Workflow steps for steel design

  1. Prepare all project data for input into the software

  2. Create a new SSD project file

    • Define project name

    • Select design code

    • Select system

  3. Define materials

  4. Define cross sections (standard cross-sections or custom via Cross-Section Editor)

  5. System and load generation within SOFiPLUS, Teddy, Revit, Rhino or Grasshopper Interface

  6. Linear Analysis of already defined loads

  7. Define combinations

  8. Analysis of defined combination

  9. Design

    • Cross-section resistance check

    • Buckling resistance check


Working through the available tutorials the user will learn the general SOFiSTiK Steel Design Workflow.
