Hi Toha, to remove an edge you would need the 2 surfaces on either side to be just one larger surface instead. That can be difficult to do after you've done booleans and such to an object. It's easier to do it earlier on when the surfaces are initially constructed. At that time you would want to focus on the curve structure that you used to construct the surface and make sure you don't have multiple segments in the curve.

Why do you want to remove the edge?
