# Cross-Sections

> Calculate section properties for custom and thin-walled sections, and look up standard sections.

<CardGroup cols={3}>
  <Card title="Calculate Custom Cross Section Properties" icon="book" href="/docs/calculators/analysis/cross-sections/xsectionCustom">
    Analyze any arbitrary cross-section for second moments of area, section moduli, and warping and torsion constants, then link it into design calculators.
  </Card>

  <Card title="Analyze a Thin-Walled Section: Properties and Buckling" icon="calculator" href="/docs/calculators/analysis/cross-sections/xsectionCustomCFS">
    Run rapid buckling analysis of any thin-walled cross-section. A CUFSM port returns critical buckling parameters Mol, Mod, and Mo for the Direct Strength Method.
  </Card>

  <Card title="Look Up Section Properties in the Cross-Section Database" icon="calculator" href="/docs/calculators/analysis/cross-sections/xsectionDatabase">
    Look up section and material properties for Australian, US and Eurocode steel, timber and cold-formed steel sections, and link them into other calculators.
  </Card>

  <Card title="Look Up Section Properties in the Cross-Section Database (ICC)" icon="calculator" href="/docs/calculators/analysis/cross-sections/xsectionDatabaseICC">
    Look up section and material properties for US wood, steel and cold-formed steel sections, referenced to IBC 2018, 2021 or 2024.
