Hello, As a newcomer, I am asking for your help. There are many friends who explain very nice one. My question to you is, I want to write down the points that always put a question mark in my head. Please help with these downloads. If you explain step by step, I will take notes, maybe it will be useful for those who will come after me. We drew the axis in the project, we put the column according to the architectural project, we placed the beams and defined the slab so far ok, but for now 1- Do I have to calculate the slab load myself, or should I enter the slab static section and choose from there, if the program knows the load of the slab, do I just choose the cladding? I looked at it. 2- Right click on the beams and opened the static section. What do I need to enter in the moving and wall load area there. What will happen if there are no walls on some beams in the interior, how should I enter 3-- How will the load of 13.5 and 8.5 bricks on beams be? Do I always have to put gas concrete? 4-- how do I affect the roof load as a load? Do I need to enter each of the columns remaining on the slab as a load? If I am going to enter the slab, the slab load has already been calculated, should I calculate the slab load myself on the last floor 5--When placing the stairs, the last step on the staircase that goes upstairs is the slab's load. it stays on the floor, how can I make it zero on the floor, I do it on a lower floor, but I can't make zero with the floor on the top floor. 6-- When drawing stairs, should I draw more than the width of the stairwell where the stairs will come from and slide the excess towards the beams from two directions?
