Days of model
rebuilding.
Done in minutes.
NodeSnap turns ArchiCAD designs into verified LIRA-SAPR structural models. Automatically, and in sync with every revision.
One pipeline. Zero redraws.
From architectural intent to an analytical model you can work with.
Three capabilities that keep your engineering moving.
Automatic conversion
Your ArchiCAD model, rebuilt as a clean analytical skeleton. Nodes snapped. Members aligned.
Explore conversion
02 / SYNCRevision sync
Update what changed. Keep the loads and assumptions you’ve already worked through.
Explore revision sync
03 / VERIFYElement verification
Check every element against the source. Catch geometry, alignment, section, and material issues.

For the people
behind the structure.
Architectural models change. Your analytical model needs to keep up. NodeSnap connects the teams and tools on both sides of that handoff.

See the complete workflowStart with the model
you already have.
Export your ArchiCAD project as SAF or IFC. No extra plugins. No special modelling rules. Just your design, ready for the next step.
- Native SAF and IFC exchange
- Geometry, sections, and materials
- A traceable source for every element
Export
Save your architectural project in the formats you already use.
Convert
Extract the load-bearing skeleton and resolve its connections.
Verify & sync
Review the result, open it in LIRA-SAPR, and keep revisions connected.
Grounded in the norms
you design to.
Built first for engineers working across Eurocode and Georgian
seismic norms, where the analytical model matters.

Know what changed. Know what needs a look.
NodeSnap checks converted elements against the architectural source and flags discrepancies before analysis. Engineering decisions stay with you.
Which tools does NodeSnap connect?
NodeSnap’s core workflow connects ArchiCAD architectural designs to LIRA-SAPR analytical models. It reads SAF and IFC exports, then converts and checks the structural elements against their source.
Do I need to change how I model?
Start with a SAF or IFC export from ArchiCAD. The workflow is designed around the formats you already use, without extra plugins or special modelling conventions. A demo is a good place to discuss your project’s particular requirements.
What happens when the architect makes a change?
NodeSnap compares the revised upload with the previous model, identifies what changed, and updates those elements while preserving your loads and assumptions.
What does element verification check?
Geometry, axis alignment, member sections, and materials are compared against the source model. Suspicious results are flagged for your review before you run an analysis.
Does NodeSnap replace structural analysis?
No. NodeSnap prepares and checks the analytical model so you can continue your analysis in LIRA-SAPR. The engineer remains responsible for reviewing the model, engineering assumptions, and final design.
How can I see it with my workflow?
Book a demo and tell us about your modelling workflow. Your request goes directly to the NodeSnap team so you can discuss your tools, project, and next steps.
