Hello.  I have just come back to SolidWorks after using Onshape for several years.  So far, I am not able to create and edit sketches efficiently.  My default settings have this terrible behavior where coincident endpoints in sketches get this kind of implicit, invisible coincident constraint.  Vertices are merged together and I can't get them apart.  There is no constraint to delete.  I can turn on the "Detach Segment On Drag" setting, but this takes too much time and I usually don't want to detach the segment, just remove one coincident constraint.  How can I change my settings so that all the coincident constraints are visible so I can selectively delete them?  Thanks
