i am trying WeldVertices command…:
Post your model and I’ll run it through the debugger and see if I can figure out what’s going on.
OK. Thanks for the file and I can replicate the problem. I’ll dig into this on Monday and let you know what I find.
This will be fixed in the 6.6 service release.
In V6, the command was not replacing the object in the document if it failed the validity test. In your case the object was invalid (one face had two different vertexes with the same 3d location) prior to running the command so it would have never succeeded.
This fix removes the validity requirement and notifies the user when the output is not valid.
In the meantime, you can run CullDegenerateMeshFaces to get rid of the problem prior to running WeldVertices.
Great! Thank you very much.
