There are four types of projects: Girder System Design Projects, Girder System Rating Projects, Line Girder Design Projects, and Line Girder Rating Projects.
Girder System Design Projects involve generating girder designs where girders are analyzed as a system. Bracing designs can be generated or defined in these projects. Girder System Design Projects in effect become Girder System Rating Projects when all dimensions have been generated or otherwise defined.
Girder System Rating Projects involve analyzing the bridge as a system of girders. All dimensions must be defined by the user in this type of project.
Line Girder Design Projects involve generating a girder design where the girder is analyzed as a continuous beam. Line Girder Design Projects in effect become Line Girder Rating Projects when all the dimensions have been generated or otherwise defined.
Line Girder Rating Projects involve analyzing a girder as a continuous beam. All dimensions must be defined by the user in this type of project.
