CHAPTER 4 "TREATMENT" 12 The filters as in the example: EXAMPLE Modify, at one level, the dimensions of the cross-sections of the beams of a plane from 25/60 to 35/70. For this modification the existence or not of the mathematical model is irrelevant. Select the command "Change Cross-section" and by activating the selection option with window select the whole floor plan. Right click and the dialog box appears. The beams selected with the window may not all be 25/60, or you may have included columns and other elements, so a filter is required to filter the selection leaving only the 25/60 beams. Select "Beam" and "B-3d", (if the mathematical model has not yet been created, then the choice of the type of linear member is irrelevant). Select the layer of the beams, that it is "Concrete Beams" and finally, activate the checkbox "From" and the command . The beams dialogue box appears on the screen, where you enter the dimensions of the beams to be modified (25/60). Activate the "In" checkbox and the command and enter the new dimensions (35/70). In case you want to modify the dimensions of all the beams independently, the procedure is the same, but without activating the "From" .
