Hmm OK then it's probably easier to fix in in vector program before copy/past ein MOI.

Just as an idea is there maybe scrip which could "merge/snap" points with tolerance ? Like we have merge/weld points in LW (and many other 3D software) which has value input field so when i set merge points 1mm it welds/merges all points within that distance. System like that could fix it in MOI also - right ?

Thanks for examples Michael
