Hello there. Question 1 Before performing a performance analysis, I would normally do an earthquake-free analysis for the assignment of reinforcements in some regions, such as beam laying, where you did not anticipate what the reinforcements would be in the first place, and make an analysis in sta4cad in such a way as to remove the minimum weight of the building. In Idecad, I could not put this logic into practice. I currently have the equipment I found in the field environment, and I will enter these reinforcements into the system before the performance analysis, but for example, how will the system discard the upper reinforcement or flooring reinforcement in the beam? My second question is my building was built in 2002. As the first analysis, should I analyze by selecting the regulation before 2007 in the regulation section?
