In DF 2019 we have new feature call “Checking the Unconnected Length”.

But this feature is not in the What’s New online help, since it is execute by simple macro syntax.

  1. Let open the DF 2019 online help and open the page:

Home > Guide to Applications > Checking Design Data > Checking the Unconnected Length


  • To find macro syntax click link “unclength-report”.


  • Copy & Paste the “( unclength-report )” to register it for one of User Command.


  • Add it under Quick Access Tool bar

  • Execute this command without select any of un-connected net will get this message.
