"""
Alternative to _RemoveAllNakedMicroEdges, this script will remove all micro-edges,
both naked and interior, with no limiation of that the edges
"fold or loop back on themselves and have no matching edge to which they can be joined"
as stated in https://docs.mcneel.com/rhino/7/help/en-us/index.htm#commands/removeallnakedmicroedges.htm
Both naked and interior micro-BrepEdges, as defined by the MaxEdgeLengthToRemove
option, will be removed along with the relative BrepTrims.
For each edge removed, both end vertices are replaced with a single vertex at
the average location.
If this script fails, do the following and rerun the after each step until success:
1. _RemoveAllNakedMicroEdges on the target breps then this script.
2. _MergeAllEdges on the target breps then this script.
3. _Extract faces with micro-edges.
4. _MergeAllEdges on the extracted faces.
Send any questions, comments, or script development service needs to
@spb on the McNeel Forums ( https://discourse.mcneel.com/ ).
