Blender is generally the best choice for most 3D models, but MeshLab can be useful for very high-definition static models that may experience decimation issues when using Blender. To avoid this, it is important to regularly check the rendering of the model after each decimation to ensure that the model maintains its desired appearance.įor the best results, we recommend using both MeshLab and Blender.
If the decimation is too aggressive, some vertices may lose their texture information, causing the model to appear to have holes.
2 - Decimate your 3D model with MeshLab and/or Blenderĭecimating a 3D model will reduce its number of vertices, which can result in a loss of definition, particularly on curved parts of the model. This simple conversion step will prepare your 3D model for the next step. Import your 3D model into the interface, then export it in. If you can't have access to the software and to go further please refer to the method below with CAD Assistant, Meshlab, Blender and Gimp: 1 - STP (STEP), IGS (IGES), LOG, OFF, 3DM, VRML, WRL, MSH, XBF, BREP files: Convert your 3D model with CAD Assistant (NON-animated model only)ĬAD Assistant software is a free 3D CAD converter for personal and commercial use. Reduce the size of an industrial 3D modelīy using the method below, you can get a lighter CAD 3D model for augmented reality display via an AR Code.Īs a first step, if you have access to the software used to design your model, you can reduce its number of vertices directly in it. The file formats used are also dedicated. What is an industrial 3D CAD model?ĬAD stands for Computer Aided Design, it is mainly used to name the 3D modeling done for parts and assemblies in Industry & Manufacturing.īecause they need high definition to enter production, they are modeled on dedicated 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. This method supports the following 3D CAD file formats: 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. But for some static CAD models that have very high definition, there is a way to get a better result for your final AR render. We previously published a tutorial on reducing the size of any 3D model with Blender, a method suitable for most 3D models including animated ones.
