Hi Anistasia,

I believe that the "SCIRun::NewField::JoinFields" module does what you want -- just pass it a single field and select the "Merge duplicate nodes" checkbox (it's actually already selected by default) and then specify the tolerance that you want to use in the text entry field.

Hello All,

I am trying to save an isosurface extracted in SCIRun as a triangulated surface. I am doing this using the module WriteField and choosing the TriSurf option. This produces .pts and .fac files. The problem is that there are some duplicate entries in the .pts file and there are triangle definitions that actually join the vertices with the same coordinates.

I tried the decimating module, the fairmesh module and even the refine mesh module just to see what happens. None of them fix the duplicate problem.

Would someone please make a suggestion?
