Hi,
As I was designing beams with RCDC beam I have started to get same error with same step. İt says "Unhandled Exception" and gives 2 options continue and try the finalize design with that error (ıt cant finsh the design with that option) or quit the program. On other forum pages it says that problem can be solved by updating version. Even if my Staad is version 2023 I couldn't get any solution is there another reason that may cause this problem? İs this a reading error ?
