1) Stairs are not visible in the mold plan, how can I make it look like You can make the 3D model 2D with the object split and adapt it to the mold plan with copy paste 2) In IDEstatic, when the stairs are added to the floor where they should be, is the load transferred to the floor and then to the carrier system? Otherwise, should we define the ladder loads manually as a linear load at the end of the console where the landing is located. In 7 versions, if you integrate the ladder into the carrier system in its position and elevation, and solve the system in semi-rigid analysis mode, the loads of the ladder are transferred to the system automatically. Otherwise, you must manually enter the loads of the ladder to the elements it is supported on. If it is supported on the landing, you can give it as a linear load, if it is supported on the beam, it is appropriate to give the beam as a user defined load (evenly distributed). 3) How can the stair reinforcement be continued into the console? If you can include the console in the ladder model, you will get the reinforcement you want when the account axis includes both the hrm ladder arm and the console, otherwise you have to manually extend it. 4) Shouldn't we continue the ladder calculation axis into the floor where we connect the ladder? The answer is partly given in the 3rd item, it is necessary to include the relevant flooring in the staircase model, you can reach the result by selecting the types in the staircase library, playing with the dimensions, and the staircase deformation, the alternative solution is to create your staircase completely and go to the result. I did not download your project, from what you wrote it seems that you are new to modeling, let me try to describe you the way to follow, watch the video about modeling stairs again at the end of the idestatic 6 training section in the forum, model your 4 different stairs in 3 dimensions in the light of this information, copy each model to the file by giving a different name Copy it with, you can explode the 3d models and transfer them to the mold plans. Manually enter additional loads on the ladder's support elements as described above. Now we can move on to the stair analysis, start the program, as if starting a new project, display the stairs that we copied to the file with different names in 3d, one by one, with the copy from file command, draw the stair calculation axes and the calculation axes under the staircase command to the staircase model that comes in 3d, The program will already warn you for the material definition, enter the personal and live loads in the static tab, the stair plate and landing floor thickness defult is 10 cm, (I enter at least 15 cm) after entering the desired plate thicknesses, analyze the stairs, the result with the stair drawings import the drawings and integrate them into your main project. keep this ladder solution as if it is a project so you can use it for calculation output. note: Although it is possible to perform ladder analysis within the main project, this application seems practical to me. I hope I was helpful, best regards. G.KÖSE
