Meshlab boolean software#
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.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. Tutorials | Wednesday 22nd of June 2022 03:09:28 PM |
Meshlab boolean how to#
stl version you can export a mesh version.VIDEO TUTORIAL: How to compress / reduce the size of an industrial 3D CAD model with MeshLab and Blender? If you know the parameters, rebuilding that structure from scratch + boolean is a 10min job over there. Now do a BooleanUnion in one go (not this will need some time or even overrun your systems resources).Īnother option might be running EDIT/MakeSolid (with a high MeshDensity and SolidAccuracy) on your combined source mesh.Īgain: Any reasons why you do not do the Boolean still being in CAD? If Gibbon doesn't have such a feature switch to another CAD package (maybe Fusion360 or Rhino). The next Boolean might intersect this density "transition" and might get problems on its remesh.Ĭombine all vertical layers to one and all horizontal to one object. Theres a harsh density difference between the remeshed and the non remeshed region now. Let's say you did one Boolean with AutoReduce disabled. Seems the self intersections are caused in the different Boolean steps. Not knowing your current source meshes (the straight tubes in the last version you posted are still made of only a few triangles) and your boolean strategy: Hint: Disable AutoReduceResult to avoid distortions on hard edges. Now EDIT/SeparateShells, activate a pair of objects and run BooleanUnion: So SelectAll and run SELECT/EditRemesh (for its settings refer to the image): So there are several intersections on a very same triangle:
The reason why BooleanUnion fails is the low triangle density on the straight tubes. Now if there's no change to go back to that source application and you fixed duplicate issue (be aware that this is a time costly process doing it for all those layers): The easiest way I know to get rid of duplicated faces is to use Meshlab and its RemoveDuplicateFaces tool (>Filters > CleaningAndRepairing). stl isn't an indexed format this results in duplicated, non manifold faces (that's the reason for those red lines in MM). Seems there were duplicates of the first, second and 20th layer exporting from the source application. Seems this object was done in some parametric CAD package? If so: Try to weld the layers there! It's much easier, faster and accurate doing such welding in a different representation (as BRep) than to weld meshes.
