I was asked to create a project and do static calculations. I am using the İdecad static program for the first time, I adapted the project I had for the quantity and made some progress. I could not make the raft slab part of the basement floor without beams. Can you help me how to create this tile. If there are any errors in the project, I would appreciate it if you let me know. I'm a technician. I'm a technician, so let me pass on this information as a footnote I'm sending the project as an attachment, thanking you.
