For example, create a template model of 4x4 bays, add LPAT1 case of "AUTO PATTERN LIVE" type and run the analysis. Look at the LPAT1 load case using Display > Show Loads, select LPAT 1 Case and choose the option for Analysis Model load. Program is creating 16 patterns where each panel is loaded with Live load as shown below.
