Export your model in *.glb format, selecting 'Apply modifiers' but not the 'Compress' option.

If decimation creates UV holes, try Meshlab decimation first.

Decimate as shown below, aiming for under 40,000 faces per mesh.

Import your 3D file (GLB, GLTF, DAE, ABC, USD, BVH, PLY, STL, FBX, OBJ and X3D only).

For optimal results, we recommend using both MeshLab and Blender, with MeshLab being particularly useful for very high-definition static models.

Avoid creating holes in the model's texture by regularly checking the rendering after each decimation.

Decimate Your 3D Model with MeshLab and/or Blenderĭecimating a 3D model reduces its vertices, potentially causing a loss of definition. This conversion prepares your 3D model for the next step. Import your 3D model into the interface and export it in. Convert Non-Annotated 3D Models with CAD AssistantĬAD Assistant is a free 3D CAD converter for personal and commercial use. Otherwise, use our recommended method involving CAD Assistant, Meshlab, Blender, and Gimp: 1. Begin by reducing the model's vertices directly in the design software if possible.

Reducing the Size of Industrial 3D Modelsįollow our step-by-step guide to create a lighter CAD 3D model for augmented reality display using an AR Code. These models often use dedicated file formats. CAD models require high-definition for production and are created using dedicated 3D CAD software like 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. Understanding Industrial 3D CAD ModelsĬomputer-Aided Design (CAD) refers to 3D modeling for parts and assemblies in the Industry & Manufacturing sector. Our method supports various 3D CAD file formats, including 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. For high-definition static CAD models, we offer an alternative approach to achieve optimal results for your final AR render. We previously published tutorial on reducing 3D model sizes with Blender, an effective method for most 3D models, including animated ones. Tutorials | Monday 20th of March 2023 03:09:28 PM |
