I have the same problem, over and over again… I am using Millipede and Cocoon Marching Cubes.
I tried _AlignMeshVertices and _UnifyMeshNormals, as well es Combine&Clean and Mwesh WeldVertices. MeshRepair doesnt have any effect.
Actually I managed to have some results with AlignVertices Component, but it take quite long and assume for bigger meshes the render time scales linearly or worse.
I would appreciate swift guesses over solutions - need a fix urgently.
Also any suggestions on how to create faster mesh (marching cubes or else from line geometry) that have more equally sized faces would be as well highly appreciated.
I replied to this post in the old forum, but as noone seems to be active, i recreated the request here. (http://www.grasshopper3d.com/forum/topics/1-wbprocessingexception-two-consecutive-edges?page=1&commentId=2985220%3AComment%3A1911010&x=1#2985220Comment1911010)
01 without AlignVertices
02 with AlignVertices
03 the wanted result after smoothing
