Weld Problem with attached mesh


I tried to weld this mesh with 180 degrees to get rid of multiple vertices, but Rhino does not weld the open edges. Also the WeldVertices command does not work.
Can someone look at the file and tell me what the issue is?

thanks Detlef

Hi Detlef,

i’ve exploded then joined again. Then used _AlignMeshVertices on all naked vertices with a tolerance of 0.05 and _Weld 180 worked.

Hi @detlef_mueller,

you can also use MatchMeshEdge to get vertices aligned on those open edges.
