Automatic conversion
Geometry, sections, materials and supports extracted from ArchiCAD and rebuilt as a clean LIRA-SAPR analytical model nodes snapped, members aligned.
Cursor for structural engineers
Days of model rebuilding. Done in minutes.
NodeSnap turns ArchiCAD designs into verified LIRA-SAPR structural models automatically, and in sync with every revision.

The problem
The two programs don't talk. You pay for it in days.
ArchiCAD and LIRA-SAPR don't interoperate, so engineers rebuild every model by hand column by column, slab by slab. And when the architect revises the design, the redraw starts over.
2–0days
lost per building on manual model rebuilding
- Manual redraw of every column, beam, wall and slab
- Every architect revision resets the work
- Translation errors surface late in analysis, or on site
The solution
One pipeline. Zero redraws.
NodeSnap reads your architectural model, builds the analytical skeleton, and verifies every element against the source so the structural model is ready when you are.
Revision sync
The architect moved a core wall? NodeSnap diffs the new upload against the last one and updates only what changed your loads and assumptions stay put.
Element-level verification
Every converted element is checked against its source: geometry, axis alignment, section, material. Anything suspicious is flagged before you analyze.
How it works
Three steps between ArchiCAD and analysis.
- 01
Export
Save your ArchiCAD project to SAF or IFC, the formats you already have. No plugins, no special modelling rules.
SAF / IFC - 02
Convert
The AI pipeline extracts the load-bearing skeleton, resolves junctions and snaps nodes into a coherent analytical model.
AI pipeline - 03
Verify & sync
Element-by-element checks against the source model, then continuous sync as revisions arrive. Open the result straight in LIRA-SAPR.

Built for your codes
Grounded in the norms you design to.
NodeSnap is built first for engineers working across Eurocode and Georgian seismic norms where getting the analytical model right isn't optional.
