Hi again. Got another issue. I have just tried converting my poly fuselage on my plane to sub-ds, and I'm getting an error that I cannot convert due to multiple duplicate edges.

I have a bunch according to the highlights when using the Merge Edge Tool, but using it causes adjacent edges to attach to where the tool was clicked. I've tried all 3 settings in the Merge Tool but they each give undesirable results.

Is there a way to get rid of the multiple edges without hurting the integrity of the mesh?
