Hello, in my attached project, steel lovers did not save what I did. While browsing the forum, it was stated that there was someone else, and it would be fixed with an update, but my hours were wasted until I saw this. I think that bugs in this type of program should be reported to licensed users. To avoid wasting time and fraying nerves. also the attached project was first resolved at 8,504. Added steel floor at 8.61. Although the purlins on the porch in 8.504 did not fail at 8.61, the exact same purlins entered for the first time in 8.61 will be tried again as stated in another title. In addition, while the column can define the steel braces, the roof steel braces cannot be identified. Could this be an error that the program needs to be updated or is it my mistake as a user, I wish everyone a good work.
