2014年3月21日 · You might want non-manifold geometry in some kind abstract model (as non-manifold geometry cannot exist in the real world), or as an approximation of a very thin object (e.g. paper, leaves, etc.) Common causes of non-manifold geometry: Disconnected vertices and edges: Internal faces: Areas with no thickness: Fixing non-manifold geometry:

2020年8月18日 · I'm trying to understand Blender constructs and manifold vs non-manifold geometry. I do a lot of modeling for 3D printing, so really need to get this right. I've looked at a number of tutorials on YouTube, and Googled the subject extensively, but still cannot find anyone/anywhere that explains the basics.

2019年11月25日 · Non-manifold geometry is geometry where an edge is shared by more than 2 faces: This is what you should be looking for. It's easy to find using Select -> Select All by Trait -> Non Manifold . Once you find it you can fix it by deleting some unnecessary faces, or separating the edges. You could use Edge split for that:

2022年11月21日 · I'm trying to mesh this model via tetgen, but tetgen says the geometry is non manifold. Blender does say so too. The model is created by a couple of extrude nodes in geometry nodes. I've tried the brute force method of using the clean up which just merges the faces and hence closes everything up. This you can see in the second picture.

2021年4月18日 · I've tried quite a few guides on non-manifold geometry and it seems like my entire model is derped both in terms of vertices and edges, faces are okay apparently but I don't understand what I did wrong, I just extruded and merged vertices by edges to make essentially all of it, and even if I had extruded extra edges and forgot to undo them I ...

2018年12月3日 · I was able to correct the non-manifold edges by making a new face at the 4 internal vertices that made up the left and right side of the part of the design with the protrusions. However I still have 4 intersecting faces, 6 non-flat faces, and 2 thin faces.

2023年2月27日 · Apparently you have interior faces which are non-manifold. Read more about Non-Manifold geometry here. Remove those faces. Then you have this problematic vertex. It is correctly part of one face but not included in the other face. Remove it by selecting the vertex and pressing X > Dissolve Vertex. Then you have this funny interior face here.

2024年4月12日 · An object has a non-manifold edge where the edge is connected with more or less than two faces. A vertex that is not a face corner is either part of a non-manifold edge or it is a loose vertex and can either be selected in Blender as non-manifold or loose geometry.

2016年12月12日 · So to boolean-cut I'm stuck in using 3DSmax where there is the « Boolean » tool, which accept non-manifold geometry (edit: but just cut, it doesn't create new faces). It's a pain to switch between 2 3D softwares, and I would like to continue using Blender. Is there a way in blender to cut non-manifold geometry?

2015年12月26日 · For me, the usual cause for non-manifold surface due to boundaries is disconnected or doubled edges/vertices. Inspect the edge to see if there is something underneath or if you have a degenerate (0-area) hole in the mesh (e.g. 3 vertices in a line creating 3 edges resembling a flat triangle instead of the two valid edges etc.
