Earthquake rollover control

Hello. In the report, the distance from the center of mass to the point where the moment is taken is written for the dx and dy values in earthquake roll control. but there is nothing in common for the selected dx and dy values that I checked in two different projects. It is safer to use the shorter distance when looking at the distance from the end points of the foundation based on the center of mass on both axes. Since the moment arm will get smaller, the protective moment will also be small, but the program does not choose dx and dy accordingly. In the attached project, dx is the distance from the center of mass to the end of the nearest continuous foundation in the basement, but the distance value to the end of the continuous foundation, which is far from dy. I would appreciate it if you let me know how you choose

Hello, The program considers the smaller of the distances from the center of mass to the outer boundaries of the building in the control of the building overturning. The outer boundaries of the building are found by evaluating the outermost load-bearing elements (column, beam, shear) and the foundation boundary together. Good work
