Powerful Graphics

Review your 3D model so you can see the various parts of the model in 3D space. The Connection Design module will also generate a full CAD file for you to export or send off to the draftsperson for final drawings. Don't have CAD? You can produce drawings directly from within the SkyCiv Connection Design module!

  • Generate full CAD files (STEP) with bolt, plate and member connection assemblies
  • Produce clear drawings directly from the module
  • Clear and easy 2D references for user input
  • Full 3D rendering display with wireframe and viewing settings

Integrated with SkyCiv Structural 3D

All your connections forces and member properties are automatically imported into the SkyCiv Connection module - so you can view your model and connections at the same time.

  • Connections display on the graphical interface
  • Forces automatically imported from structural analysis model
  • Supports load combinations from ASCE 7-10, AS 1170, EN1 and CSA
  • Changes to your analysis model are auto-adjusted within the design module
  • Class and group steel connections together, to complete one design for multiple connections
  • Review all Connection Designs in 3D model with green/red/yellow result summaries
