I’m trying to limit the number of vertexes to be considered in a remove doubles operation, but somethings not right.
In this picture I have a hard island of mesh that is separated from the main model. In edit mode I select the Hole edge in the main model, then the hard edge I want to attach to it. Vertex counts are the same in both selections and the vertexes aren’t offset by that much. Remove doubles is active.
When I increase the merge distance in the Remove Doubles options, the Hole Edge deselects, the merge does not happen where I expect it to and the merge distance has to be ramped up extremely for the separated vertexes to start welding.
Why does the Hole Selection toggle to deselect? (Bug? or My Process?)
I expected the selection to remain active and only the selected vertexes to be considered as weld points.
To get this to weld properly I have to toggle the Unselected checkbox on.
