1- Is it normal to take one of the existing stairs in the program into account in the system and not see the reinforcement in reinforced concrete and not get the staircase drawing? Should I be equipped and hand drawn in 3D as in the old version? Or do I need to create it with the help of the Route command? 2-What could be the reason why the panels do not throw head reinforcement even though the hw/lw <2 condition is met? 3- I couldn't figure out what tf/m2 unit is. Thank you for your interest.
