Fixing free 1-d's line mesh

I am wondering how I can fix free 1-d mesh made using line mesh. I imported a sketch from solidworks using a iges file and was able to use the line mesh to create the mesh but their are a few spots that have free 1-d's but I am not sure how to fix them. I have checked the sketch to make sure that the lines are connected before making the mesh and am able to find the free ends using the check elements but have not been able to figure out how to fix them.
