At certain points during the design process, it may be desirable to "Freeze" the design of some or all of the beam lines. Doing so allows the user to archive completed designs or to perform "what-if" type investigations without having the reinforcement re-optimize and potentially modified.

Designs may be frozen by selecting the Process > Freeze – Single, Fence or All commands. Freezing a design on a beam line is equivalent to the Update Database command within View/Update. It marks the beam line as User Defined and saves the current reinforcement for the beam line. A frozen beam line will not be re-optimized until the design is cleared.
