Hi,
 
I am working on cabinet design & if I copy some items (item graphic) & pasting somewhere else it is showing so many constraing bars, now if I want to dele all the constraint bars at a time, so how to do that or how I can remove that constraint bars.
Please find attached snap shot for reference & provide the solution
 
 

To delete the constraints go to your Parametric tab and look on the Manage panel for the Delete Constraints command.To disable constraints altogether look on the task bar at the bottom left hand corner of your screen and click on the first icon.  I believe that it is labeled Infer Constraints.  It is either enabled or disabled.
