I am trying to learn ideCAD program. I am using version 10 demo. I was able to add the .bak file using winrar because it does not allow .ide10demo and .bak files while making the add-on. The winrar attachment of the project was not added because it is larger than 4mb. 1- In the attached test project, I could not save the raft thickness in the semi-rigid solution with superstructure interaction. 2- It does not perform ladder analysis. I learned the drawings of this style of stairs from your youtube channel, but I couldn't get it analyzed in the program. Also, are the stair support conditions correct? 3-After the analysis, when I want to control the slab wall loads by doing Analysis Model-->Visualization-->Loads-->Load Type:Wall Loads,Combination:G, strange values like 0.035tf occur. In the same image, the values of the program on the beam look normal, like 0.625 tf/m. Is it normal?
