Merges the UVs shared
by the edges that you attach. If turned off, the UVs are not merged
and can be manipulated and edited independent of each other.
Threshold
Any vertices further
apart than this distance will not be attached. Set this value carefully.
If it’s too small, no vertices will attach. If it’s too large, the
operation may attach vertices that you do not want attached.
Keep Originals
Controls whether Maya
keeps the original surfaces you are attaching.
