My most recent extension is now live in the warehouse. The plugin welds edges into curves but unlike other weld plugins it doesn’t just weld the selected edges but searches for edges to weld. If there is a selection the search is limited to it, otherwise all edges in the current drawing context that can be welded are welded. It also automatically welds the geometry created by Follow Me, meaning you can use Follow Me multiple times without having the surfaces segmented.
The plugin costs 10 USD and has a 14 day trial. Enjoy!
