Replicating Patterns

[ivla]

I'm not sure I understood your point.

First point is about those isolated vertices for welding.

Second is about choosing a place for the border of the pattern:

After first duplication (by Z) and welding there is no edges to delete - the border of pattern is an element of this pattern.


After second (by X) there will be an edge loops that does not match any pattern element so it can be easily selected for dissolving.


This pattern is worse because its border is partially match the pattern elements - so the selection an edges to delete after replication and welding is far more complicated.
