Using View/Update on aingle story steel columns supported by Concrete or Other material columns causes the error message "Fy must be greater than zero".
While the designs for single story steel columns supported by Concrete or Other material columns were correctly designed, an investigation of the steel columns through the View Update process resulted in an erroneous error message: Fy must be greater than zero. Reports for the steel columns correctly indicated a non-zero Fy value.
Problem solved in version 15.02.00.00. Ignore the warning on older versions.
