https://www.dosyaupload.com/hXnO Hello When I level the floors and beams in my attached project, I get Aperture warning when I want to analyze. Is it okay to continue with the option Create a single aperture in floors here? [ /quote] Hello, more than one rigid diaphragm is detected due to the intermediate landing floor at -137.5 elevation. You can analyze according to a single rigid diaphragm by ticking the "creating rigid diaphragm" option from the properties of the relevant slab. Also, the elevation of the -D45 slab is not compatible with the K30 and K31 beams to which it is connected. In order for the floor not to be attached to the beams, you can create it by drawing a floor edge parallel to the beams 1-2 cm inside the beams. -Linear floor load is defined on the perimeter wall in the basement floor.Linear and point floor loads can be used to define the load on the floor, they are not taken into account on the walls (in the fully rigid solution can be used on slab floors, semi-rigid solution on all floors) -Elevator with pit We recommend modeling the wells as flat and adding the well detail to the drawings using 2D drawing possibilities.
Good work
