Preliminary Steel Structure Designer

Preliminary Steel Structure Designer

CATIA Preliminary Structure Designer is used to complete design of heavy structures with realistic plate and stiffener elements. It provides industry specific features to create hull structure detailed parts.

The full integration of Structure Functional Design and Structure Detailed Design allows user to retrieve Design block information that was previously defined and assessed, to perform the detailed design of the structure.

Structure engineers are able to obtain early weight, material, labor and balance estimation of the structure as well as the classification drawings including conventions. They can also extract a structural mesh of the whole ship to process global Finite Element Analysis (FEA), to get required approval of the basic design.
