Choose your destination folder and name your file.
Select OBJ Files (*.obj) from the save file type dropdown menu. Click Save.
SimLab will process the geometry and generate two distinct files in your destination folder:
.obj file: Contains the 3D coordinate and polygon mesh data.
.mtl file: Contains the material definitions, colors, and mapping info. Always keep these two files together. Step 5: Importing into Target Applications
When importing your newly created OBJ into your downstream software, keep these tips in mind:
Keep Files Together: Ensure the .obj and .mtl files remain in the same folder so the importer can automatically reapply your colors and textures.
Scale Factor: CAD data is scale-accurate (e.g., millimeters), while polygonal software often defaults to meters or arbitrary units. You may need to scale your model up or down by a factor of 10, 100, or 1000 upon import.
By following this workflow, you can reliably transition your rigid engineering designs into versatile, visually stunning assets ready for any creative pipeline. To help tailor this guide, let me know: Which version of SolidWorks you are using?
What is your target downstream software (e.g., Blender, Unreal Engine, Keyshot)?
Are you experiencing any specific errors or material loss during export?
