With the Criteria - Effective Length command, ℓ/L major and minor values are set for the beams, columns and braces in the structure.

Modifying the ℓ/L criteria after a Code Check has been performed will invalidate the results of that Code Check. The model will be redrawn on the screen in its original colors (rather than the Code Check colors) indicating that the Code Check must be re-run.

Refer to the Assign chapter for information on how this criterion can be overridden on a member-by-member basis.
