SkyCiv Structural 3D Integrated Section Builder

Integrated Section Builder

SkyCiv Structural 3D is fully integrated with SkyCiv Section Builder - our powerful online section analysis software:

  • Save and Load sections from our library of Australia, European, American and UK standard sections
  • Select from 15+ template shapes including I-beam, HSS, Channel etc...
  • Cold Rolled shapes such as AISI libraries
  • Your section isn't there? Simply add a custom section
  • Perform operations such as: rotate, mirror and translate.
  • Adding a section will also give the results of moment of inertia, centroids and further section properties.
  • Preset materials means you can select your material from a drop down list for fast entry!
