Hello, I extend my best wishes for the new year 2017. I get something strange. On a part of my PCB I get an invisible wire Which is seen in photography mode. see below : ![enter image description here][1] and : ![enter image description here][2] I try to remove it by selecting it or redraw the wire above it. Nothing works. I also able to catch each extremity or corner to extend this wire. You have always access to my project Sonde Picine. rds liosab38 [1]: /editor/20170106/586f571224083.png [2]: /editor/20170106/586f5763d3336.png
