The program automatically creates building masses with user-specified self-weights for all the building elements that you have entered, and for the floor and roof areas inferred by the layout of the building.
Building masses are generated by for walls, floors, ceilings and flat roofs, and sloped roofs or the projected area in the horizontal plane of roofs. The program automatically divides irregularly shaped floor areas into rectangular elements for the purpose of generating loads.
Line load building masses are generated by multiplying the user-input self-weight of the element by the appropriate dimension of the surface of the element. The other dimension of the building element becomes the location and extent of the line load.
