Hello, Why taper makes my meshes wrong? Mesh1 - the original one - during the check reported as: This is a good mesh. Important things to consider with this mesh: Mesh has 5760 naked edges. Although this does not necessarily mean that the mesh is bad,* naked edges can cause problems if the ult…

Hello- please run RebuildMeshNormals and see if things improve. Not much more to sauggest without the original mesh and the inputs to Taper so we can reproduce the problem. You can send to tech@mcneel.com , with a link to this topic in your comments, or upload to Rhino - Upload to Support -Pascal

Hello, Rhino does not execute anything in response to " RebuildMeshNormals". I’ve just uploaded 2 files mentioned.

Hello- from what I can see, there is one file uploaded so far -Mesh2.3dm - it cleans up with RebuildMeshNormals, here, [image] but still has what I guess are incorrect self intersections called out. -Pascal

Hello, Just uploaded mesh1 again. Which version of Rhino are you using?

@amsarse sorry, something seems to dislike the Mesh1 file - the upload seems to have failed. Can you please try it again? -Pascal

Thank you - got the zipped version this time. @amsarse I can repeat the messing up of the mesh normals. I’ll send this to the developer for a look. However, RebuildMesh or RebuildMeshNormal should fix things apart from one normal, for some reason. Both give the same results, here. General informa…

It means that taper algorithm is faulty. Would the developer try to correct it?

My guess is, the reconstruction of the mesh and normals once the taper has occured is where it goes wrong, but I am just guessing. I have no idea what if anything can be done, but the idea would be to fix it, yes. -Passcal
