Purging or Clearing Existing Constraints in an Allegro Board File

cstocci52

Folks,

Is there an easy and simple way to purge all of the existing constraints in an existing Allegro layout?  I get boards from previous bureaus that have a ton of constraints and it takes me a fair amount of time to clear them out before I can do my thing.  I am running spb 17.40, but I get Allegro versions back to 16.3 to deal with many times.

Thanks!

    The easiest way I have found to remove all the constraints in a design is to:

    1. First open a new board file, then open Constraint Manager & export it's constraints using the Generic cross-section

    2. Then open the existing board file, then open Constraint Manager & import the last saved constraints using the Override Import Mode
