Concrete member data

1D member data

These settings overwrite the global settings for a specific member. Member data can easily be copy-pasted to similar members. There is differentiation based on type of member (beam, column, beam slab, rib). As in the case of setup, Member data has been also restyled. Local settings contains a contain about the same input parameters and calculation settings as the global settings in setup. Moreover, user can set his/her own value of limit deflection and limit width of crack, define more environmental classes than just one as in previous version.
