Workflow comparison

Traditional workflow
RISA-3D
  • Open RISA-3D and create new model
  • Define members, supports, loads manually
  • Run LRFD/ASD analysis
  • Extract member forces for connection design
  • Manually design each connection in spreadsheets
  • Draft fabrication drawings in AutoCAD or Tekla
Total time per project 11+ hours per project for full fabrication package
FrameAI workflow
AI-powered steel design
  • Upload structural PDF drawings
  • AI extracts BIM model and member geometry
  • AISC 360-22 member + §J connection design auto-runs
  • DSTV NC1 and AISC shop drawing PDFs download immediately
Total time per project 4 minutes to fabrication-ready output

When to use RISA-3D

RISA-3D is a capable analysis tool for engineers who already have a modeled structure and need member sizing, load combinations, and code compliance checks. If your workflow is CAD → analysis → RISA → document manually, RISA-3D works fine. FrameAI doesn’t compete in the pure analysis space — it competes in the OUTPUT space: getting from PDF drawings to fabrication-ready files without manual drafting. Use RISA-3D when you have the model built and need rigorous member checks with a tool you’ve been using for years.

Frequently asked questions

Does FrameAI require CAD modeling experience?
No. FrameAI is built for detailers and engineers who work from PDF drawings. Upload the PDF — FrameAI’s AI extracts the BIM model and produces fabrication-ready output. No CAD, no modeling from scratch.
Can FrameAI do AISC 360-22 connection design for moment frames?
Yes. FrameAI implements AISC 360-22 Section J connection design including shear connections, moment connections, base plates, and column splices. All calcs are code-verified and export as part of the DSTV NC1 delivery.
What AISC steel design codes does FrameAI support?
FrameAI supports AISC 360-22 (ASD and LRFD). Member checks cover tension, compression, bending, shear, and combined loading per the specification. Connection design follows AISC 360-22 Chapter J.
How does FrameAI’s pricing compare to RISA-3D?
FrameAI pricing is at frameai-engineering.com/pricing (free tier available). RISA-3D is $2,070/year per seat with no free tier. For a firm running 8 projects/year at a $120/hr loaded detailer rate, FrameAI saves $1,320 per project vs. a manual drafting workflow — that’s $10,560/year in labor savings.
Can I export DSTV NC1 files from FrameAI?
Yes. Every FrameAI project delivers a DSTV NC1 file ready for NC manufacturing. FrameAI also exports AISC-formatted shop drawing PDFs with member marks, cut lengths, and connection details.
