When I try to import a model from STAAD.PRO V8i, using "Import CIS/2" , the advance steel shown a message "Unknow representation Type! No entities imported." . I use AS 2011, SP 1 and the hotfix. When I used the AS 8.1 I can import these files without any problem, but when I update to the new version of AS, appears the problem.
Please help
Best regards!
