VIDEO TUTORIAL: How to compress / reduce the size of an industrial 3D CAD model with MeshLab and Blender?
Tutorials | 01/08/2025 |
Discover how to elevate your AR Code experience using high-performance 3D models effectively. Previous discussions highlighted a tutorial on Blender for optimizing 3D model file sizes to improve rendering. This alternate method enhances augmented reality (AR) presentations when handling high-definition static CAD models.
AR Code supports an array of 3D CAD file formats, such as STL, OBJ, STP, IGS, OFF, GLTF, GLB, WRL, BREP, XBF, PLY, MSH, PNG, LOG, ES, 3DS, QOBJ, PTX, VMI, PTS, APTS, XYZ, PDB, TRI, ASC, TXT, X3D, X3DV, FBX, BRE, DAE, and E57.
Understanding Industrial 3D CAD Models for AR
In the industrial and manufacturing sectors, Computer-Aided Design (CAD) is crucial for creating high-definition 3D models of parts and assemblies. These models are developed using advanced 3D CAD software such as Fusion 360 Autodesk, Solidworks, CorelCAD, AutoCAD, Tinkercad, FreeCAD, SketchUp, Solid Edge, Bentley, LibreCAD, SOLVESPACE, BRL-CAD, QCAD, IRONCAD, PTC, CATIA, OpenSCAD, Rhino, and Siemens NX.
Optimizing Industrial 3D Models for AR
Explore our comprehensive guide on streamlining CAD 3D models for augmented reality using AR Codes. Begin by reducing model vertices in your design software. Our tried-and-true strategies make use of CAD Assistant, Meshlab, Blender, and Gimp for superior outcomes:
Step 1: Convert Non-Annotated Models with CAD Assistant
Take advantage of the free 3D CAD converter, CAD Assistant, which is ideal for personal and commercial use. Download it at https://www.opencascade.com/products/cad-assistant/.
Import your model and export it in .OBJ format, preparing for subsequent steps.
Step 2: Decimate Your 3D Model with MeshLab and Blender
Decimating reduces the vertices of a model but be careful of any potential texture defects. It is advisable to frequently check renders post-decimation. Using both MeshLab and Blender gives optimal results, with MeshLab being excellent for static model decimation. Explore more on reducing file size with our tutorial on how to compress or reduce the size of an industrial 3D CAD model with MeshLab and Blender.
Decimation with Blender: (https://www.blender.org/download/)
- Import your 3D file (compatible formats include GLB, GLTF, DAE, ABC, USD, BVH, PLY, STL, FBX, OBJ, and X3D)
- Decimate each mesh aiming for fewer than 40,000 faces. Use Meshlab if UV holes appear.
- Export in *.glb format, applying modifiers but skipping compression.
Decimation with MeshLab: (https://www.meshlab.net/#download)
- Import 3D formats like ES, 3DS, PLY, STL, OBJ, and more.
Choose based on texture presence:
- Textured: Apply 'Quadric Edge Collage Decimation' with texture.
- Without texture: Use 'Quadric Edge Collage Decimation'.
Ensure your model retains quality by setting the face count appropriately.
Export in *.obj format to include textures.
Step 3: Compress Textures with Gimp
If your model contains textures, follow these steps:
- Import model into Blender, exporting in .gltf + .bin + textures.
- Open texture files in GIMP.
- Scale images (recommend 1024x1024) for optimal compression: Image > Scale Image.
- Export as *.jpg with resolution 90 (or lower for enhanced compression): File > Export as.
- Edit the .gltf file to update texture formats (e.g., ".png" to ".jpg") and save.
Step 4: Convert Your Model to .GLB for AR Code Upload
Final conversion steps:
- Import .gltf model into Blender.
- Consider a Blender decimation post-MeshLab if needed, as detailed in Step 2.
- Export in *.glb format, applying modifiers without compression.
