![]() So, I think I should continue face reduction and wrapping to merge many of the faces and get a lighter part. I assume it will work as a normal solid part from now on, except that there are thousands of small surfaces. spicetraders at 17:05 Add a comment 3 Answers Sorted by: 1 If you can handle a single intermediate step, you may find that OpenSCAD will perform as required. Meshlab includes special filter for filling holes in 3D meshes. off so not familiar on how well MeshLab handles them. We can easily repair surfaces of mesh in Meshlab program. The size increased to ~20 MB again as soliWorks part but I could open it in ANSYS design modeler (took more than one hour to recognize all small faces) and then I could meshed it in ANSYS Mechanical. Look at MeshLab it imports and exports both. Anyway, I saved it as a *.stl again, imported into SolidWorks and converted it as solid body as *.sldprt. BackPageLocals is the new and improved version of the classic. I don't know why but I was expecting the convert button is active in SpaceClaim so I can directly convert it to Solid body but it was not. Combination of wrapping, face reduction and shrinking finally reduced to size to about 3 MB as stl file. The tools within the Facet ribbon are quite handy. I am still working on it but so far I am sure SpaceClaim CAN do the work. I was going to use ANSYS finally and the embedded SpaceClaim was quite useful. Initially SolidWorks was useless, and also FreeCAD didn't help, it crashed. A small object of about 1" bounding box, more than 90 MB and 2 mil faces saved as stl coming from a scanner. MeshLab is among the most promising programs for that. Off by default because it is very useful only in particular situations like when you have perfectly flat areas finely tessellated.I faced the same situation. Chances are that your 3D application already has this. Meshlab malformed file upon stl import Issue 1281 cnr-isti-vclab/meshlab GitHub cnr-isti-vclab / meshlab Public Notifications Fork 725 Star 3. Fortunately there's a solution known as polygon reduction (also known as mesh decimation). Some tools like ZBrush can quickly create a high polycount, so it's easy to run into this limit. Like the quality threshold it affects the accuracy/complexity ratio. The maximum amount of polygons our printers can work with is 1 million. It can greatly improve the quality of the shape of the final triangles on perfectly planar portions of the mesh. It’s on by default.Īdd additional simplification constraints that try to preserve the current shape of the triangles. If disabled, the edges are collapsed onto one of the two vertices and the vertices of the final mesh are a subset of the original mesh. When collapsing an edge the chosen vertex position minimizes the current estimated error. Optimal position of simplified vertices: Yes. As long as your mesh is closed and manifold (it looks like yours is - if it isn't, you can probably fix it using a combination of filters like Cleaning and Repairing -> Repair non Manifold edges by removing faces and Remeshing, Simplification and Reconstruction -> Close Holes), this is something you will need to configure in your. The value is in the range : 0 accept any kind of face (no penalties), 0.5 penalize faces with quality Normals, Curvature and Orientation > Re-Orient all faces coherently (note that this will only work for manifold objects). Meshlab does not have the concept of a 'solid' or 'hollow' mesh. To approximate accurately the original shape only with well shaped triangles you require a higher number of faces with respect to allowing more freedom in the final triangle shape. ![]() Quality threshold affects the simplification penalizing bad shaped faces. ![]() MeshLab can't create new objects but it has various editing tools, especially for merging. Go to File > Import Mesh and select your model. Keep this below 1 million.Įnter a value between 0 and 1 here the higher the value the harder MeshLab tries to stick to your original model's shape. How to edit and repair STL files in MeshLab. History edit Weirton Steel Corporation was an integrated steel mill founded in 1909 by Ernest T. With Meshlab, you can process raw data that is produced by 3D digitization tools and you can prepare your 3D models for 3D printing. It provides a set of tools for editing, cleaning, healing, inspecting, rendering, texturing and converting meshes. Target number of faces - Self explanatory. Meshlab is a software that deals with triangular meshes. ![]()
