Remove dashed lines from Simulink diagram

Hello,

Sometimes, after editing a simulink diagram many red dashed lines remain on diagram. Is it possible to remove all them at once ? Thanks.

delete_line(find_system(your_model, 'FindAll', 'on', 'Type', 'line', 'Connected', 'off'))

Thanks. Does exist a shortcut for this command somewhere in Simulink options, e.g. "Refresh Diagram" or something like this ?

Not that I am aware. This code will find and delete all unconnected lines, which is something that should be done carefully. If you want to make it easy to do repeatedly, you could consider making it the ClickFcn of an annotation on your diagram.
