In the 2015.f version, checking bars is an analysis option, and so, users can analyse the structure with or without checking bars. In previous versions, when the job was analysed, bars were checked and users did not have the option to analyse to simply obtain forces.
As of the 2015.f version, results which depend on bars having been checked will not be available if the option “Check bars” has not been activated. By including this option, the use of the program has been optimised especially in the early design stages of the structure where users do not wish to check sections but rather know how the structure behaves and how the forces are distributed.
