Hello, long time no blend. lol
I recently took it back up again and found myself with a question I needed answered a couple years ago.
This is a thruster section for a modular multi-purpose drone (if that matters …lol)
I made some changes to one side then split off the other, deleted it and mirrored the changed half over using shift-d. It has no complete center line so I had to delete a few overlapping verts to get it to the image you see.
My question …Is there a possible way to weld all the verts at once or can it only be done one face at a time?
