Rebuild Surface help

Is there any way to rebuild the edges of the this surface so that it joins the edges together to make a 4 sided surface. I didn’t build this surface and from some reason 2 of the edges are split, and I would like to remove these split edges. I tried the rebuild edge command but that didn’t help.

Hi Dennis -MergeAllEdges should help. But, DupBorder, SimplifyCrv on the result, then PlanarSrf on the result will be simpler still.


Thanks the DupBorder, simplifyCrv, PlanarSrf worked well.
