Hi, I was able to fix the problem by deleting and redefining all tiles in your project. Check your settings such as slab load/thickness. I defined the floor jeans as in the model you sent. There is no network problem in the attached project.
Hello My suggestions; --Your structures should be solved as hollow block mixed structure, not cassette, (cassette spacing must be equal or close to equal so that we can accept cassettes. Enter the tiles you have given as cassette as hollow block. After making this correction, the wizard will guide you.) -- Remove the basement floor rigidity, --I think you should get the ground bearing strength given the ground safety, link:
--This building will be used right after the earthquake? (BKS=1) I=1.5 is taken, if so, do not make a hollow block, return to the column-beam-curtain system. --You can reduce the floor loads on the attic floor and remove the wall loads, --If you make a rigid solution, take the ladder loads.
